Patent ID: 7839435

Claim:
An image sensing apparatus having a first mode and a second mode, comprising: an image sensing unit configured to photo-electrically convert an object image to an image signal; a first image generation unit configured to generate a first image obtained from said image sensing unit; a second image generation unit configured to generate a second image corresponding to a predetermined region of the first image; an AE data acquisition unit configured to acquire each of AE data of the first image and the second image; a calculation unit configured to calculate an exposure correction amount and to calculate a brightness correction value; a brightness correction unit configured to correct brightness by using the calculated brightness correction value; and a display control unit mounted in the image sensing apparatus to display the first image and the second image that are made to have appropriate brightness by said control unit as one frame image, wherein, when the first mode is selected, said calculation unit calculates the exposure correction amount based on the AE data of the second image and calculates the brightness correction value based on the calculated exposure correction amount and the AE data of the first image, and said brightness correction unit corrects brightness of the first image based on the calculated brightness correction value, and wherein, when the second mode is selected, said calculation unit calculates the exposure correction amount based on the AE data of the first image and calculates the brightness correction value based on the calculated exposure correction amount and the AE data of the second image, and said brightness correction unit corrects brightness of the second image based on the calculated brightness correction value.
