Detailed Description
The invention provides a peak brightness improving method, a storage medium and a smart television, and in order to make the purpose, technical scheme and effect of the invention clearer and clearer, the invention is further described in detail below by referring to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the present invention, suffixes such as "module", "part", or "unit" used to indicate elements are used only for facilitating the description of the present invention, and have no specific meaning in themselves. Thus, modules, components, or units may be used mixedly.
The terminal device may be implemented in various forms. For example, the terminal described in the present invention may include a mobile terminal such as a mobile phone, a smart phone, a notebook computer, a digital broadcast receiver, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, and the like, and a stationary terminal such as a digital TV, a desktop computer, and the like. However, it will be understood by those skilled in the art that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to elements particularly used for moving purposes.
The invention will be further explained by the description of the embodiments with reference to the drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for increasing peak luminance according to a preferred embodiment of the present invention. The method comprises the following steps:
s100, when an HDR film source is received, judging the type of the HDR film source, wherein the type comprises a static HDR film source and a dynamic HDR film source;
s200, if the type is a static HDR film source, identifying a brightness region of the HDR film source;
s300, acquiring a gray value of the brightness area, and comparing the gray value with a preset target value;
s400, if the gray value is larger than a preset target value, the driving current corresponding to the brightness area is increased, so that the brightness of the brightness area reaches a preset peak value brightness.
This embodiment provides a method for increasing peak luminance, which first determines a type of an HDR source when the HDR source is received, and obtains a brightest region of the HDR source as a luminance region when the HDR source is static, and calculates a gray value of the luminance region, and increases a driving current corresponding to the luminance region if the gray value reaches a preset target value, so that the luminance of the luminance region reaches peak luminance. Therefore, the brightness can reach the peak brightness on the basis of not increasing the cost of the intelligent television, and meanwhile, the power of the intelligent television can be reduced.
Specifically, in step S100, before receiving the HDR film source, it is required to monitor whether there is an input signal at the input end of the smart television, and if there is no signal source input, the signal source detection is continued. When a signal source is input, whether the signal source is an SDR film source or an HDR film source is judged.
Exemplarily, when receiving the HDR source, the determining the type of the HDR source further includes:
s01, detecting a chip source signal input by a signal input end, and detecting whether the chip source signal carries a flag bit;
s02, if the HDR film source signal carries a flag bit, determining that the film source signal is an HDR film source.
Specifically, the flag is included in a header file of the HDR film source, and may specifically include three features, which are a Color space standard adopted by original Color information (Color primaries), a standard adopted by peak luminance (transfer characteristics), and luminance nonlinearity (matrix coefficients), respectively. After decoding a slice source signal input by a digital signal input interface, detecting the three characteristics, and judging whether the slice source information is an HDR slice source or an SDR slice source according to the three characteristics. In this example, the slice source signal is determined to be an HDR slice source by detecting and determining whether the values of the three features satisfy a preset condition. For example, the values of the three features are: color primaries have a value of 9, representing a Color space standard of bt.2020; the Transfer Characteristics value is 16, representing a brightness standard of SMPTE ST 2084. If the value of matrix coeffients is 9 and the linear relation representing luminance information is the BT.2020NCL standard, the signal slice source is determined to be an HDR slice source, and if the value is not the above characteristic value, the signal slice source is determined to be an SDR slice source.
Further, in step S200, the luminance region refers to the brightest region in the HDR picture source, and the luminance of the luminance region extracts a peak luminance pixel point or a peak luminance region of the entire picture according to a luminance signal of a pixel point in the HDR picture source image. In this embodiment, the brightness of the brightness region refers to an average brightness of the brightness region, that is, the image is divided into a plurality of regions, an average value of brightness information of each currently divided region is calculated to obtain an average brightness of each region, and the brightness region is determined according to the average brightness. The number of regions may be 12 × 1 regions, but in practical applications, in order to improve the accuracy of selecting the brightness regions, the regions may be divided into more regions, for example, 12 × 3 regions.
For example, if the type is a static HDR source, identifying the luminance region of the HDR source specifically includes:
s201, if the type is a static HDR film source, dividing the HDR film source into a plurality of regions, and calculating the average brightness of each region;
s202, determining a brightness region of the HDR film source according to the average brightness.
Specifically, the calculating the average brightness of each region may be: in each region, the brightness information of all the pixel points is added and then divided by the total number of the pixel points to obtain the brightness average value of the region. The determining the brightness region of the HDR picture source according to the average brightness refers to comparing the brightness average values of each region, finding out a region with the largest brightness average value, and selecting the region with the largest average value as the brightness region. In practical application, the maximum value and the average value of the brightness of each area are obtained, and the brightness value of each area is obtained by combining a spatial filter and a time filter, so that backlight flicker caused by movement of a high-brightness object can be reduced by the spatial filter, the brightness of the central position is improved, the time filter is used for controlling brightness change of the backlight, and the display effect of an image after driving current adjustment is improved.
In step S300, the image-based decoded image includes a gray value, which is expressed by an 8-ary system, and the range of the gray value is 8 powers of 2, i.e. 0 to 255, that is, each pixel corresponds to one of 0 to 255 to express the gray value. And acquiring gray values of all pixel points in the brightness area, comparing the gray values of all the pixel points to determine the maximum value of the pixel points, and comparing the maximum value with a preset target value. The target value is preset, for example, 255, 250, etc. In practical application, when the gray value of only one pixel is larger than a preset target value, the pixel point is a peak brightness point; and when the gray value of the plurality of pixel points is larger than a preset target value, the plurality of pixel points are adjacent to each other to form a peak brightness area.
In step S400, in the case of a static HDR10 image, after the gray scale value is larger than the preset target value, the range of the white field of the HDR picture source is determined, and it is further determined whether or not the driving current needs to be increased.
For example, if the gray-level value is greater than a preset target value, increasing the driving current of the HDR sheet source to make the luminance of the luminance region reach a preset peak luminance specifically includes:
s401, if the gray value is larger than a preset target value, acquiring the proportion of a white field in the HDR film source, and judging whether the proportion is in a preset range;
s402, if the brightness is within the preset range, adjusting the driving current of the brightness area to a preset current threshold value so that the brightness of the brightness area reaches a preset peak brightness.
Specifically, the preset range is 10% to 15%, that is, a white field of 10% to 15% is used as a boosting condition, and when a region of the white field is between 10% to 15%, a driving current of the backlight driving circuit corresponding to the luminance region is raised to a preset current threshold. The preset current threshold is preferably 200mA, and the peak brightness is above 1000nit for a gray scale of 255 corresponding to 0XFF in hexadecimal. In practical applications, the process of raising the current may be to raise the current to 200mA for 10 seconds when the authentication signal of the WieHDR10 is input, and then to lower the current to the normal state of 120mA for 3 minutes, which are sequentially cycled. Therefore, the requirement of HDR peak brightness can be met, and the energy consumption of the intelligent television is reduced.
Further, the driving current is a constant current driving current, when a white field of 10% -15% is satisfied, the driving current of the backlight driving circuit corresponding to the luminance region is increased, and for the driving current of other regions, a default driving current may be used, or corresponding adjustment may be performed according to a relationship between the default driving current and the luminance value of the luminance region. For example, the drive current is adjusted in proportion to the luminance value, and the like.
In this embodiment, the smart television adopts 12-zone edge-lit backlight control, that is, 12 groups of backlight driving circuits of the backlight driving control module, and the 12 groups of backlight driving circuits correspondingly control the backlight light bars in the 12 zones. Correspondingly, if the luminance area is within the preset range, the driving current of the luminance area is adjusted to a preset current threshold value, so that the luminance of the luminance area reaches a preset peak luminance, specifically, a partition corresponding to the luminance area is obtained first, and then the driving current of the backlight light bar corresponding to the partition is provided through the backlight driving circuit corresponding to the partition, so as to provide the luminance of the luminance area, so that the pixel point or the pixel area with the maximum gray value in the luminance area reaches the maximum peak luminance.
In an embodiment of the present invention, the method for increasing peak brightness of a smart television further includes:
s500, when the type is a dynamic HDR film source, dividing the HDR film source into a plurality of areas;
s600, acquiring the number of the white fields in the plurality of areas, and comparing the number with a preset number threshold;
s700, when the number is smaller than a preset threshold value, adjusting the driving current of the HDR film source according to a preset rule.
Specifically, the white field means that the gray value of the region is greater than a preset threshold, and correspondingly, the obtaining of the number of the white fields in the plurality of regions and the comparing of the number with the preset number threshold specifically include: firstly, respectively calculating the average gray scale of the plurality of regions, and comparing the average gray scale with a preset threshold value; and counting the number of the areas with the average gray scale larger than a preset threshold, recording the areas as the number of white fields, and comparing the number with the preset number threshold, wherein the preset number threshold is preferably 6.
Further, to illustrate the preset rule, as shown in table one, it is assumed that dream _ right is the number of areas with the average gray-scale value PWM larger than the preset threshold F0, and when the average gray-scale value of an area is larger than F0, the area is considered as a white field. Here, 12 partitions are taken as an example, and when the drain _ right is 12, it is considered as a full white field. When 12> dream _ right >6, the target current is not increased when the number of the white field areas is more than 6, and when 6> dream _ right >4, the current value of the increased target is 144 mA; when 4> dream _ right >2, the current value of the lifting target is 148 mA; when 1> dream _ right >1, the current value of the lifting target is 153 mA; when 0> dream _ right >0, the current value of the boosting target is 162 mA. In practical applications, the adjusting of the driving current may control the backlight driving circuit to output different driving currents by adjusting a hexadecimal value of a control signal sent to the driving circuit of the backlight module. For example, the backlight driving circuit driving current I is 120mA, the control signal received by the backlight driving circuit is hexadecimal register value 0X4F, the backlight driving circuit driving current I is 170mA, the control signal received by the light driving circuit is hexadecimal register value 0X5C, the backlight driving circuit driving current I is 200mA, and the control signal received by the light driving circuit is hexadecimal register value 0XB 9.

Further, a data rule that the backlight driving and controlling circuit receives a control signal is preset, the control signal comprises current data and check bits of 2 bytes, 8 bits in the 2 bytes represent the current, and 8 bits in the 2 bytes represent the current gray value of the backlight. For example, the control signals include: data1, Data2, Data3, Data4, Data5, Data6, Data7 and Data8 at the upper 8-bit position; the low-order 8 bits are Data9, Data10, Data11, Data12, Data13, Data14, Data15 and Data16, and check bits at the front end and the back end of the Data byte.
In an embodiment of the invention, while the driving current is increased, it is required to ensure that the power of the LED light bar corresponding to the driving current meets the rated power, so that the service life of the LED light bar is not affected. Correspondingly, when the number is smaller than the preset threshold, adjusting the driving current of the HDR chip source according to the preset rule specifically includes:

and S803, when the output power is less than or equal to the rated power, adjusting the driving current of the brightness region to the first driving current.
In yet another embodiment of the present invention, the ratio of the white field area corresponding to the static HDR film source is 10% -15% in the preset range, that is, the ratio of the white field area is 0-10% or 15% -100%, and a normal driving current value, that is, 12mA, may be adopted for the static HDR film source; the adjustment may also be performed by using an adjustment method of the dynamic HDR picture source, which is not described here.
