Embodiment Construction

[0058] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0059] Such as figure 1 As shown, an image display driving method comprises the following steps:

[0060] ① Input image: input an image in RGB format, obtain the grayscale of R, G, and B from each pixel unit of the RGB format image, and convert it into YUV format according to the conversion formula, and the conversion formula is:

[0061]

[0062] Among them, Y is the brightness component, U and V are the color difference components, G is the green component, B is the blue component, and R is the red component;

[0063] ② Obtain the brightness component Y: obtain the brightness component Y from the image in YUV format;

[0064] ③ Calculate the average brightness and maximum brightness: Calculate the average brightness and maximum brightness of all pixel units in the YUV format image, the average brightness Y av The calculatio...

Abstract

The invention provides an image display drive method, and the method comprises the following steps: inputting an image; obtaining a brightness component; calculating the mean brightness and the maximum brightness; constructing a segmented linear model; and updating a brightness component. The segmented linear model proposed by the invention just need to perform the linear calculation without the square calculation, thereby reducing the hardware implementation complexity while improving the performances. A mean value of brightness is selected as a segmentation point of low-power-consumption processing, wherein the image details less than the value remain unchanged and the low-power-consumption processing of the remaining parts is performed according to the segmented linear model, thereby reducing the display power consumption while maintaining the visual effect. The display power consumption for processing the obtained image is the minimum under the condition that the visual effect remains unchanged, and the visual effect, compared with NPC and ACSC, is improved by 32.3% and 28.7%.

Description

technical field [0001] The invention relates to an image display driving method, which belongs to the field of image enhancement and the technical field of consumer electronics. Background technique [0002] At present, although smart phones have powerful functions, due to high power consumption, the charging frequency is relatively high, usually once a day, which brings great inconvenience to people's lives. According to statistics, 50% of the power consumption of smart phones is consumed on the display screen. Therefore, reducing the power consumption of the display screen is the key to solving the above problems. [0003] In recent years, many literatures have proposed low-power image display driving methods, such as literature (A.Arkhipov, B.W.Lee, K.Park, S.D.Sung, S.Shin, and K.Chung, "Using Net Power Control for AMOLED TV," in IMID, Daegu, Korea, 2007, pp.47-50) proposed a power consumption control algorithm (NPC), if the total current is greater than the threshold c...
