Abstract: A system for adjusting a sensitivity of a camera module includes a memory unit configured for storing a plurality of pre-initialized pixel adjusting maps; an image capturing unit configured for capturing an image from the camera module and acquiring pixel values of the image to determine a pixel value range of the pixel values; a comparison unit configured for comparing the pixel range with the input-ranges of the pixel adjusting maps to determine which one of the input ranges of the pixel adjusting maps the pixel value range of the image; and an adjusting unit configured for adjusting the pixel value of the image to adjusting the sensitivity of the camera module according to the determined pixel adjusting map and outputting adjusted pixel values. The system can not only breakthrough the limit of the self-character of the amplifier, but also decrease noise in course of adjusting the sensitivity of the camera module.

Abstract: A safety LED lighting tube has a light cover, a base, a circuit board, and two electrical connectors. The light cover has a semi-circular hollow body made of a moldable material and has two side edges extending inwards and recessed to form rail channels. The base has a semi-circular body made of a moldable material and has a lower surface from which two hooked flanges project for slidable engagement with the rail channels formed on the side edges of the light cover. Ribs are formed on inward edges of the hooked flanges. The circuit board is received between and is supported by the ribs formed on the inward edges of the hooked flanges of the lower surface of the base. The circuit board has at least one LED. The electrical connectors are respectively mounted to opposite ends of the base and are electrically connected to the circuit board.

Abstract: A white balance adjustment method for a digital image capturing device is disclosed. The white balance adjustment method comprises the steps of: setting a color temperature estimation area; capturing an image with the digital image capturing device; choosing one or more analysis blocks from the image; determining whether values of Cb and Cr of each analysis block are located in either a color temperature zone or a white zone of the color temperature estimation area; collecting and calculating each point value of each color temperature that is located in the color temperature estimation area to obtaining a final color temperature; and performing a white balance adjustment procedure according to the final color temperature.
