Abstract
A depth estimation system can enhance depth estimation using brightness image. Light is projected onto an object. The object reflects at least a portion of the projected light. The reflected light is at least partially captured by an image sensor, which generates image data. The depth estimation system may use the image data to generate both a depth image and a brightness image. The image sensor includes a plurality of pixels, each of which is associated with two ADCs. The ADCs receive different analog signals from the pixel and outputs different digital signals. The depth estimation system may use the different digital signals to determine the brightness value of a brightness pixel of the brightness image. The ADCs may be associated with one or more other pixels. The pixel and the one or more other pixels may be arranged in a same column in an array of the image sensor.
