Abstract

In this paper, a flexible analog gamma correction technology has been proposed. In order to represent images on modern display systems with proper contrast, gamma correction is required to encode these input images. Conventional gamma corrections are performed in the digital domain. However, due to the limitation of the ADC resolution, the image quality with low level luminance is significantly degraded. In this proposed method, the adjustment of the implementation for the gamma correction in a design flow integrates this image processing with A/D conversion at the same time. By this approach, the quantization noise of the ADC is not amplified by gamma correction. Furthermore, the hardware area and power consumption can be reduced.
