Patent ID: 8254688

Claim:
An image pickup system comprising: an image pickup device having a photodetecting section with a plurality of pixels arranged two-dimensionally therein, said image pickup device outputting image data that represents the two-dimensional intensity distribution of light incident on said photodetecting section, and outputting light intensity profile data that represents the one-dimensional intensity distribution of the incident light in each of a first direction and a second direction different from the first direction in said photodetecting section; a peak position detecting section acquiring the light intensity profile data in the respective first and second directions outputted from said image pickup device and detecting a light intensity peak position in the two-dimensional intensity distribution of the light incident on said photodetecting section in said image pickup device based on the acquired light intensity profile data; a partial image acquiring section acquiring a partial image from an entire image that can be imaged by the image pickup device so that the light intensity peak position detected by said peak position detecting section is made a specific position for the partial image in the entire image; and a partial image operating section integrating the partial image acquired by said partial image acquiring section.
