The present invention relates to a technique for correcting an image.
2. Description of the Related Art
In recent years, a technique for correcting the color balance, the luminance, and the like of a captured image in order to achieve optimum reproduction of the image by converting an analog image signal output from an image sensor or by converting an original image from an analog form to a digital form and correcting the original image in a circuit designed to cope with the analog signal and converting it to an analog signal has been developed.
In this case, with many image sensors including that disclosed in Japanese Patent Laid-Open No. 2002-80706 (hereinafter, referred to as Patent Document 1), a plurality of integration elements are arranged in a matrix in order to increase the number of pixels. However, the reading time for one pixel differs according to the area of the light-receiving region of each integration element. If an image is displayed on the basis of the image signal acquired as described above, for example, then the luminance is different between the background and the subject.
In addition, the signal level of each integration element differs depending on the area of the light-receiving region. Thus, if the correction that is optimal for the subject is made, for example, then, in the case of the background, an image of an overshoot and a decline occurs.
In order to cope with this problem, various techniques have been proposed. For example, Japanese Patent Laid-Open No. 2007-285805 (hereinafter, referred to as Patent Document 2) discloses an 0b46394aab
