PROBLEM TO BE SOLVED: To normally open a mechanical shutter after a fixed time elapses from a shutter release by a shutter release button. SOLUTION: A compression CPU 23 clocks a data setting timeαwhen the shutter is released. The communication of gain data, etc., for adjusting white balance is performed between the compression CPU 23 and a CPU 31 during the data setting timeα(code 107) and the gain data are set in a signal processing circuit, etc. After the data setting timeαelapses, generation is started concerning a vertical synchronization reference signal (VD signal) by 1/60-second-cycle (time t5). A focal plane shutter is released after the passage of an exposure preparation timeβ(=4VD) from the generation of the VD signal and a CCD 11 is exposed. After the exposure an electric charge is read from the CCD 11 and the signal is processed (code 111). |
