Abstract: An image acquiring device with background filtering function includes a scanning module, a color splitting module and an image processing module. The scanning module includes a CCD sensor for sensing a document image signal travelling along an optical path. The CCD sensor has red, green, blue and white light sensing member sets. A data transmission speed of the white light sensing member set is greater than that of each of the red, green and blue light sensing member sets. The color splitting module disposed on the optical path only lets one of red, green and blue light pass through at a time under a filtering mode. The white light sensing member set receives the red, green or blue light outputted from the color splitting module. Then, the image processing module recognizes a brightness value of a pixel, which exceeds a predetermined value, and compensates for the brightness value of this pixel to generate a brightness value corresponding to a white.

Abstract: A light source module includes a base, a cold cathode fluorescent lamp (CCFL) and an auxiliary light emitting unit. The CCFL disposed on the base provides main light. The auxiliary light emitting unit disposed on the base includes a plurality of light emitting diodes (LEDs) respectively disposed adjacent to two ends of the CCFL. The auxiliary light emitting unit provides auxiliary light to compensate for the main light, wherein the light source module emits scanning light, which is substantially uniformly distributed along a length of the CCFL.
