    摘要: Image data for a margin around the image area of a book form original can be erased and image data for a book center portion are obtained without loss. In a photograph mode, a low threshold value is set in first binary conversion means 4, and image data having been input are binary converted by using this value. Based on the image data having been converted, a first coercion signal generating unit 6 judges a margin around the original image. A high threshold value is set to second binary conversion means 5 and image data having been input are binary converted by using this value. Based on the image data having been converted, a second coercion signal generating unit 7 judges a margin around the original and a portion including a book center portion. A character processing binary conversion unit 3 carries out binary conversion on input image data for the portion within the original, and outputs whitening data which erase the margin around the original. A photograph processing binary conversion unit 2 carries out tone image binary conversion only on the book center portion in the input image data and outputs the data thereof. An image processing selecting unit 10 makes the image data for the portion within the original image selectively output from the character processing binary conversion unit 3 and makes the image data for the book center portion selectively output from the photograph processing binary conversion unit 2.

    摘要: An image forming system includes a thermal head having a linear array of a plurality of heater elements extending in a direction of the main scanning, and a head driver which drives the thermal head on the basis of image data to selectively operate the respective heater elements according to image data while the thermal head is being moved relative to a recording medium in a direction of the sub-scanning, thereby forming a copy of the image represented by the image data on the recording medium line by line. The heater elements are divided into a plurality of head blocks which are contiguous in the main scanning direction, and the head driver is provided with a plurality of head drive segments of the same number as the number of the head blocks. Image data consisting of a plurality of pieces of line image data is stored in a memory. Each line image data consists of a plurality of image data fractions which are of the same number as the number of the head drive segments. When contiguous multi-imaging is to be carried out, the image data fraction of each of the pieces of line image data corresponding to the part to be multiplied of the image is input into the head drive segments which drive the head blocks corresponding to the positions where the copies are to be formed.

    摘要: A heat-sensitive stencil master making system includes a thermal head having an array of a number of heater elements which extends in a main scanning direction substantially perpendicular to a sub-scanning direction in which the thermal head is moved relatively to heat-sensitive stencil master material when imagewise perforating the heat-sensitive stencil master material. Each of the heater elements is longer in the main scanning direction than in the sub-scanning direction.

    摘要: An operator can select image processing for a half tone image area among a plurality of processing methods, and image processing appropriate for the image can be carried out thereby. An original image is read by an image sensor 1 and output through either simple binary conversion by binary conversion means 3 for character processing or half tone image processing by binary conversion means 2 for photograph processing. Judging means 6 judges whether image data are of a character image area or a half tone image area, and switches output between the binary conversion means 3 for character processing and the binary conversion means 2 for photograph processing. The binary conversion means 2 for photograph processing includes error diffusion processing means 10 and dither processing means 11. By setting of setting means 13 carried out by an operator, output from either the error diffusion processing means 10 or the dither processing means 11 is selected for a half tone image.
