<P>PROBLEM TO BE SOLVED: To make a focus and exposure accurately follow a movement and a brightness change of a subject, even in rapid continuous shooting. <P>SOLUTION: Mirror-down is executed after picking up an image in the first frame, and a face is recognized in an obtained image data. An face area is predetermined, and a brightness of the area is obtained from the image data. A division photometric area corresponding to the face area is extracted based on coordinate data of the face area, and a brightness of the area is obtained from the image data. Then, an accumulation time of a photometric sensor is found based on the image brightness of the extracted division photometric area, for photometry in the second frame executed after the mirror-down. Exposure calculation is carried out based on an obtained photometric brightness after the photometry in the second frame, and exposure values (diaphragm value, exposure time) are determined to pick up an image in the second frame. The same manner is repeated hereafter. <P>COPYRIGHT: (C)2010,JPO&INPIT |
