Abstract: In some embodiments, an image sensing device includes a pixel array including a capacitor, a read circuit, and a plurality of pixels including a first and a second photodiode. The image sensing device further includes a driver configured to generate control signals for the plurality of pixels, an analog-to-digital converter (ADC) block configured to generate a digital signal, and a controller configured to control the driver and the ADC block. At least one of the plurality of pixels is configured to sequentially output a first and a second sub-output signal obtained by converting charges accumulated in the first photodiode, a third sub-output signal obtained by converting charges accumulated in the second photodiode, a fourth sub-output signal obtained by converting third charges stored in the capacitor, a first reset signal corresponding to the fourth sub-output signal, and a second reset signal corresponding to the third sub-output signal.

Abstract: A time of flight (ToF) sensor includes: a first pixel including a first photogate to receive light reflected by an object and generate a first phase signal, and a second photogate to generate a second phase signal having a phase difference of 180 degrees with respect to the first phase signal; a second pixel including a third photogate to receive the reflected light and generate a third phase signal different from the first phase signal and a fourth photogate to generate a fourth phase signal having a phase difference of 180 degrees with respect to the third phase signal; a first signal output unit to output the first and second phase signals; and a second signal output unit to output the third and fourth phase signals, wherein the first, second, third and fourth photogates output the first to fourth phase signals during a frame period.
