Abstract:
An image sensing apparatus comprises: a pixel array; a plurality of column signal lines; a readout unit; a driving unit that, in a transferring period for the readout unit to transfer pixel signals of columns in a first row to the output line, supplies to the pixel array and/or the readout unit a driving pulse for reading out the pixel signals from a second row, in a transferring period for the readout unit to transfer the pixel signals of the columns in the first row to the output line; and a correction unit that corrects a pixel signal of a first column in the first row that was transferred by the readout unit at a timing at which a level of the driving pulse transitions in the transferring period, according to at least a level of a pixel signal of the first column in the second row.
