具体实施方式Detailed ways
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本申请实施例的组件可以以各种不同的配置来布置和设计。In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of the present application, but not all of the embodiments. The components of the embodiments of the present application generally described and illustrated in the drawings herein may be arranged and designed in a variety of different configurations.
因此，以下对在附图中提供的本申请的实施例的详细描述并非旨在限制要求保护的本申请的范围，而是仅仅表示本申请的选定实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。Thus, the following detailed description of the embodiments of the application provided in the accompanying drawings is not intended to limit the scope of the application as claimed, but is merely representative of selected embodiments of the application.

相关技术中，用户与投影仪之间的交互方式仅限于通过遥控器对投影仪进行控制。相较于通过遥控器对电视机进行控制，两者在交互方式上，并没有实质性的区别，因此，目前投影仪提供的交互方式，并未结合投影仪本身的显示特点，导致未充分发掘投影仪的交互潜能，存在交互感欠佳等问题。In the related art, the interaction between the user and the projector is limited to controlling the projector through a remote control. Compared with the control of the TV through the remote control, there is no substantial difference between the two in terms of interaction. Therefore, the current interaction provided by the projector does not combine the display characteristics of the projector itself, resulting in insufficient exploration. The interactive potential of the projector has problems such as poor interaction.
鉴于此，本申请实施例提供一种图像显示方法，应用于投影仪。由于投影仪的显示原理是通过镜头将图像画面投射到显示介质，使得用户可以通过显示介质观看到图像画面。该图像显示方法中，投影仪针对至少一种类型待显示画面配置有对应的投影方式，以充分利用投影仪投影方式可变的特点，提供更多交互及显示方式。In view of this, embodiments of the present application provide an image display method, which is applied to a projector.

其中，该存储器120、处理器130以及通信装置140各元件相互之间直接或间接地电性连接，以实现数据的传输或交互。例如，这些元件相互之间可通过一条或多条通讯总线或信号线实现电性连接。The elements of the memory 120 , the processor 130 and the communication device 140 are directly or indirectly electrically connected to each other to realize data transmission or interaction. For example, these elements may be electrically connected to each other through one or more communication buses or signal lines.
其中，该存储器120可以是，但不限于，随机存取存储器(Random Access Memory，RAM)，只读存储器(Read Only Memory，ROM)，可编程只读存储器(Programmable Read-Only Memory，PROM)，可擦除只读存储器(Erasable Programmable Read-Only Memory，EPROM)，电可擦除只读存储器(Electric Erasable Programmable Read-Only Memory，EEPROM)等。其中，存储器120用于存储程序，该处理器130在接收到执行指令后，执行该程序。Wherein, the memory 120 can be, but not limited to, random access memory (Random Access Memory, RAM), read only memory (Read Only Memory, ROM), programmable read only memory (Programmable Read-Only Memory, PROM), Erasable Programmable Read-Only Memory (EPROM), Electric Erasable Programmable Read-Only Memory (EEPROM), etc. The memory 120 is used for storing a program, and the processor 130 executes the program after receiving the execution instruction.
该处理器130可能是一种集成电路芯片，具有信号的处理能力。上述的处理器可以是通用处理器，包括中央处理器(Central Processing Unit，简称CPU)、网络处理器(Network Processor，简称NP)等；还可以是数字信号处理器(DSP)、专用集成电路(ASIC)、现场可编程门阵列(FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件。可以实现或者执行本申请实施例中的公开的各方法、步骤及逻辑框图。通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等。The processor 130 may be an integrated circuit chip with signal processing capability.

A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
请参照图2，图2为应用于图1所示的投影仪的图像显示方法的流程图，以下将对该方法包括各个步骤进行详细阐述。其中，该投影仪针对至少一种类型的待显示画面配置有对应的投影方式。如图2所示，该图像显示方法包括：Please refer to FIG. 2 . FIG. 2 is a flowchart of an image display method applied to the projector shown in FIG. 1 , and each step of the method will be described in detail below. Wherein, the projector is configured with a corresponding projection mode for at least one type of picture to be displayed. As shown in Figure 2, the image display method includes:
步骤S101，获取待显示画面以及待显示画面的类型。Step S101, acquiring the picture to be displayed and the type of the picture to be displayed.
步骤S102，将与待显示画面的类型相对应的投影方式，作为目标投影方式。In step S102, the projection mode corresponding to the type of the picture to be displayed is used as the target projection mode.
步骤S103，将待显示画面以目标投影方式进行显示。In step S103, the to-be-displayed picture is displayed in the target projection mode.
该投影方式可以是镜头焦距调整、镜头角度调整以及图像明暗调整中的至少一种，或者其组合。The projection method may be at least one of lens focal length adjustment, lens angle adjustment, and image brightness adjustment, or a combination thereof.
上述方式中，基于投影仪的显示原理，投影仪针对待显示画面，将与待显示画面的类相对应的投影方式，作为目标投影方式，并以目标头投影方式显示该待显示画面。相较于通过固定不变的投影方式显示画面，该投影仪基于待显示画面的类型，以对应的投影方式显示该待显示画面，充分利用投影仪投影方式可变的特点，提供了更多的交互及显示方式。In the above method, based on the display principle of the projector, the projector uses the projection method corresponding to the type of the to-be-displayed image as the target projection method for the to-be-displayed image, and displays the to-be-displayed image in the target head projection method. Compared with displaying the picture through a fixed projection method, the projector displays the picture to be displayed in a corresponding projection method based on the type of the picture to be displayed, making full use of the variable projection method of the projector, and provides more interaction and display.
相关投影方式中，只是单纯的将视频源中的画面投影到显示介质中，并不会对显示内容产生相应的反馈，因此，难以提供震撼的画面效果以及沉浸的观感体验。In the related projection method, the picture from the video source is simply projected onto the display medium, and no corresponding feedback is produced on the display content. Therefore, it is difficult to provide a shocking picture effect and an immersive viewing experience.
鉴于此，本申请实施例中，该投影仪获取待显示画面和/或待显示画面对应的音频，并对待显示画面和/或音频进行识别，判断出待显示画面的类型。In view of this, in the embodiment of the present application, the projector acquires the picture to be displayed and/or the audio corresponding to the picture to be displayed, and identifies the picture to be displayed and/or the audio to determine the type of the picture to be displayed.
例如，该待显示画面可以是，但不限于，动作画面、气氛较为温馨画面、气氛较为紧张的画面等。For example, the to-be-displayed picture may be, but not limited to, an action picture, a picture with a warm atmosphere, a picture with a relatively tense atmosphere, and the like.
本申请实施例中，将动作画面以及与动作画面相类似的画面归类为第一类型。例如，该第一类型的画面还可以是炸弹***的画面等。如图3所示，该投影仪检测到待显示画面的画面内容为第一类型时，可以在显示该待显示画面时，在第一调整范围内调整增大镜头的焦距，并将焦距恢复原样。In the embodiment of the present application, the action pictures and pictures similar to the action pictures are classified as the first type. For example, the picture of the first type may also be a picture of a bomb explosion or the like. As shown in FIG. 3 , when the projector detects that the content of the image to be displayed is of the first type, it can adjust the focal length of the lens within the first adjustment range when displaying the image to be displayed, and restore the focal length to the original .
其中，值得说明的是，该投影仪通过电机驱动特定的机械结构，以实现投影机焦距的调整。相对应的，该电机驱动的驱动速度决定了焦距调整 的速度，具体表现为投影区域200的变化速度。因此，本领域技术人员可以根据实际需求，适应性调整该电机驱动的驱动速度，其基于本申请实施例不需要做出创造性的贡献。Among them, it is worth noting that the projector drives a specific mechanical structure through a motor to realize the adjustment of the focal length of the projector. Correspondingly, the driving speed driven by the motor determines the speed of focal length adjustment, which is specifically expressed as the changing speed of the projection area 200. Therefore, those skilled in the art can adaptively adjust the driving speed of the motor drive according to actual needs, which does not need to make creative contributions based on the embodiments of the present application.
由于镜头的焦距的变化，会导致投影区域200的尺寸产生变化，使得投影区域200呈现由小变大，由大变小的效果(图3中虚线部分为尺寸变大后的投影区域)，继而可以给用户营造打斗非常激烈的沉浸体验感。Due to the change of the focal length of the lens, the size of the projection area 200 will change, so that the projection area 200 exhibits the effect of changing from small to large, and from large to small (the dotted line in FIG. 3 is the projected area after the size has increased), and then It can create a very intense immersive experience for users.
同理，本申请实施中，还包括其他类型的待显示画面。将震动类型的画面归类为第二类型。如图4所示，该投影仪检测到待显示画面的画面内容为第二类型(例如，画面内容为地震)，可以在预设角度范围内上下调整镜头的角度后，将镜头的角度恢复原样。由于上下调整镜头的角度，会导致投影区域200上下抖动(图4中虚线部分为上下抖动后的投影区域)，可以给用户模拟出震动的沉浸体验感。Similarly, in the implementation of this application, other types of to-be-displayed pictures are also included. The vibration type picture is classified as the second type. As shown in FIG. 4 , the projector detects that the content of the picture to be displayed is of the second type (for example, the content of the picture is earthquake), and after adjusting the angle of the lens up and down within the preset angle range, the angle of the lens can be restored to the original state . Adjusting the angle of the lens up and down will cause the projection area 200 to shake up and down (the dotted line in FIG. 4 is the projection area after shaking up and down), which can simulate a vibrating immersive experience for the user.
本申请实施例中，作为一种可能的实现方式，为了使得投影仪能够识别出待显示画面的类型，该投影仪配置有与训练的机器学习模型。投影仪通过该机器学习模型对待显示画面和/或待显示画面对应的音频进行识别，判断出待显示画面的类型。In the embodiment of the present application, as a possible implementation manner, in order to enable the projector to identify the type of the picture to be displayed, the projector is configured with a trained machine learning model. The projector identifies the picture to be displayed and/or the audio corresponding to the picture to be displayed through the machine learning model, and determines the type of the picture to be displayed.
为了获得该预训练的机器学习模型，该投影仪获取样本图像，其中，各样本图像标记有对应显示画面的类型；通过样本图像训练预设机器学习模型识别样本图像中显示画面的类型，获得预训练的机器学习模型。In order to obtain the pre-trained machine learning model, the projector obtains sample images, wherein each sample image is marked with the type of the corresponding display screen; the preset machine learning model is trained by the sample images to identify the type of the display screen in the sample image, and the pre- Trained machine learning model.
示例性的，以上述第一类型的画面为例，可以收集大量打斗内容的视频片段作为视频样本，对应的音频作为音频样本，用于训练机器学习模型对画面内容进行识别，获得预训练的机器学习模型。因此，当待显示画面为第一类型的画面时，机器学习模型能够根据显示画面的画面内容和/或显示画面对应的音频，对其进行识别。应理解的是，打斗内容的视频对应的音频中携带的打斗声，可以用于提高对显示画面的识别率。当然，本申请实施例可以结合多种类型的样本图像进行训练，使得预先训练的机器学习 模型能够识别出多种显示画面。Exemplarily, taking the above-mentioned first type of picture as an example, a large number of video clips of fighting content can be collected as video samples, and the corresponding audio can be used as audio samples, which are used to train a machine learning model to identify the picture content and obtain a pre-trained machine. Learning models. Therefore, when the picture to be displayed is a picture of the first type, the machine learning model can identify it according to the picture content of the displayed picture and/or the audio corresponding to the displayed picture. It should be understood that the fighting sound carried in the audio corresponding to the video of the fighting content can be used to improve the recognition rate of the displayed picture. Of course, the embodiment of the present application can be trained in combination with various types of sample images, so that the pre-trained machine learning model can identify various display images.
本申请实施例中，考虑到上述投影方式的变化，不能影响到画面显示的流程度。因此，该投影仪配置有视频缓存区域，视频缓存区域用于缓存待显示画面。即视频缓存区域缓存的待显示画面为需要显示的画面数据，并从中选取待显示画面进行显示。In the embodiment of the present application, considering the change of the above-mentioned projection mode, the flow degree of the screen display cannot be affected. Therefore, the projector is configured with a video buffer area, and the video buffer area is used for buffering the picture to be displayed. That is, the to-be-displayed picture buffered in the video buffer area is the picture data to be displayed, and the to-be-displayed picture is selected and displayed.
因此，该投影仪建立待显示画面与目标投影方式之间的对应关系，并在显示到待显示画面时，根据上述对应关系确定目标投影方式；将待显示画面以目标投影方式进行显示。Therefore, the projector establishes a corresponding relationship between the to-be-displayed picture and the target projection mode, and when the to-be-displayed picture is displayed, the target projection mode is determined according to the above-mentioned correspondence; the to-be-displayed picture is displayed in the target projection mode.
由于识别获取待显示画面的类型，需要一定的计算时间，因此，本申请实例中，针对视频缓存区域中的待显示画面，在显示之前，建议其对应的目标投影方式，继而能够减少确定待显示画面的类型对流畅度的影响。Since it takes a certain amount of calculation time to identify and obtain the type of the picture to be displayed, in the example of this application, for the picture to be displayed in the video buffer area, before displaying the picture to be displayed, the corresponding target projection mode is suggested, which can reduce the number of times to determine the to-be-displayed picture. The effect of the type of screen on the fluency.
其他相关技术中，用户仅能够通过遥控器对投影仪进行预设功能的操作，并且在操作过程所显示画面的画面效果，由提供该显示画面的应用程序决定。因此，导致用户缺乏对投影仪的交互感。In other related technologies, the user can only operate the projector with preset functions through the remote control, and the image effect of the displayed image during the operation is determined by the application program that provides the displayed image. Therefore, the user lacks a sense of interaction with the projector.
因此，本申请实施例中，作为另外一种可能的实现方式，该投影仪响应于待显示画面中的交互操作，获得待显示画面、交互操作在待显示画面中的交互位置以及交互操作的操作方式；基于待显示画面的显示内容，根据操作方式以及交互位置，确定待显示画面的类型。Therefore, in this embodiment of the present application, as another possible implementation manner, the projector, in response to the interactive operation in the to-be-displayed image, obtains the to-be-displayed image, the interactive position of the interactive operation in the to-be-displayed image, and the operation of the interactive operation mode; based on the display content of the to-be-displayed image, the type of the to-be-displayed image is determined according to the operation mode and the interactive position.
示例性的，当前显示画面可以是视频APP选择界面，基于该APP选择界面，投影仪根据用户在该APP选择界面中的交互位置以及交互操作，确定用户在一目标APP的标识位置按下了确定按钮，即用户打开了该目标APP。即接下来的画面为该APP的启动画面，本申请实施例中，将这一类的画面归类为第三类型。Exemplarily, the currently displayed screen may be a video APP selection interface. Based on the APP selection interface, the projector determines that the user has pressed OK at the identification position of a target APP according to the user's interactive position and interactive operation in the APP selection interface. button, that is, the user opens the target APP. That is, the next screen is the startup screen of the APP. In the embodiment of the present application, this type of screen is classified as the third type.
针对第三类型的画面，为了提供更强的交互感，该投影仪先在第二调整范围内缩小焦距，使得投影区域缩小，接着调整镜头的焦距，使得投影区域恢复到原样。此时，该投影仪通过上述方式，给用户提供投影区域由 小到大的过度动画，模拟出“打开”的效果。For the third type of picture, in order to provide a stronger sense of interaction, the projector first reduces the focal length within the second adjustment range to reduce the projection area, and then adjusts the focal length of the lens to restore the projection area to the original. At this time, the projector provides the user with an excessive animation of the projection area from small to large in the above-mentioned manner, simulating the effect of "turning on".
并且，上述投影区域的效果由投影仪提供，不受具体视频APP的限制，因此，能够适应不同种类的视频APP。In addition, the effect of the above-mentioned projection area is provided by the projector and is not limited by a specific video APP, so it can be adapted to different types of video APPs.
