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, to receive a light signal, and detect the brightness of the light signal. The control circuit also includes a calculating unit used to calculate the magnitude and the period of a flash of a strobe and an exposure parameter, a strobe control module used to control the strobe according to the calculated results of the calculating unit, and an exposure control module used to control an exposure module according to the exposure parameter.
