An output from a solid state image sensing device spatially modulated by a color filter is A/D converted and stored in a field memory. Digital signals read from the field memory during electronic zooming are successively delayed by 1H period by means of first, second and third 1H delay elements connected in series. The output from the field memory and outputs from the first, second and third 1H delay elements are separated into luminance components and line sequential color components by first to fourth Y/C separating circuits, respectively. A first set of three primary color signals are calculated based on outputs from the first, second and third Y/C separating circuits, and a second set of three primary color signals are calculated based on outputs from the second, third and fourth Y/C separating circuits. Three primary color signals corresponding to a new display point formed along with the execution of electronic zooming function are formed based on the calculated two sets of three primary color signals, and a luminance signal corresponding to the new display point is formed based on outputs from the first and second delay elements.
