Title: Ground removing device of image reproducing device
Inventor: OUCHI SATOSHI
IPC: H04N1/405
Filed: 1995-12-30
Abstract: PROBLEM TO BE SOLVED: To attain optimum ground removal without removing the highlight of a document unnecessarily as compared with a case wherein a uniform offset is applied by automatically deciding the kind of the document and varying a correction quantity after ground level detection according to the decision result. SOLUTION: From an image input device such as a scanner, RGB data (each consisting of 8 bits) which are linear to a reflection factor are outputted. Then a logarithmic conversion part 2 performs logarithmic conversion as preprocessing for making color corrections of a following stage to generate rgb data with linear density. Prior to main scanning, a document kind decision circuit 8 decides the document kind at prescanning time and a ground level detection part 9 detects the ground level of the document to decide the document kind. According to the decision result, a correction part 10 corrects the ground level.  Consequently, a copying machine which does not have a key for document kind switching automatically decide a document kind and performs density conversion corresponding to it, i.e., ground removal to eliminate the removal of the highlight of a pattern which is more than needed.
