具体实施方式Detailed ways
下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是,此处所描述的具体实施例仅仅用于解释本发明,而非对本发明的限定。另外还需要说明的是,为了便于描述,附图中仅示出了与本发明相关的部分而非全部内容。The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should also be noted that, for ease of description, only some, but not all, of the present invention are shown in the drawings.
实施例一Embodiment 1
图1为本发明实施例一提供的一种自动调节背光的方法的流程图。本实施例提供的自动调节背光的方法适用于根据交互智能平板的翻转情况自动调整背光亮度的情景。本实施例提供的自动调节背光的方法可以由自动调节背光的装置执行,该装置可以通过软件和/或硬件的方式实现,并集成在交互智能平板中。FIG. 1 is a flowchart of a method for automatically adjusting a backlight according to Embodiment 1 of the present invention. The method for automatically adjusting the backlight provided by the embodiment is suitable for automatically adjusting the brightness of the backlight according to the flipping condition of the interactive smart tablet. The method for automatically adjusting the backlight provided by the embodiment may be performed by a device that automatically adjusts the backlight, and the device may be implemented by software and/or hardware and integrated in the interactive smart tablet.
具体的,交互智能平板是通过触控技术对显示在显示平板上的内容进行操 控和实现人机交互操作的一体化设备,其集成了电子白板、幕布、音响、电视机、视频会议终端等多种功能。其中,显示平板的显示屏包括液晶显示屏等。在本实施例中,设定交互智能平板放置在对应的支撑架上且可以围绕一水平线翻转,其具体的翻转方式和可翻转的范围可以根据实际情况进行设定。图2为本实施例提供的交互智能平板翻转过程第一侧视图。其中,交互智能平板以底边为水平线进行翻转。图3为本实施例提供的交互智能平板翻转过程第二侧视图。其中,交互智能平板以交互智能平板的中间轴线为水平线进行翻转。优选的,交互智能平板的翻转范围为由水平放置状态翻转至竖直放置状态,其中,水平放置状态为交互智能平板显示面朝上且水平放置的状态,竖直放置为显示屏与水平面垂直的状态。此时,交互智能平板在翻转范围内的最大翻转角度为90度。图2和图3仅为示例性描述,并不限定具体的翻转过程。Specifically, the interactive smart tablet operates the content displayed on the display tablet through touch technology. An integrated device that controls and implements human-computer interaction operations, which integrates various functions such as an electronic whiteboard, a screen, an audio, a television, and a video conferencing terminal. The display screen of the display panel includes a liquid crystal display or the like. In this embodiment, the interactive smart tablet is placed on the corresponding support frame and can be flipped around a horizontal line. The specific flip mode and the reversible range can be set according to actual conditions. FIG. 2 is a first side view of the interactive smart tablet flipping process provided by the embodiment. Among them, the interactive smart tablet is flipped with the bottom edge as a horizontal line. FIG. 3 is a second side view of the interactive smart tablet flipping process provided by the embodiment. The interactive smart tablet is flipped with a horizontal line of the interactive smart tablet as a horizontal line. Preferably, the flipping range of the interactive smart tablet is from a horizontal placement state to a vertical placement state, wherein the horizontal placement state is a state in which the interactive smart flat panel display face is up and horizontally placed, and the vertical placement is perpendicular to the display screen and the horizontal plane. status. At this time, the maximum flip angle of the interactive smart tablet in the flip range is 90 degrees. 2 and 3 are merely exemplary descriptions and do not define a specific flipping process.
参考图1,本实施例提供的方法具体包括:Referring to FIG. 1, the method provided in this embodiment specifically includes:
S110、获取交互智能平板翻转后所在平面与水平面之间的当前角度值。S110. Obtain a current angle value between a plane and a horizontal plane after the interactive smart tablet is flipped.
具体的,交互智能平板翻转后所在平面也可以称为交互智能平板当前所在平面,其指在当前采样时刻交互智能平板所在的平面。进一步的,在获取当前角度值时,可以设定获取间隔,间隔获取当前角度值,还可以是当检测到交互智能平板被翻转时,间隔获取当前角度值,也可以是当检测到交互智能平板被翻转后,当确认翻转结束时,获取当前角度值。其中,确认翻转结束可以是在一定时间范围(如2分钟)内未检测到交互智能平板被翻转。Specifically, the plane where the interactive smart tablet is flipped may also be referred to as the current plane of the interactive smart tablet, which refers to the plane where the smart tablet is located at the current sampling time. Further, when the current angle value is obtained, the acquisition interval may be set, and the current angle value may be obtained by the interval. When the interaction smart tablet is detected to be flipped, the interval may obtain the current angle value, or may be when the interaction smart tablet is detected. After being flipped, when the end of the flip is confirmed, the current angle value is obtained. Wherein, it is confirmed that the end of the flipping is that the interactive smart tablet is not detected to be flipped within a certain time range (for example, 2 minutes).
可选的,当前角度值为交互智能平板翻转后所在平面与水平面之间的最小夹角值。一般而言,当交互智能平板翻转后所在平面与水平面相交时,包括四个夹角值,且每相邻的两个夹角值的和为180°其中,最小夹角值的范围在0°至90°之间,0°为交互智能平板翻转后所在平面与水平面重合,90°为交互智 能平板翻转后所在平面与水平面垂直。例如,图4为交互智能平板翻转后所在平面与水平面的第一相对位置示意图,图5为交互智能平板翻转后所在平面与水平面的第二相对位置示意图。其中,图5和图4中显示屏的朝向如箭头所示,此时,图4和图5中显示屏朝向相反,但是由于翻转后所在平面12与水平面13的最小夹角值相同,因此,确定交互智能平板在图4或者图5所示的翻转后所在平面12时,对应的当前角度值相同,均为45°。还可选的,当前角度值为交互智能平板翻转后所在平面与水平面之间的最大夹角值,此时,当前角度值的最小值为90°,最大值为180°。也可选的,设定交互智能平板的显示屏朝向的角度为当前角度值。此时,当前角度值的最小值为0°,最大值为180°。例如,对于图4所示的位置关系,交互智能平板的当前角度值为45°,对于图5所示的位置关系,交互智能平板的当前角度值为135°。需要说明的是,为了便于理解,图4和图5中涉及的平面均以平面中的直线替代。Optionally, the current angle value is a minimum angle between the plane and the horizontal plane after the interactive smart tablet is flipped. Generally, when the plane of the interactive smart tablet is inverted and intersects with the horizontal plane, the angle includes four angles, and the sum of the two adjacent angle values is 180°, and the minimum angle value ranges from 0°. Between 90° and 0°, the plane where the interactive smart tablet is flipped overlaps with the horizontal plane, and 90° is the interactive wisdom. The plane where the flat panel can be flipped is perpendicular to the horizontal plane. For example, FIG. 4 is a schematic diagram of a first relative position of a plane and a horizontal plane after the interactive smart tablet is flipped, and FIG. 5 is a second relative position of the plane and the horizontal plane after the interactive smart tablet is flipped. The orientation of the display screen in FIGS. 5 and 4 is as indicated by the arrow. At this time, the display screens in FIG. 4 and FIG. 5 are opposite in direction, but since the plane of the plane 12 after the flip is the same as the minimum angle of the horizontal plane 13, the When the interactive smart panel is in the plane 12 after the flipping shown in FIG. 4 or FIG. 5, the corresponding current angle values are the same, both being 45 degrees. Optionally, the current angle value is a maximum angle between the plane and the horizontal plane after the interactive smart tablet is flipped. At this time, the minimum value of the current angle value is 90°, and the maximum value is 180°. Optionally, the angle of the display orientation of the interactive smart tablet is set to a current angle value. At this time, the minimum value of the current angle value is 0°, and the maximum value is 180°. For example, for the positional relationship shown in FIG. 4, the current angle value of the interactive smart tablet is 45°, and for the positional relationship shown in FIG. 5, the current angle value of the interactive smart tablet is 135°. It should be noted that, for ease of understanding, the planes involved in FIGS. 4 and 5 are all replaced by straight lines in a plane.
具体的,可以通过角度测量的相关装置采集的数据确定当前角度值,其中,相关装置可以是重力传感器和/或倾角传感器。需要说明的是,相关装置也可以是测量翻转角度的装置,如陀螺仪,其只能测量翻转过程中对应的翻转幅度,进一步的,可以设定交互智能平板翻转前的初始角度值固定,进而可以根据陀螺仪确定当前角度值。然而,一般情况下,交互智能平板翻转前的初始角度值并不固定,此时,可以结合陀螺仪和重力传感器或陀螺仪和倾角传感器确定当前角度值。Specifically, the current angle value may be determined by data collected by the related device of the angle measurement, wherein the related device may be a gravity sensor and/or a tilt sensor. It should be noted that the related device may also be a device for measuring the flip angle, such as a gyroscope, which can only measure the corresponding flip amplitude during the flipping process. Further, the initial angle value before the flipping of the interactive smart tablet can be set, and then The current angle value can be determined based on the gyroscope. However, in general, the initial angle value before the interactive smart tablet is flipped is not fixed. At this time, the current angle value can be determined by combining the gyroscope and the gravity sensor or the gyroscope and the tilt sensor.
S120、根据当前角度值确定对应的目标背光亮度。S120. Determine a corresponding target backlight brightness according to the current angle value.
一般而言,目标背光亮度为一个具体的光亮度值,其可以使用户观看显示屏时显示亮度适宜。用户使用交互智能平板过程中,如果用户将交互智能平板水平放置,当显示面朝上时一般是用户对显示屏执行触控操作的场景,此时, 默认用户距离交互智能平板的距离较近,当显示面朝下时一般是用户不需要观看显示屏的场景。如果用户将交互智能平板竖直放置,一般是使至少一个用户观看显示屏的场景,即使某一个用户对显示屏执行了触控操作但仍是以让至少一个用户观看显示内容为目的,此时,默认用户距离交互智能平板较远。据此,本实施例中设定当交互智能平板竖直放置时,目标背光亮度较大,其等于或小于交互智能设备可以达到的最大背光亮度。当交互智能平板水平放置时,目标背光亮度较小,其等于或大于交互智能设备可以达到的最小背光亮度。当交互智能平板位于水平放置和竖直放置之间时,目标背光亮度在水平放置和竖直放置对应的目标背光亮度之间。可选的,显示屏朝上水平放置和显示屏朝下水平放置对应的目标背光亮度可以相同也可以不同。其中,设置水平放置或竖直放置时对应的背光亮度并不是最小背光亮度或最大背光亮度的好处是可以使用户根据自身需求继续降低或调高背光亮度。In general, the target backlight brightness is a specific light brightness value, which can make the display brightness suitable when the user views the display screen. In the process of using the interactive smart tablet, if the user places the interactive smart tablet horizontally, when the display face is up, the user generally performs a touch operation on the display screen. The default user is closer to the interactive smart tablet, and when the display face is facing down, the user does not need to view the display. If the user places the interactive smart tablet vertically, generally at least one user views the scene of the display screen, even if a user performs a touch operation on the display screen, the purpose is to let at least one user view the display content. The default user is farther away from the interactive smart tablet. Accordingly, in this embodiment, when the interactive smart tablet is placed vertically, the target backlight has a large brightness, which is equal to or smaller than the maximum backlight brightness that the interactive smart device can achieve. When the interactive smart tablet is placed horizontally, the target backlight is less bright, which is equal to or greater than the minimum backlight brightness that the interactive smart device can achieve. When the interactive smart tablet is placed between horizontal and vertical placement, the target backlight brightness is placed between the horizontally placed and vertically corresponding target backlight brightness. Optionally, the display may be placed horizontally upward and the display may be horizontally placed corresponding to the target backlight brightness may be the same or different. Among them, the advantage of setting the corresponding backlight brightness when the horizontal or vertical placement is not the minimum backlight brightness or the maximum backlight brightness is that the user can continue to reduce or increase the backlight brightness according to his own needs.
可选的,预先设定不同当前角度值对应的目标背光亮度,进而根据当前角度值查找对应的目标背光亮度。其中,设定方式可以根据实情使用情况设定。还可选的,当前角度值为交互智能平板翻转后所在平面与水平面之间的最小夹角值时,也可以计算当前角度值与翻转前的初始角度值之间的差值,进而根据差值确定对应的背光调节幅度,并根据初始角度值对应的初始背光亮度以及背光调整幅度确定目标背光亮度。其中初始角度值为交互智能平板翻转前所在平面与水平面之间的最小夹角值。一般而言,差值可以为正数、0和负数,且差值的绝对值越大,背光调整幅度越大。如果差值为正数,则说明交互智能平板相对于翻转前更接近竖直放置状态,因此,对应的背光调整幅度应为背光增强调整幅度,差值为负数则反之。Optionally, the target backlight brightness corresponding to different current angle values is preset, and then the corresponding target backlight brightness is searched according to the current angle value. Among them, the setting method can be set according to the actual use situation. Optionally, when the current angle value is the minimum angle between the plane and the horizontal plane after the interactive smart tablet is flipped, the difference between the current angle value and the initial angle value before the flipping may also be calculated, and then the difference is further determined according to the difference. The corresponding backlight adjustment amplitude is determined, and the target backlight brightness is determined according to the initial backlight brightness corresponding to the initial angle value and the backlight adjustment amplitude. The initial angle value is the minimum angle between the plane and the horizontal plane before the interactive smart tablet is flipped. In general, the difference can be positive, 0, and negative, and the larger the absolute value of the difference, the larger the backlight adjustment. If the difference is a positive number, the interactive smart tablet is placed closer to the vertical state than before the flipping. Therefore, the corresponding backlight adjustment amplitude should be the backlight enhancement adjustment range, and the difference is negative.
S130、调整交互智能平板的背光亮度至目标背光亮度。 S130. Adjust the backlight brightness of the interactive smart tablet to the target backlight brightness.
具体的,将交互智能平板的背光亮度调整至目标背光亮度,其具体的调整方式可以根据实际情况进行设定,调整背光亮度后,使用户在当前角度值下观看显示屏时,显示亮度适宜。Specifically, the backlight brightness of the interactive smart tablet is adjusted to the target backlight brightness, and the specific adjustment manner can be set according to actual conditions. After adjusting the backlight brightness, the user can display the brightness when viewing the display screen under the current angle value.
可选的,用户与交互智能平板的距离不同时双眼观看显示屏的最佳显示亮度不同,交互智能平板所在环境的光照亮度不同时双眼观看显示屏的最佳显示亮度也不同。因此,可以根据用户与交互智能平板的距离和/或交互智能平板所在环境的光照亮度修正目标背光亮度。例如,在确定目标背光亮度前,确定用户与交互智能平板的距离和/或交互智能平板所在环境的光照亮度对应的最佳背光亮度范围,并将该范围内的最低值作为水平放置时的目标背光亮度,最高值作为竖直放置时的目标背光亮度,进而根据当前角度值确定目标背光亮度,而后调整显示亮度至目标背光亮度。又如,根据当前角度值确定目标背光亮度后,根据用户与交互智能平板的距离和/或交互智能平板所在环境的光照亮度修正目标背光亮度,而后调整背光亮度至修正后的目标背光亮度。Optionally, when the distance between the user and the interactive smart tablet is different, the optimal display brightness of the binocular viewing display screen is different, and the optimal display brightness of the binocular viewing display screen is different when the illumination brightness of the environment where the interactive smart tablet is located is different. Therefore, the target backlight brightness can be corrected according to the distance between the user and the interactive smart tablet and/or the brightness of the environment in which the smart tablet is located. For example, before determining the target backlight brightness, determining the distance between the user and the interactive smart tablet and/or the optimal backlight brightness range corresponding to the illumination brightness of the environment in which the smart tablet is located, and using the lowest value in the range as the target when horizontally placed The brightness of the backlight is the highest value as the target backlight brightness when placed vertically, and then the target backlight brightness is determined according to the current angle value, and then the display brightness is adjusted to the target backlight brightness. For another example, after determining the target backlight brightness according to the current angle value, the target backlight brightness is corrected according to the distance between the user and the interactive smart tablet and/or the illumination brightness of the environment in which the smart tablet is located, and then the backlight brightness is adjusted to the corrected target backlight brightness.
本实施例提供的技术方案,通过交互智能平板翻转后所在平面与水平面之间的当前角度值确定对应的目标背光亮度,并调整交互智能平板的背光亮度至目标背光亮度的技术方案,实现了在交互智能平板可翻转时,根据翻转后的当前角度值自动调整交互智能平板的背光亮度,以保证背光亮度为用户的适宜亮度,同时,无需用户手动调整,提升了用户的使用体验。The technical solution provided by the embodiment provides a technical solution for determining the corresponding target backlight brightness by adjusting the current target value between the plane and the horizontal plane after the smart tablet is flipped, and adjusting the backlight brightness of the interactive smart tablet to the target backlight brightness. When the interactive smart tablet can be flipped, the backlight brightness of the interactive smart tablet is automatically adjusted according to the current angle value after the flipping, so as to ensure the brightness of the backlight is suitable for the user, and the user does not need manual adjustment, thereby improving the user experience.
实施例二Embodiment 2
图6为本发明实施例二提供的一种自动调节背光的方法的流程图。本实施例是在上述实施例的基础上进行具体化。具体的,参考图6,本实施例提供的自动调节背光的方法具体包括: FIG. 6 is a flowchart of a method for automatically adjusting a backlight according to Embodiment 2 of the present invention. This embodiment is embodied on the basis of the above embodiment. Specifically, referring to FIG. 6, the method for automatically adjusting the backlight provided by this embodiment specifically includes:
S210、通过重力传感器和/或倾角传感器采集的数据确定交互智能平板翻转后所在平面与水平面之间的当前角度值。S210. The data collected by the gravity sensor and/or the tilt sensor determines a current angle value between the plane and the horizontal plane after the interactive smart tablet is flipped.
具体的,重力传感器可以将感知的重力转换成对应的电信号,其中,重力传感器采集的重力值并不是指交互智能平板的实际重力值,而是在翻转过程由重力引起的加速度值。通过重力传感器确定当前角度值具体为:通过重力传感器测量交互智能平板位于翻转后所在平面时由于重力引起的加速度,根据加速度计算出交互智能平板翻转后所在平面相对于水平面的倾斜角度,根据该倾斜角度确定交互智能平板的当前角度值。由于通过重力传感器测得的当前角度值为某个时刻的角度值,其不涉及具体的翻转过程。因此,无论交互智能平板是否在上电时翻转,只要翻转后交互智能平板某一时刻处于上电状态,就可通过重力传感器确定角度值。Specifically, the gravity sensor can convert the sensed gravity into a corresponding electrical signal, wherein the gravity value collected by the gravity sensor does not refer to the actual gravity value of the interactive smart tablet, but the acceleration value caused by gravity during the flipping process. The current angle value determined by the gravity sensor is specifically: the gravity sensor is used to measure the acceleration caused by gravity when the interactive smart tablet is located on the plane after the flipping, and the tilt angle of the plane relative to the horizontal plane after the interactive smart tablet is flipped is calculated according to the acceleration, according to the tilt The angle determines the current angle value of the interactive smart tablet. Since the current angle value measured by the gravity sensor is an angle value at a certain moment, it does not involve a specific flipping process. Therefore, regardless of whether the interactive smart tablet is flipped during power-on, the angle value can be determined by the gravity sensor as long as the interactive smart tablet is powered on at a certain time after the flipping.
进一步的,倾角传感器可以测量被测平面与水平面间的夹角,本实施例中被测平面为交互智能平板翻转后所在平面。由于倾角传感器是静态测量,无需感知具体的翻转过程,因此,无论交互智能平板是否在上电时翻转,只要翻转后交互智能平板某一时刻处于上电状态,就可通过倾角传感器确定当前角度值。Further, the tilting sensor can measure the angle between the measured plane and the horizontal plane. In this embodiment, the measured plane is the plane where the interactive smart tablet is flipped. Since the tilt sensor is a static measurement, there is no need to perceive a specific flipping process.

After determining the current angle value, it is only necessary to find the optimal backlight brightness corresponding to the current angle value as the target backlight brightness according to the angle and brightness correspondence. The method for determining the optimal backlight brightness at each current angle value is not limited, as determined by the designer of the interactive smart tablet and/or set and adjusted by the interactive smart tablet according to the user's usage habits.
还可选的,当前角度值为交互智能平板翻转后所在平面与水平面之间的最 小夹角值,对应关系的确定方式为:Y=L1-(L1-L2)sin(90-X1),或,Y=(L1-L2)*X1/90+L2,其中,当前角度值为X1度,Y为目标背光亮度,交互智能平板竖直放置时对应的目标背光亮度为L1,交互智能平板水平放置时对应的目标背光亮度为L2,L1>L2;当前角度值为交互智能平板翻转后所在平面与水平面之间的最大夹角值,对应关系的确定方式为:Y=L2+(L1-L2)sinX1,或,Y=L1-(L1-L2)*(X1-90)/90;当前角度值为显示屏朝向的角度,对应的计算规则为:Y=L1-|X1-90|*(L1-L2)/90。Optionally, the current angle value is the highest between the plane and the horizontal plane after the interactive smart tablet is flipped.

为了保证最终调整的背光亮度更加符合用户实际需求,在确定目标背光亮度后,根据用户与交互智能平板之间的距离值和/或交互智能平板所在环境的光照亮度修正目标背光亮度。其具体包括下述至少一种方案:In order to ensure that the final adjusted backlight brightness is more in line with the actual needs of the user, after determining the target backlight brightness, the target backlight brightness is corrected according to the distance between the user and the interactive smart tablet and/or the illumination brightness of the environment in which the smart tablet is located. It specifically includes at least one of the following solutions:
方案一、获取用户与交互智能平板之间的距离值,根据距离值修正目标背光亮度。Solution 1: Obtain the distance value between the user and the interactive smart tablet, and correct the target backlight brightness according to the distance value.
其中,用户与交互智能平板之间的距离为用户与显示屏的距离。一般而言,当用户与显示屏距离较小时,背光亮度应适当降低以避免显示屏的光亮刺眼。当用户与显示屏距离较大时,背光亮度应适当提高以使用户清楚观看。据此,可以预先设定不同距离值下的第一背光亮度修正幅度,以修正目标背光亮度。The distance between the user and the interactive smart tablet is the distance between the user and the display screen. In general, when the distance between the user and the display screen is small, the brightness of the backlight should be appropriately lowered to avoid the glare of the display screen. When the distance between the user and the display screen is large, the brightness of the backlight should be appropriately increased to make the user clearly watch. Accordingly, the first backlight brightness correction amplitude at different distance values can be set in advance to correct the target backlight brightness.
具体的,通过接近传感器、红外距离传感器和/或摄像头等装置采集的数据确定用户与交互智能平板的距离。当测量到多个用户的距离时,可以将计算得到的距离平均值作为最终的距离值,或者根据用户数量和每个用户的距离设定每个距离的加权值,并将计算得到的加权平均值作为最终的距离值。Specifically, the data collected by the proximity sensor, the infrared distance sensor, and/or the camera determines the distance between the user and the interactive smart tablet. When the distances of multiple users are measured, the calculated distance average value may be used as the final distance value, or the weighting value of each distance may be set according to the number of users and the distance of each user, and the calculated weighted average will be calculated. The value is taken as the final distance value.
方案二、采集交互智能平板所在环境的光照亮度,根据光照亮度修正目标背光亮度。 Solution 2: Collect the illumination brightness of the environment where the interactive smart tablet is located, and correct the target backlight brightness according to the illumination brightness.
一般而言,当交互智能平板所在环境的光照亮度较低时,背光亮度应适当降低以避免显示屏的光亮刺眼。当交互智能平板所在环境的光照亮度较高时,背光亮度应适当提高以使用户清楚观看。据此,可以预先设定不同光照亮度下的第二背光亮度修正幅度,以修正目标背光亮度。In general, when the brightness of the environment in which the interactive smart tablet is located is low, the brightness of the backlight should be appropriately lowered to avoid the glare of the display. When the illumination brightness of the environment where the interactive smart tablet is located is high, the backlight brightness should be appropriately increased to make the user clearly watch. Accordingly, the second backlight brightness correction amplitude under different illumination brightnesses can be preset to correct the target backlight brightness.
其中,可以通过交互智能平板中配置的亮度传感器或者与交互智能平板关联的其他设备配置的亮度传感器采集的数据确定所在环境的光照亮度。The brightness of the environment may be determined by using a brightness sensor configured in the interactive smart tablet or a brightness sensor configured by another device associated with the interactive smart tablet.
S240、调整交互智能平板的背光亮度至目标背光亮度。S240. Adjust the backlight brightness of the interactive smart tablet to the target backlight brightness.
此时,将交互智能平板的背光亮度调整至修正后的目标背光亮度。At this time, the backlight brightness of the interactive smart tablet is adjusted to the corrected target backlight brightness.
下面对本实施例提供的方法进行示例性描述:The method provided by this embodiment is exemplarily described below:

The current angle value corresponding to the horizontal placement state is 0°, and the current angle value corresponding to the vertical placement state is 90°. Further, when the current angle value is 0°, the corresponding target backlight brightness is L2, and when the current angle value is 90°, the corresponding target backlight brightness is L1, and the current angle value is any value between 0° and 90°, corresponding to The target backlight brightness is between L1 and L2, and the larger the current angle value, the greater the corresponding target backlight brightness. Further, the corresponding target backlight brightness is determined according to the current angle value, and the backlight brightness of the interactive smart tablet is adjusted to the target backlight brightness.
本实施例提供的技术方案,通过确定当前交互智能平板的当前角度值,并查找到与当前角度值对应的目标背光亮度后,修正目标背光亮度并将交互智能平板的背光亮度调节至目标背光亮度的技术手段,实现了通过用户使用交互智能平板时的当前角度值自动调节背光亮度,同时结合用户与交互智能平板的距离、交互智能平板所在环境的光照亮度等参数修正背光亮度,使得最终得到的背光亮度更加符合用户的实际需求,提升了用户的使用体验。 In the technical solution provided by the embodiment, after determining the current angle value of the current interactive smart tablet and finding the target backlight brightness corresponding to the current angle value, the target backlight brightness is corrected and the backlight brightness of the interactive smart tablet is adjusted to the target backlight brightness.

实施例三Embodiment 3
图7为本发明实施例三提供的一种自动调节背光的方法的流程图。本实施例提供的方法是在上述实施例的基础上进行具体化。在本实施例中,设定当前角度值为交互智能平板翻转后所在平面与水平面之间的最小夹角值。具体的,参考图7,本实施例提供的自动调节背光的方法具体包括:FIG. 7 is a flowchart of a method for automatically adjusting a backlight according to Embodiment 3 of the present invention. The method provided in this embodiment is embodied on the basis of the above embodiments. In this embodiment, the current angle value is set to be the minimum angle between the plane and the horizontal plane after the interactive smart tablet is flipped. Specifically, referring to FIG. 7 , the method for automatically adjusting the backlight provided by the embodiment includes:
S310、通过重力传感器和/或倾角传感器采集的数据确定交互智能平板翻转后所在平面与水平面之间的当前角度值。S310. The data collected by the gravity sensor and/or the tilt sensor determines a current angle value between a plane where the interactive smart tablet is flipped and a horizontal plane.
S320、计算当前角度值与初始角度值的差值。S320. Calculate a difference between the current angle value and the initial angle value.
具体的,初始角度值为交互智能平板翻转前所在平面与水平面之间的最小夹角值。其中,交互智能平板翻转前所在平面为相对于当前采样时刻的前一采样时刻时交互智能平板所在的平面。可选的,获取初始角度值时,同步获取对应的背光亮度并记为初始背光亮度。Specifically, the initial angle value is a minimum angle between the plane and the horizontal plane before the interactive smart tablet is flipped. The plane where the interactive smart tablet is flipped before is the plane where the interactive smart tablet is located relative to the previous sampling moment of the current sampling moment. Optionally, when the initial angle value is obtained, the corresponding backlight brightness is synchronously acquired and recorded as the initial backlight brightness.
进一步的,由于交互智能平板的翻转方向不固定,因此,当前角度值可能大于、等于或者小于初始角度值,因此确定差值时,差值可能是正数、0或负数。Further, since the flipping direction of the interactive smart tablet is not fixed, the current angle value may be greater than, equal to, or less than the initial angle value, so when the difference is determined, the difference may be a positive number, a zero or a negative number.
例如,图8为交互智能平板翻转后所在平面与水平面的第三相对位置示意图,其中,翻转后所在平面32与水平面31的当前角度值为45°。图9为交互智能平板翻转前所在平面与水平面的第一相对位置示意图,其中,翻转前所在平面33与水平面31的初始角度值为30°,此时,对应的差值为15°。图10为交互智能平板翻转前所在平面与水平面的第二相对位置示意图,其中,翻转前所在平面33与水平面31的初始角度值为60°,此时,对应的差值为-15°。需要说明的是,为了便于理解,图8、图9以及图10中涉及的平面均以直线替代,且交互智能平板显示屏的朝向如箭头所示。 For example, FIG. 8 is a schematic diagram of a third relative position of the plane and the horizontal plane after the interactive smart tablet is flipped, wherein the current angle of the plane 32 and the horizontal plane 31 after the flipping is 45°. 9 is a schematic diagram of a first relative position of a plane and a horizontal plane before the flipping of the interactive smart tablet, wherein the initial angle of the plane 33 and the horizontal plane 31 before the flipping is 30°, and the corresponding difference is 15°. 10 is a schematic diagram of a second relative position of the plane and the horizontal plane before the flipping of the interactive smart tablet, wherein the initial angle of the plane 33 and the horizontal plane 31 before the flipping is 60°, and the corresponding difference is -15°. It should be noted that, for ease of understanding, the planes involved in FIGS. 8, 9, and 10 are all replaced by straight lines, and the orientation of the interactive smart flat panel display is as indicated by the arrow.
S330、确定差值对应的背光调节幅度。S330. Determine a backlight adjustment range corresponding to the difference.
一般而言,差值的绝对值越大说明翻转幅度越大,对应的背光调节幅度也应越大。即差值的绝对值与背光调节幅度成正比。In general, the larger the absolute value of the difference, the larger the flipping amplitude, and the corresponding backlight adjustment amplitude should be larger. The absolute value of the difference is proportional to the amplitude of the backlight adjustment.
进一步的,预先设定不同差值对应的背光调节幅度,其可以由交互智能平板的设计人员通过测试确定和/或由交互智能平板根据用户的使用习惯自行设定和调整。也可以根据公式:W=X2*(L3-L4)/90确定。其中,X2为差值,W为背光调节幅度,L3为当前角度值为90°时对应的最大背光亮度值,L4为当前角度值为0°时对应的最小背光亮度值。Further, the backlight adjustment range corresponding to the different difference values is preset, which may be determined by the designer of the interactive smart tablet through testing and/or set and adjusted by the interactive smart tablet according to the user's usage habits. It can also be determined according to the formula: W=X2*(L3-L4)/90. Wherein, X2 is the difference, W is the backlight adjustment amplitude, L3 is the corresponding maximum backlight brightness value when the current angle value is 90°, and L4 is the corresponding minimum backlight brightness value when the current angle value is 0°.
进一步的,确定差值对应的背光调节幅度包括:差值为正值时,确定与差值对应的背光增强调节幅度;差值为负值时,确定与差值对应的背光降低调节幅度。Further, determining the backlight adjustment amplitude corresponding to the difference comprises: determining a backlight enhancement adjustment amplitude corresponding to the difference when the difference is a positive value; and determining a backlight reduction adjustment amplitude corresponding to the difference when the difference is a negative value.
具体的,背光增强调节幅度为背光亮度增大的幅度,背光降低调节幅度为背光亮度减小的幅度。由于交互智能平板的翻转方向不固定,因此,交互智能平板翻转时可能是增大了其所在平面与水平面间的最小角度值,也可以是减小了其所在平面与水平面间的最小角度值。差值为正,说明翻转后交互智能平板的当前角度值大于初始角度值,即交互智能平板翻转后更接近于竖直放置状态,因此,当前角度值对应的背光亮度应当大于初始角度值对应的背光亮度,即翻转后背光亮度应该增强,此时,确定的背光调节幅度为背光增强调节幅度。差值为负,说明翻转后交互智能平板的当前角度值小于初始角度值,即交互智能平板翻转后更接近于水平放置状态,因此,当前角度值对应的背光亮度应当小于初始角度值对应的背光亮度,即翻转后背光亮度应该降低,此时,确定的背光调节幅度为背光降低调节幅度。Specifically, the backlight enhancement adjustment amplitude is an amplitude of the backlight brightness increase, and the backlight reduction adjustment amplitude is a magnitude of the backlight brightness reduction. Since the flipping direction of the interactive smart tablet is not fixed, the interactive smart tablet may increase the minimum angle between the plane and the horizontal plane, or reduce the minimum angle between the plane and the horizontal plane. The difference is positive, indicating that the current angle value of the interactive smart tablet after flipping is greater than the initial angle value, that is, the interactive smart tablet is closer to the vertical placement state after being flipped. Therefore, the backlight brightness corresponding to the current angle value should be greater than the initial angle value. The brightness of the backlight, that is, the brightness of the backlight after the flip should be increased. At this time, the determined backlight adjustment amplitude is the backlight enhancement adjustment range. The difference is negative, indicating that the current angle value of the interactive smart tablet after flipping is smaller than the initial angle value, that is, the interactive smart tablet is closer to the horizontal placement state after being flipped. Therefore, the backlight brightness corresponding to the current angle value should be smaller than the backlight corresponding to the initial angle value. The brightness, that is, the backlight brightness after the flip should be lowered. At this time, the determined backlight adjustment range is the backlight reduction adjustment range.
S340、根据背光调节幅度以及与初始角度值对应的初始背光亮度确定目标 背光亮度。S340. Determine a target according to a backlight adjustment amplitude and an initial backlight brightness corresponding to the initial angle value. Backlight brightness.
其中,初始背光亮度为交互智能平板在初始角度值时对应的背光亮度。具体的,当背光调节幅度为背光增强调节幅度时,目标背光亮度为初始背光亮度与背光增强调节幅度中具体值的和,当背光调节幅度为背光降低调节幅度时,目标背光亮度为初始背光亮度减去背光降低调节幅度中具体值的差。如果背光增强调节幅度为正值,背光降低调节幅度为负值,那么目标背光亮度便可以为初始背光亮度与背光增强调节幅度的和,或者,初始背光亮度与背光降低调节幅度的和。The initial backlight brightness is the corresponding backlight brightness of the interactive smart tablet at the initial angle value. Specifically, when the backlight adjustment amplitude is the backlight enhancement adjustment range, the target backlight brightness is the sum of the specific values of the initial backlight brightness and the backlight enhancement adjustment range. When the backlight adjustment amplitude is the backlight reduction adjustment range, the target backlight brightness is the initial backlight brightness. Subtracting the backlight reduces the difference in the specific value of the adjustment amplitude. If the backlight enhancement adjustment amplitude is positive and the backlight reduction adjustment amplitude is negative, the target backlight luminance may be the sum of the initial backlight luminance and the backlight enhancement adjustment amplitude, or the sum of the initial backlight luminance and the backlight reduction adjustment amplitude.
S350、根据修正参数修正目标背光亮度。S350. Correct the target backlight brightness according to the correction parameter.
其具体包括下述至少一种方案:It specifically includes at least one of the following solutions:
方案一、获取用户与交互智能平板之间的距离值,根据距离值修正目标背光亮度。Solution 1: Obtain the distance value between the user and the interactive smart tablet, and correct the target backlight brightness according to the distance value.
方案二、采集交互智能平板所在环境的光照亮度,根据光照亮度修正目标背光亮度。Solution 2: Collect the illumination brightness of the environment where the interactive smart tablet is located, and correct the target backlight brightness according to the illumination brightness.
S360、调整交互智能平板的背光亮度至目标背光亮度。S360, adjusting the backlight brightness of the interactive smart tablet to the target backlight brightness.
本实施例提供的技术方案,通过交互智能平板翻转后的当前角度值与翻转前的初始角度值的差值,确定对应的背光调节幅度后,根据背光调节幅度和初始背光亮度确定目标背光亮度,修正目标背光亮度并将交互智能平板的背光亮度调节至目标背光亮度的技术手段,实现了用户使用交互智能平板时根据角度值自动调节背光亮度,同时结合用户与交互智能平板的距离、交互智能平板所在环境的光照亮度等参数修正背光亮度,使得最终得到的背光亮度更加符合用户的实际需求,提升了用户的使用体验。 The technical solution provided by the embodiment determines the target backlight brightness according to the backlight adjustment amplitude and the initial backlight brightness, after determining the corresponding backlight adjustment range by the difference between the current angle value after the interactive smart tablet is flipped and the initial angle value before the flipping, The technical means of correcting the target backlight brightness and adjusting the backlight brightness of the interactive smart tablet to the target backlight brightness realizes that the user automatically adjusts the backlight brightness according to the angle value when using the interactive smart tablet, and combines the distance between the user and the interactive smart tablet, and interacts with the smart tablet. The brightness of the environment and other parameters correct the brightness of the backlight, so that the final brightness of the backlight is more in line with the actual needs of the user, which improves the user experience.
