Abstract
An image sensing apparatus capable of reducing degradation of a signal-to-noise ratio property occurring when a driving frequency of an image sensing element is high, depending on a state of an operation mode. An information table is stored in a memory section, which includes information on a timing of a horizontal transfer driving signal for performing charge transfer in the horizontal direction in an image sensing element, information on a timing of a reset gate signal for performing charge sweep per pixel, and information on a timing of a feed-through sample-hold signal for sample-holding a feed-through section of the output signal of the image sensing element which becomes a black reference per pixel, in association with an operation mode of an image sensing apparatus. The information table associated with the set operation mode is selected from the memory section, and the element is driven based on the information table.
