Abstract:
1. An image sensing apparatus comprising: an image pickup device configured to output an image signal of an object; an infrared ray cut filter configured to cut an infrared ray, which is inserted into an optical path associated with the image pickup device and removed from the optical path; a detection device configured to detect luminance of the object, wherein the detection device is arranged in a different place from the image pickup device; and a control device configured to control to insert and remove the infrared ray cut filter in accordance with at least one output of the image signal from the image pickup device and the luminance detected by the detection device, wherein a luminance detection area of the detection device is a narrower area within an image pickup area of the image sensing device, and wherein the control device controls to insert and remove the infrared ray cut filter in accordance with a difference between luminance information of the detection device and luminance information of an area of the image pickup device corresponding to the luminance detection area of the detection device and a predetermined threshold level for switching.
