Abstract: A method of reducing memory requirement in the compensation memory unit of a scanner. The method includes providing an even compensation data value and an odd compensation data value and averaging the two to produce an odd-even compensation data value. Only half as much memory space is required to hold the averaged odd-even compensation data values.

Abstract: The present disclosure provides a repeated sampling method for image scanning. In one or more embodiments, the sampling method may comprise a sample treatment procedure for the data of an image scanning device during the scanning of an image. The method may comprise sampling, sorting, eliminating one or more group-departing values, and getting a mean value, etc. The sampling procedure may involve scanning a single point of the image several times to produce several sets of sampling values. The sorting procedure may involve sorting the several sets of sampling values after being sampled according to their magnitude. The eliminating group-departing values procedure may involve obtaining the relatively larger values and relatively smaller values from the several sets of sampling values after being sorted. The getting mean value procedure may involve obtaining a mean value from the several sets of sampling values. By applying the repeated sampling method the error of data pick-up during the procedure of scanning may be reduced.

Abstract: A scanning apparatus utilizing gravity acceleration for scanning is provided. The scanning apparatus comprises a U-shaped housing, a shaft bearing, a housing and a scanning head. The shaft bearing passes through the housing with two ends thereof respectively and rotationally fastened on two sidewalls of the U-shaped housing, thereby the housing is vertically and rotationally fastened in the U-shaped housing. The scanning head is disposed in the housing with an engageable piece engaged with a hook-shaped element of the housing so as to fasten the scanning head at a predetermined position close to the top end of the housing. When the scanning head is going to scan, the engagement between the engageable piece and the hook-shaped element is released and a starting power is applied to the scanning head by gravity acceleration. Thereby the scanning head is guided to move downward to scan via cooperation between a guiding piece and a guiding rail. The scanning speed of the scanning head is determined by the starting power controlled by a predetermined angle contained between the housing and the U-shaped housing.

Abstract: A method of reading data from a synchronous dynamic random access memory inside a scanner. The synchronous dynamic random access memory has a plurality of memory banks. A batch of random access data is stored inside any one of the memory banks and a batch of burst data capable of operating in the burst mode is stored in any other memory bank. The command for reading the random number data and the burst mode command for transmitting burst mode data are issued concurrently.
