Title: Color image reader
Inventor: FUKUNAGA KOJI
IPC: H04N1/04
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To read color images at a high speed by judging the presence/absence of valid data within image data, skipping successively performed image read scannings in respective colors and informing a host of a fact that they have been skipped. SOLUTION: In the execution of scanning, signals obtained from a photodetector 12 are converted into an image data by an image data A/D conversion computing part 13 and a digital image data transfer part 15. The data density of the image data obtained by the scanning is calculated, and in the case that no Red data are present on a scanner side, the scanning and data transfer in Green and Blue are not performed, and the host is informed of the fact that no Red image data is present. In the host, in the case of being informed of the absence of the Red data from a scanner, the data reception of the other colors is skipped. Thus, the time of scanning a part without the data in an original may be reduced and the total read speed can be accelerated.
