ABSTRACT:
An image sensing apparatus has an image sensing element for photoelectric conversion, a shutter for selectively creating a light-shielded state and non-light-shielded state for the image sensing element, a bright signal storage unit for storing a bright signal output from the image sensing element in the non-light-shielded state, a dark signal storage unit for storing a dark signal output from the image sensing element in the light-shielded state, an operation unit for subtracting the dark signal from the bright signal to obtain a signal with suppressed dark noise, and a control unit for controlling read of bright and dark signals from the image sensing element in accordance with the relationship between the exposure time of the image sensing element and the photographing time interval.
