Abstract:
1. A solid-state image sensing device which can capture a moving image and a still image, comprising: a pixel array in which a plurality of pixel units are arranged to form a plurality of rows and a plurality of columns; a first readout circuit including a plurality of column circuits, each of which corresponds to a column of said pixel array and is constructed to read out a signal from said pixel array, wherein each of the plurality of column circuits reads out the signal from said pixel array in both a moving image capturing mode and a still image capturing mode; a signal holding unit constructed to hold the signals read out from said first readout circuit; a second readout circuit constructed to read out the signals held in said signal holding unit; and a current control unit constructed to control an electric current flowing through each of the plurality of column circuits while said first readout circuit reads out the signals, wherein said current control unit controls an electric current that is flowing through each of the plurality of column circuits during a period in which said first readout circuit reads out the signals in the moving image capturing mode to be smaller than an electric current that is flowing through each of the plurality of column circuits during a period where said first readout circuit reads out the signals in the still image capturing mode.
