Patent ID: 8558908

Claim:
An image sensing apparatus comprising: an image sensing unit that converts light into an electric signal corresponding to a quantity of incident light, and periodically outputs an image signal obtained by the conversion at intervals of a predetermined period; a mode switch that switches among a plurality of image sensing modes including at least a special image sensing mode and a normal image sensing mode; a delay unit that delays an image signal by the predetermined period; an attenuator that attenuates the image signal output from the image sensing unit and the image signal output from the delay unit according to set attenuation proportions; an adder that adds the attenuated image signals and outputs an image signal obtained by the addition; and a setting unit that sets the attenuation proportions used by the attenuator, according to the image sensing mode selected by the mode switch, wherein the delay unit delays the image signal obtained by addition performed by the adder, and wherein the setting unit sets the attenuation proportion of the image signal output from the delay unit higher in the special image sensing mode than in the normal image sensing mode.
