Abstract: An image sensing device and an image sensing method are provided. The image sensing device includes a pixel array, first row-selecting lines, second row-selecting lines and a control circuit. Pixels in the pixel array are arranged to form a plurality of rows and a plurality of columns. A first set of the pixels of each row is electrically connected to the corresponding first row-selecting line, and a second set of the pixels of each row is electrically connected to the corresponding second row-selecting line. The control circuit performs an HFR readout process to obtain an image frame. The rows are divided into a selectable portion and an unselectable portion. In each of HFR readout periods, the first set of an unselected first row and the second set of an unselected second row are selected from the selectable portion of the rows.
