SUB-SAMPLING WITH HIGHER DISPLAY QUALITY IN IMAGE-SENSING DEVICE

An image-sensing device includes a driver and an array of pixels. The driver controls the array of pixels to output a combined image signal that is a combination of at least two image signals for at least two aligned pixels in at least two rows, for reducing vertical resolution in the sub-sampling mode. In addition, a mixing circuit further averages the resulting combined signals for M consecutive odd or even columns for reducing horizontal resolution in the sub-sampling mode.
