Imaging apparatus and method for controlling flash emission

摘要

An imaging apparatus includes: flash driving means for driving a flash during a set preliminary emission period and a set main emission period; and an image sensor constituted by a plurality of photoelectric converting elements which are arranged in a matrix and capable of being accessed randomly. The charge accumulation initiation timing and the charge accumulation cessation timing of the photoelectric converting elements line are controlled line by line or pixel by pixel. The imaging apparatus forms images employing pixel signals output from the photoelectric converting elements, and determines main regions within the images. The preliminary emission period is set such that charge accumulation in photoelectric converting elements corresponding to pixels that constitute the main region is initiated prior to the preliminary emission period and ceased after the preliminary emission period. The flash driving means drives the flash during the set preliminary emission period.
