Image Enhancement Technique Based on Sub Row Driving Human Visual

The technology principle of sub-row driving gray-scale modulation is introduced and is used in FED. In order to satisfy the demand of the chip driving high-speed of the SRD method, some image data bits are reduced, while the application of error diffusion method is used to achieve image restoration. Error-diffusion method reproduces the image detail better and reduces distortion phenomenon, but will reduce the gray-scale and overall contrast. According to the human visual characteristics, the image enhancement technology based on human visual is proposed to improve the video image quality, and applied to the sub-row driving of FED, and makes the contrast of the video image increased, makes the image quality more delicated and closer to the human visual effect.
