Abstract:
A method of an image sensor device includes: using a pixel array of the image sensor device to sense and generate at least one dark image; computing pixel statistics according to the at least one dark image; and, determining which one of a plurality of temperature ranges a temperature of the image sensor device falls within according to the pixel statistics.
