SOLID-STATE IMAGE PICKUP DEVICE

摘要

A solid-state image pickup device 1A includes an image pickup section 2 having a pixel array P in which a pixel C is two-dimensionally arranged, a lens section 3 having a plurality of lenses 3a arranged on the pixel array P, and an image generating section 4A for generating an image by using an electrical signal SE. The image pickup section 2 has a plurality of the pixel arrays P including one image pickup region T. The image generating section 4A generates the image by averaging the electrical signals SE for each pixel C corresponding to one another among the image pickup regions T, in order to reduce noise present in the electrical signal SE.

1. A solid-state image pickup device, comprising:
an image pickup section having a pixel array in which pixels for providing, via a transistor, an electrical signal corresponding to received light are two-dimensionally arranged; a lens section having a plurality of lenses arranged on the pixel array; and an image generating section for generating an image by using the electrical signal, wherein the image pickup section has the one pixel array including a plurality of image pickup regions onto which a subject image is formed by the lens section or a plurality of the pixel arrays including the one image pickup region, the image generating section generates the image by averaging the electrical signals for each of the pixels corresponding to one another among the image pickup regions, in order to reduce noise present in the electrical signal, and the image generating section includes: a calculation section for calculating a variance of the electrical signal provided from the pixel; a selection section for selecting, on the basis of the variance of each of the pixels, a combination of the image pickup regions so that a variance of the average value is minimized; and an integration section for integrating the images by averaging, on the basis of the combination of the image pickup regions, the electrical signal for each of the pixels corresponding to one another among the image pickup regions.
