Problems solved by technology

Taking the CCD of Sony ILX558K as an example, the number of input and output pins (pins) is as high as 12, which will increase the cost due to the large number of signal lines.
Moreover, since the optical analog signal RGB transmitted back from the CCD module 115 to the motherboard 150 is extremely susceptible to electromagnetic interference (Electromagnetic Interference, EMI), the optical analog signal RGB is likely to be distorted due to electromagnetic interference.
This will degrade the quality of the resulting image

Abstract

An optical scanning module is configured in a scanning device for picking up images of files including: an optical sensing component, a front processor and a special used IC, in which, the optical sensing component senses the optical signals of related files and converts the optical signals to analog image signals, a front processor is coupled with an optical sensing component and receives analog image signals and transforms them to digital image signals, the special application IC is used in receiving and processing digntal image signals and outputs them.

Description

technical field [0001] The invention relates to a scanning device, in particular to a scanning device which integrates a light sensing component, a front-end processor and a special application integrated circuit on an optical scanning module. Background technique [0002] refer to figure 1 , which illustrates a conventional scanner block diagram. The scanner includes two major image processing components, an optical scanning module 110 and a main board (Main Board) 150 fixed on the scanner body. The optical scanning module 110 is equipped with a Charge-Coupled Device (CCD) module 115 for receiving optical signal, while the application specific integrated circuit (Application Specific Integrated Circuit, ASIC) 151 and the analog front end (Analog Front End, AFE) processing device 153 on the motherboard 150 are used to control the charge-coupled device module 115, and the sensed The optical signal is extracted and converted to form an image signal tha...
