Abstract:
A CPU 200 reads out an image file GF from a memory card MC and stores the read out image file GF temporarily in an RAM 210. The CPU 200 acquires shooting information EI from the read out image file GF and determines the noise reduction level according to the ISO speed. When the ISO speed or the shutter speed exceeds a predetermined value, the CPU 200 increases the noise reduction level and executes noise reduction process.
