Abstract
A mechanism, of a camera, to let a light adjustment operation for a flash light be performed with a higher precision in a shorter time. The mechanism includes: a first device for taking an image of a region to be photographed and for outputting image process information; a second device for detecting a main subject region and for detecting a background region on the basis of the image process information, in which the second device outputs main subject information upon the main subject region thus detected and outputs background information upon the background region thus detected; a third device for calculating a compensation value for light adjustment on the basis of the main subject information and on the basis of the background information; and a fourth device for controlling an amount of flash light emission at time of taking a photograph with an emission of the flash light on the basis of the compensation value for light adjustment.
