Abstract
There is provided a control method of a microfilm image reader, in which a scanner reads an image in a frame recorded on a microfilm and supplies image data of the read image to a printer, for printing out image data of an original image faithfully in a relatively easy processing even if the original image largely contains middle tone portions, without either calculating a threshold value for binarization by a complicated method or performing a special image processing to be uniquely performed to a binary density image. The scanner reads the image in a multi-tone gradation and the printer prints out image data of at least one portion of the read image in the multi-tone gradation. When the image in a frame contains both a multi-tone gradation portion in a photograph area and a binary density portion in a document area, image data of the photograph area and image data of the document area are printed out in the multi-tone gradation and the binary density or gradation, respectively. If the frames are photographed on the microfilm in a predetermined form or forms, coordinates of the photograph area are previously memorized in each form so that the photograph area can be printed out in the multi-tone gradation automatically.
