Abstract
An integrated image fetching device integrates a control circuit and a CMOS sensor on a substrate. The control circuit includes a photometry module used to control a detecting flash, receive light signal and detect lightness the light signal; a calculating unit used to calculate the magnitude and the period of a flash of a strobe and an exposure parameter; a strobe controlling module used to control the strobe according to the calculated results of the calculating unit; an exposure controlling module used to control an exposure module according to the exposure parameter.
