The present invention provides a kind of video playing control method.Referring to Fig.1, Fig. 1 is video playing control method of the present invention the The flow diagram of one embodiment.

In the present embodiment, which includes:

Step S10 is obtained when the image for the video program that TV display interface plays is non-high dynamic range HDR image Take the image to be processed of the current video program；

Wherein, the image for the video program that its display interface of TV detecting real-time plays, and be non-in the image detected When high dynamic range HDR image, the image to be processed of the current video program is obtained.Preferably, in the present embodiment, TV can With the image to be processed of current video program described in timing acquisition, for example, current video program described in timing acquisition is to be processed The time interval of image can be 10ms, 15ms etc., to guarantee to carry out subsequent processing to each frame image, in addition, TV The pictorial information that will be played can be obtained directly in the corresponding video code flow of received video program, or is directly obtained Take the image that display interface is shown, in the present embodiment, TV directly acquires the image that its display interface is shown.

Step S20, determines whether the yield value of the image slices vegetarian refreshments to be processed meets preset condition；

In the present embodiment, each pixel of image to be processed passes through R/G/B (Red/Green/Blue, red green blue) Three Essential colour channels indicate that TV obtains the RGB yield value of image slices vegetarian refreshments to be processed, wherein the gain of each pixel Value is N (such as N=8) bit quantization, i.e. the numberical range of the R/G/B yield value of each pixel is 0~2⁸- 1, so The a certain yield value in RGB yield value is chosen afterwards as yield value to be adjusted, for example, choosing R yield value as gain to be adjusted Value, then judge whether the R yield value of image slices vegetarian refreshments to be processed meets preset condition, it is of course also possible to choose G yield value or Person's B yield value.Wherein, the selection of yield value to be adjusted can increase according to the RGB of image slices vegetarian refreshments to be processed in RGB yield value Beneficial value is selected, and for example, can choose R yield value as yield value to be adjusted for the image to be processed of red partially, for Partially green image to be processed can choose G yield value as yield value to be adjusted, can be with for partially blue image to be processed B yield value is chosen as yield value to be adjusted.

Wherein, preset condition includes that (preset range includes within a preset range for the yield value of pixel in picture to be processed First preset range and the second preset range) pixel number be greater than preset threshold, i.e., in the yield value in preset range When interior pixel number is greater than preset threshold, the yield value of the image slices vegetarian refreshments to be processed meets preset condition.With R gain For value, preset threshold determines that under normal circumstances, preset threshold can be set according to the total number of pixel in image to be processed Numberical range for 1/3, the R yield value of the total number of pixel in image to be processed is 0~255, in the first preset range Pixel is dark pixel point, since 1/3 or less the i.e. pixel yield value for being located at yield value range in pixel yield value is less than When 85, the lesser color of yield value is very dark, cannot achieve sublevel and shows, and then does not embody too strong clearly demarcated sense, therefore, the One preset range can be any range of the gain maximums such as 0~85,0~100 or 85~128 less than 128.Preferably, First preset range is the 1/3~1/2 of yield value range, specifically can be 85~128.Similar, the second preset range can be with It is greater than 128 any range for the gains minimum values such as 170~255,128~255 or 170~240, belongs in the second preset range Pixel be bright pixel point.Preferably, the second preset range is the 2/3~1 of yield value range, such as 170~255.

Step S30, when the yield value of the image slices vegetarian refreshments to be processed meets preset condition, in the image to be processed Show layers above increase transparent figure layer；

Wherein, transparent figure layer position identical with the pixel coordinate of image to be processed is transparent pixel, with Newly-increased transparent figure layer is avoided to influence the display of image to be processed.

Step S40, the coordinate based on each pixel in image to be processed successively obtain yield value and meet preset condition The yield value of two neighboring pixel in pixel；

Wherein, the yield value got is that yield value meets in preset condition coordinate phase in the pixel of same preset range The yield value of two adjacent pixels.

Step S50, when the difference of the two neighboring pixel yield value got every time is greater than the first preset difference value, base Pixel is added in the transparent figure layer in the yield value of two neighboring pixel, difference and coordinate.

In the present embodiment, TV corresponding position between two neighboring pixel coordinate of the transparent figure layer with image to be processed Set addition pixel, wherein the yield value of pixel is the gain mean value, and under normal circumstances, the number of pixel is not more than The difference.

When the image that the present embodiment passes through the video program played in TV display interface is non-HDR image, described in acquisition The image to be processed of current video program, then determines whether the yield value of the image slices vegetarian refreshments to be processed meets default item Part, then when the yield value of the image slices vegetarian refreshments to be processed meets preset condition, in the display figure of the image to be processed Layer top increases transparent figure layer, and it is default that the coordinate then based on each pixel in image to be processed successively obtains yield value satisfaction In condition in the pixel of same preset range two neighboring pixel yield value, it is finally two neighboring what is got every time When the difference of pixel yield value is greater than the first preset difference value, yield value, difference and coordinate based on two neighboring pixel exist Pixel is added in the transparent figure layer, by adding the pixel that pixel increases display in the transparent figure layer that newly increases Quantity, and can be avoided transparent figure layer and influence the display of image to be processed, improve the image quality and color of image of non-HDR image The clarity of details, and then the visual effect that user watches non-HDR video program is improved, improve user experience.

Wherein, the number of the pixel of addition is difference divided by gain fine granularity, under normal circumstances, takes difference divided by gain Fine-grained integer is the number of the pixel of addition.It, can be after the first coordinate corresponding pixel points when difference is positive number Pixel is successively increased, the yield value of pixel is added as the yield value of the first coordinate corresponding pixel points and successively subtracts gain particulate Degree adds the increasing of pixel alternatively, successively increasing the gain fine granularity pixel that subtracts one before the second coordinate corresponding pixel points Beneficial value is that the yield value of the second coordinate corresponding pixel points successively increases gain fine granularity；When difference is negative, the first coordinate pair It, can be after the first coordinate corresponding pixel points when answering yield value of the yield value of pixel less than the second coordinate corresponding pixel points The gain fine granularity pixel that subtracts one is successively increased, the yield value for adding pixel is the yield value of the first coordinate corresponding pixel points Gain fine granularity is successively increased, alternatively, successively increasing the gain fine granularity pixel that subtracts one before the second coordinate corresponding pixel points Point adds the yield value of pixel as the yield value of the second coordinate corresponding pixel points and successively reduces gain fine granularity, the present embodiment In, the number of the pixel of addition may be other values, such as addition pixel number be difference half, first When increasing pixel after coordinate corresponding pixel points, if the yield value of a certain pixel reaches the increasing of the second coordinate corresponding pixel points The yield value of pixel between the pixel and the second coordinate, then is disposed as the increasing of the second coordinate corresponding pixel points by benefit value Benefit value, when increasing pixel after the second coordinate corresponding pixel points, if the yield value of a certain pixel reaches the first coordinate pair The yield value of pixel is answered, then the yield value of the pixel and the pixel between the first coordinate is disposed as the first coordinate The yield value of corresponding pixel points.Certainly, in the present embodiment, the first coordinate and the second coordinate in transparent figure layer can also directly be covered Corresponding pixel, the yield value of the pixel of the first coordinate is the pixel of the first coordinate in image to be processed in transparent figure layer Yield value, the corresponding pixel of the second coordinate yield value be image to be processed in the second coordinate pixel yield value.

Further, in other embodiments, the coordinate of the two neighboring pixel includes that the first coordinate and second sit Mark, TV directly uniformly can add pixel between the first coordinate and the second coordinate of the transparent figure layer, wherein addition Pixel number be the difference half, the yield value of the pixel of addition is the gain mean value.

In the present embodiment, TV uniformly adds pixel between the first coordinate and the second coordinate of transparent figure layer, wherein The yield value of the pixel of addition is the gain mean value of two neighboring pixel yield value, the pixel of addition in the first coordinate and Be uniformly distributed between second coordinate, the distribution arrangement of pixel according to the yield value for successively obtaining two neighboring pixel side To, for example, under normal circumstances, the picture that the pixel of image is indicated according to wide * high, in particular to every a line of the picture (width) is included The number for the pixel that vegetarian refreshments number and each column (height) are included, is successively obtaining the yield value of two neighboring pixel Sequence is when obtaining according to capable direction, and the pixel of addition is uniform according to capable direction between the first coordinate and the second coordinate Distribution, when successively obtaining the sequence of yield value of two neighboring pixel is obtained according to the direction of column, the pixel of addition Be uniformly distributed between the first coordinate and the second coordinate according to the direction of column, two neighboring pixel be located at two different rows/ When column, corresponding pixel can be increased behind a wherein row (column) for transparent figure layer and before next row (column), when So, the pixel of the position can not also be increased.It is readily appreciated that, can also be with uneven distribution, under normal circumstances, the pixel of addition The number of point can sets itself according to demand, it is preferable that the number of the pixel of addition can be set to the half of difference, example Such as, when two adjacent pixels are respectively 210,218, the number of the pixel of addition is 4.

Further, in other embodiments, the number of the pixel of addition is that the half of the difference subtracts one, addition The yield value of pixel is that the smaller yield value in two neighboring pixel successively increases preset gain value.

In the present embodiment, the yield value of the pixel of addition is that the smaller yield value in two neighboring pixel successively increases Preset gain value, the number of the pixel of addition are that the half of the difference subtracts 1, in advance preferably, if yield value is 2, for example, When two adjacent pixels are respectively 210,218, the number of the pixel of addition is 3, the yield value of pixel is respectively 212, 214,216, when difference is odd number, for example, when two adjacent pixels are respectively 210,217, of the pixel of addition Number is 3, and the yield value of pixel is respectively 212,214,216.

In the present embodiment, if in image to be processed pixel yield value the first preset range (for example, 0~85) picture Vegetarian refreshments number be greater than preset threshold, and simultaneously in image to be processed the yield value of pixel in the second preset range (for example, 170 ~255) pixel number is greater than preset threshold, then can be based respectively on the yield value of the image slices vegetarian refreshments to be processed the Pixel is added in one transparent figure layer and the second transparent figure layer, specifically, preset threshold includes the first preset threshold and second Preset threshold, the yield value of pixel is greater than preset threshold in the pixel number of the first preset range in image to be processed When, when the difference of the two neighboring pixel yield value got every time is greater than the first preset threshold, obtain two neighboring picture The coordinate and gain mean value of vegetarian refreshments are added in the first transparent figure layer based on two neighboring pixel coordinate, difference and gain mean value Add pixel；The yield value of pixel is greater than preset threshold in the pixel number of the second preset range in image to be processed When, when the difference of the two neighboring pixel yield value got every time is greater than the second preset threshold, obtain two neighboring picture The coordinate and gain mean value of vegetarian refreshments are added in the second transparent figure layer based on two neighboring pixel coordinate, difference and gain mean value Add pixel.

Step S55 obtains the corresponding gain fine granularity of the difference when the difference is greater than the second preset difference value；

Wherein, the gain variation value for the pixel that gain fine granularity is added between two neighboring pixel, the present embodiment In, TV is stored with several difference ranges, such as (0,5), (6,10), (30,100) etc., equal for each difference range Equipped with corresponding gain fine granularity, therefore, when difference is greater than the second preset difference value, difference belonging to the available difference of TV It is worth the corresponding gain fine granularity of range.

Step S56, yield value and the gain fine granularity based on the first coordinate corresponding pixel points be calculated to Add the yield value of pixel；

Step S57, yield value and the difference based on the pixel to be added are sat the first of the transparent figure layer Pixel is uniformly added between mark and the second coordinate.
