Abstract
An image sensor and an operating method of the image sensor may include a pixel array including a plurality of pixels; a controller configured to generate a pre-shutter driving signal associated with a pre-shutter operation, the pre-shutter driving signal generated before a first shutter operation and a first read operation corresponding to photographing a first frame is performed; a row driver configured to drive first control signals to the pixel array based on the pre-shutter driving signal, the first control signals associated with the pre-shutter operation; and the pixel array is configured to perform the pre-shutter operation in response to the first control signals, wherein levels of the first control signals correspond to levels of second control signals, the second control signals associated with the first read operation.
