Title: Image processor
Inventor: ARAI HIROSHI
IPC: H04N1/60
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide the image processor where a background is eliminated under an optimum condition corresponding to a set-off of an original image to form an image with high quality. SOLUTION: A mean MTF is obtained from received image data (RGB data in the case of color data). A plurality of lines of received image data (number of lines in response to a filter size) are stored in a memory, and an MTF detection circuit 601 provides an output of MTF in the unit of one pixel. As an example of the filter size, a 3×3 Laplacian filter is depicted. The MTF detection circuit 601 uses the Laplacian filter except the filter size and the coefficient. The MTF output is stored by pluralities of lines (number of lines in response to a discrimination area) is stored in the memory and a mean value is outputted from an averaging circuit 602 in the unit of one pixel. A discrimination circuit discriminates whether or not the mean value output is set-off data.  When the MTF mean value is a specified value or below, it is discriminated to be a set-off original and background elimination ON is outputted.

A comparator 14 compares the output with the output from the region 10 to raise the bias voltage of the region 10 through the controller 10 when the latter is smaller, and to lower it if it is larger.
