Abstract
An image sensing device includes: a pixel configured to output a reference signal corresponding to a sensing node that is reset and an image signal corresponding to the sensing node in which photocharges are accumulated, in each of a high conversion gain (HCG) mode and a low conversion gain (LCG) mode; an analog-to-digital converter (ADC) configured to sequentially perform analog-to-digital conversion of the reference signal of the HCG mode, the image signal of the HCG mode, the image signal of the LCG mode, and the reference signal of the LCG mode; and a ramp generator configured to generate a first ramp signal that is used for analog-to-digital conversion in the HCG mode, and to generate a second ramp signal that is used for analog-to-digital conversion in the LCG mode while having a waveform different from that of the first ramp signal.
