Embodiment Construction
[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0050] see figure 1 , is a schematic diagram of the modules of the dynamic contrast enhancement device in the preferred embodiment of the present invention. Such as figure 1 As shown, the dynamic contrast enhancement device provided by this embodiment at least includes: a color space conversion module 10 , a histogram statistics module 20 , an enhancement mapping function module 30 and a brightness transformation module 40 .
[0051] Among them, the color space conversion module 10 is used to convert the input image data from RGB color space to YUV color space, and can convert the contrast-enhanced data from YUV color space back to RGB color space for output.
[0052] The histogram statistics module 20 is used for statistics of the grayscale hist...
