Abstract
A camera system includes a lens unit, an image sensor, a sensing unit, an adjustment unit, a memory, and a controller. The lens unit focuses reflected light to form an image. The image sensor converts the image formed by the lens unit into a digital image. The sensing unit senses an internal temperature of the camera system and an external temperature outside the camera system. The adjustment unit adjusts the lens unit. The memory stores preset adjustment amounts for adjusting the lens unit according to different internal temperatures of the camera system operating at different external temperatures. The controller receives the internal temperature and the external temperature sensed by the sensing unit, retrieves the corresponding preset adjustment amount from the memory according to the sensed temperatures, and controls the adjustment unit to adjust the lens unit according to the preset adjustment amount.
