Abstract:
1. An image processing system comprising: an image sensor configured to convert an optical image signal into electrical image data and output frame data, the image sensor including an analog-to-digital converter and a timing generator, the analog-to-digital converter configured to convert the optical image signal into the electrical image data such that the electrical image data is a digital representation of the optical image signal having a gain associated therewith, and the timing generator is configured to control the gain of the analog-to-digital converter in response to a brightness control signal; and an image signal processor configured to receive the frame data, calculate an average brightness of a frame defined by the frame data, and output the brightness control signal to control a brightness of a next frame based on the average brightness, such that the brightness of a next frame data output by the image sensor is adjusted in response to the brightness control signal.
