Abstract
An image sensing apparatus and method utilizing an image sensor, an auto white balance adjustment section, a change point detection section, and an electronic mark data generation section. The image sensor senses an image of an object and outputs an image signal corresponding to the image of the object. The auto white balance adjustment section automatically adjusts white balance of the image signal corresponding to a change of the image signal. The change point detection section detects a change point of the white balance corresponding to at least an adjustment value of the white balance while the image sensor is sensing the image of the object. The electronic mark data generation section generates electronic mark data for adjusted white balance based on time information of the change point detected by the change point detection section.
