Abstract
A control method for an image capturing device is disclosed. The image capturing device includes a sensing circuit, an analog gain adjustment circuit using an analog gain, and an analog-to-digital converter (ADC). The control method includes: using a digital gain adjustment circuit to adjust, according to a digital gain, a digital image generated by the ADC to generate an adjusted digital image; generating the analog gain and the digital gain according to the digital image, and calculating intensity information of an infrared component in the digital image; and determining an image adjustment parameter according to the analog gain, the digital gain and the intensity information of the infrared component to perform image processing on the adjusted digital image.
