<P>PROBLEM TO BE SOLVED: To shorten a time-lag until calculation of a flash emission amount and also reduce influence by an external light (another flash light and the like). <P>SOLUTION: A global resetting signal is applied with time difference separately to A group pixel comprising either pixel row of an odd row or an even row and to B group pixel comprising the other pixel row, among a plurality of pixels in a CMOS-type solid-state imaging device; a flash emission source is pre-emitted within the time difference; and when the pre-emission is performed, captured image data from A group pixel and captured image data from B group pixel are alternately read in order for light modulation of a flash emission amount in primary photography on the basis of difference between the both captured image data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
