IMAGE SENSOR AND SENSOR MODULE

摘要

According to one aspect of the present invention, an image sensor and a sensor module have a configuration in which the image sensor outputs first brightness information representing brightness information of first image information obtained with a first exposure time and second brightness information representing brightness information of second image information obtained with a second exposure time separately from a composite image obtained by synthesizing the first image information and the second image information, updates the first and second exposure times based on an exposure time set value externally generated based on the first brightness information and the second brightness information, and changes a synthesis set value used for synthesis of the composite image based on the exposure time set value externally generated based on the first brightness information and the second brightness information.

1. An image sensor comprising:
a pixel array that outputs image information based on incident light information; a pixel control unit that controls an exposure time for pixels arranged in the pixel array; a first brightness information generation unit that generates first brightness information from first image information generated based on incident light information obtained by the pixel array with a first exposure time; a second brightness information generation unit that generates second brightness information from second image information generated based on incident light information obtained by the pixel array with a second exposure time shorter than the first exposure time; and an image synthesizing unit that synthesizes the first image information and the second image information and outputs a composite image, wherein the pixel control unit updates the first exposure time and the second exposure time based on an exposure time set value generated outside the pixel control circuit based on the first brightness information and the second brightness information, and the image synthesizing unit updates conditions for synthesizing the first image information and the second image information based on a synthesis set value generated outside the image synthesizing unit based on the first brightness information and the second brightness information.
