Claim:
1. A solid-state image pickup device, comprising: an image pickup section having a plurality of pixel arrays 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 a plurality of the pixel arrays each including one image pickup region onto which a subject image is formed by the lens section, 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, for each of the pixels corresponding to one another among the image pickup regions, a variance of the electrical signal provided from the pixel; a selection section for selecting, on the basis of the variances output from the calculation section, a combination of the image pickup regions so that a variance of the average value of the pixels, each pixel corresponding to one another among the image pickup regions, 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.
