Abstract

PURPOSE:To record a still picture without using a recording medium such as a magnetic disk by devising a memory to be attached and detached to/from a camera main body freely and storing the still picture subject to digital signal processing in the camera main body to an assembly of the storage element constituting the memory. CONSTITUTION:A picture memory 14 is provided, which is loaded attachably and detachably to a tape cassette cover of a camera main body 13 and stores the still picture subject to digital signal processing in the camera main body 13 into an assembly of the storage element. The picture memory 14 is n-set of RAMs able to write and read signals in pair with for storing luminance and chrominance signals 25a, 25b. A write memory selection switch 26 is closed and a shutter button 28 is depressed, then a picture data is supplied to the luminance signal and chrominance signal RAMs 25a, 25b connected to the write memory selection switch 26 to write the still picture data separated from the luminance and chrominance signal.
