PROBLEM TO BE SOLVED: To perform removing processes (NR process) for random noise properly when a moving picture is picked up by a camcoder and when a still picture of a negative film is picked up with a film adapter mounted respectively. SOLUTION: In still picture mode, the coefficient (k) of a coefficient multiplier 508 is set to, for example, 1 with the signal of a terminal 502. The still picture Y signal from a terminal 501 and the image signal after an NR(noise reduction) process in a last frame from a memory 8 are processed by a subtracter 505 and an absolute value circuit 506 and multiplied by the coefficient (k), a sign bit is added, and a subtracter 511 subtracts the result from the source still picture Y signal. The subtraction output is outputted as an image signal after the NR process from a terminal 512 and stored in the memory 8 through a terminal 504. In moving picture mode, on the other hand, the coefficient (k) is set smaller than that in the still picture mode.
