Abstract
Provided is an image sensor including a sensor array including a plurality of pixels arranged in rows and columns. The image sensor may include a ramp signal generator which may generate a ramp signal. The intensity of the ramp signal may increase or decrease in response to a ramp enable signal. The image sensor may include an analog-digital converter electrically connected to one of the columns of the pixels. The analog-digital converter may be configured to compare an output signal from the one of the columns of the pixels with the ramp signal, thereby generating time information. The analog-digital converter may be configured to convert the time information to digital information in response to a counter enable signal. An activation of the counter enable signal may be delayed by a predetermined time delay, compared with that of the ramp enable signal.
