IMAGE DATA FETCH METHOD, IMAGE DATA FETCH DEVICE AND IMAGE DATA FETCH PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image data fetch device not inviting the increase of processing time while preventing the increase of unrequired memory.;SOLUTION: An information code reader is constituted of a fetch data judging circuit 12 and an image data fetch circuit 13 as a main body. The fetch data judging circuit 12 judges the state of high-order 2 bits b9 and b8 outputted by 10 bits from an A/D converter for each pixel. The image data fetch circuit 13 stores the pixel data of 10 bits into an image memory as valid values for (a) 8 bits of bits b9 to b2, (b) 8 bits of the bits b8 to b1 and (c) 8 bits of the bits b7 to b0 for each fetch mode.;COPYRIGHT: (C)2003,JPO
