Abstract
A solid-state imaging element includes: a pixel section having a plurality of pixels arranged in a matrix form, each of the pixels converting an optical signal into an electric signal and storing the electric signal according to exposure time; a dummy pixel section having dummy pixels arranged in a matrix form; and pixel drive sections adapted to control the pixel operations in such a manner as to operate an electronic shutter on and read the pixel section and dummy pixel section, wherein when an electronic rolling shutter is operated in which the pixels are shuttered row by row, the pixel drive sections judge whether the current and next frames are shuttered concurrently and in parallel so as to determine in which horizontal read period the dummy pixel section is to be shuttered.
