description An image sensor having improved signal-to-noise ratio and reduced random noise and an image processing system are provided. The image sensor includes a pixel array including a pixel connected to a column line and configured to provide an analog pixel signal to the column line in response to at least one row control signal, and an analog-to-digital converter (ADC) that receives and converts the analog pixel signal into a corresponding digital pixel signal. The pixel includes a group of sub-pixels simultaneously selected by the at least one row control signal, such that each one of the sub-pixels in the group of sub-pixels provides a sub-pixel signal, and the analog pixel signal is an average of the sub-pixel signals provided by the group of sub-pixels.
