Problems solved by technology

Since this image adjustment curve 110 is a quadratic curve, it is computationally more complicated to implement.
Although the linear image adjustment curve has better performance, the hardware cost of implementation is higher, and the dual considerations of cost and performance cannot be taken into account.

Embodiment Construction

[0038] Please refer to figure 2 , figure 2 A schematic diagram of a display device 200 according to an embodiment of the present invention is shown. The display device 200 includes an image statistics module 210 , a parameter calculation module 220 and an image adjustment module 230 . Wherein, the image statistics module 210 receives a plurality of image data DIN, and calculates the number of pixels corresponding to different brightness in the image data DIN, so as to obtain the brightness distribution parameter HIS. To be more specific, the image statistics module 210 calculates the total number of pixels corresponding to displaying different luminances in a plurality of image data DIN. Please refer to Figure 2A A histogram of the brightness distribution parameter 250 is shown. Wherein, the horizontal axis of the brightness distribution parameter 250 bar graph is the brightness, and the vertical axis is the total number of pixels corresponding to each brightness. Taki...

Abstract

The invention relates to a display device. The display device comprises an image statistical module, a parameter calculation module and an image adjusting module, wherein the image statistical module is used for receiving a plurality of image data and calculating the pixel number corresponding to different kinds of luminance in the image data so as to acquire luminance distribution parameters; the parameter calculation module is used for searching set luminance of which the emergence probability is in a first specific proportion according to the luminance distribution parameters, searching first and second adjusted luminance of which the emergence probabilities are is in a second specific proportion and a third specific proportion according to the luminance distribution parameters and calculating a piece-wise linear luminance corresponding relation according to the set luminance, the first adjusted luminance and the second adjusted luminance; when input image data are equal to the set luminance, output image data are equal to input image data; and the image adjusting module is used for adjusting the image data according to the luminance corresponding relation so as to generate a plurality of display image data. The display device can simply and effectively achieve an effect of dynamically adjusting display image contrasts.

Description

technical field [0001] The present invention relates to a display device, and in particular to a device for adjusting the display image contrast of the display device. Background technique [0002] Today, with the increasing popularity of electronic technology, electronic products have become an indispensable tool in people's lives. In order to provide users with better quality of use, a high-performance display device is an indispensable and necessary equipment for today's electronic products. [0003] In order to improve the display performance of the display device, image contrast adjustment is a very important function. However, in the known technical field, in the case of ignoring the display content of the image, only a single straight-line image adjustment curve of the corresponding relationship between the brightness of the input image data and the output image data is proposed as the basis for image contrast adjustment. This linear image adjustment curve is of cou...
