Classification: H04N

Abstract:
An apparatus comprising:(A) an image sensing device; (B) an exposure state fixing device for fixing an exposure state so as to inhibit a change of the exposure state of said image sensing device; and (C) a signal processing device for performing a first image sensing operation for causing said image sensing device to perform an image sensing operation in an exposure state, and a second image sensing operation for causing said image sensing device to perform an image sensing operation in a non-exposure state, and processing a first image signal obtained by the first image sensing operation by a second image signal obtained by the second image sensing operation, said signal processing device having a first mode for causing said image sensing device to perform the first image sensing operation and then the second image sensing operation, and a second mode for causing said image sensing device to perform the second image sensing operation and then the first image sensing operation, and said image processing device operating in the second mode if said exposure state fixing device fixes the exposure state.
