Abstract:
A method for driving an image sensor includes the steps of: sensing temperature from the image sensor; selecting a voltage level of a control signal in accordance with the sensed temperature; and detecting an image in response to the control signal having the selected voltage level. An image sensor comprises a temperature sensor configured to sense a temperature of the image sensor and a pixel array configured to detect an image in response to a control signal, wherein the control signal varies in voltage level as a function of the sensed temperature.
