Abstract
A solid-state imaging device which can generate finite difference data of images at different times. There are provided with photoelectrical converting sections each of which includes photodiodes disposed in a matrix array and receives incident light to generate signal charges. A signal charge difference generating section generates a signal charge difference at different times from the signal charges generated in the photoelectrical converting section. A signal charge difference transfer section transfers the signal charge difference generated as an output of the device.
