Abstract
A picture signal processing circuit includes a filter unit, a memory and a main control unit. When a display operates in a first display mode, the filter unit removes high-frequency components from first picture signals supplied in a first picture size from an imaging device, to provide second picture signals. When the display operates in a second display mode, the picture signals are provided unchanged. The memory stores the first and second picture signals, reads out the second picture signals, changes the second picture signals from a first picture size to a second picture size and supplies those second picture signals to the display when the display operates in the first display mode. The first picture signals corresponding to a picture clipped from the first picture size to the second picture size are read out to the display when the display operates in the second display mode. The main control unit controls switching between the first picture signals and the second picture signals from the memory according to whether the first or second display mode is selected.
