Abstract
An image capturing device includes an electronic image sensor and a memory including a dark frame buffer that stores one or more dark frames generated by the electronic image sensor. A processor controls the electronic image sensor to substantially continuously capture and store a newest dark frame from the electronic image sensor when the electronic image sensor is not performing an image capture. The processor subtracts the newest dark frame from an image upon an image capture.
