A picture signal processing circuit includes: a filter unit, when, based on first picture signals supplied from an image sensing device that images a subject in a first picture size determined by a first number of pixels, a first or second display mode for display of a picture on a display unit having a picture size determined by a second number of pixels smaller than the first number of pixels is set, that outputs second picture signals obtained by performing filter processing of removing high-frequency components from the first picture signals in the first display mode and outputs the first picture signals without change in the second display mode; a memory control unit that allows a memory to store the first or second picture signals supplied from the filter unit, and reads out the second picture signals from the memory, performs processing of reducing from the first picture size to the second picture size on the second picture signals, and output the signals to the display unit in the first display mode, and reads out the first picture signals corresponding to a picture clipped in the second picture size from the picture in the first picture size from the memory and outputs the signals to the display unit in the second display mode; and a main control unit that controls switching between the first and second picture signals filter-processed or read out from the memory by the memory control unit according to a command of switching between the first and second display modes provided by a display mode switching unit that provides the command of switching between the first and second display modes.
