Abstract
A color image processing apparatus comprises: a device to supply color image data obtained by photoelectrically converting an object image; a changing circuit which has a density conversion table and changes the density of the color image data supplied by the supplying device into a plurality of densities on the basis of the table; and a reproducing device such as a bubble jet printer for reproducing the image data whose density was changed by the changing circuit as a plurality of visible images which can be simultaneously seen. With the apparatus, an image of a desired color or density can be preferably reproduced.
Claims43
An image processing apparatus comprising:
- a) means for supplying image data in first and second regions;
- b) changing means for changing a density of the image data supplied by said supplying means into a plurality of densities different from each other, wherein the plurality of densities correspond to the same image data;
- and
- c) reproducing means for reproducing the image data as a plurality of visible images which can be simultaneously seen, each of the visible images having a corresponding one of the plurality of densities;
- wherein a change of density of the image data in the first region by said changing means is the same as a change of density of the image data in the second region by said changing means.
An image processing apparatus comprising:
- a) means for supplying color image data;
- b) changing means for changing a color tone of the color image data supplied by said supplying means into a plurality of levels different from each other, wherein the plurality of levels correspond to the same color image data;
- and
- c) reproducing means for reproducing the color image data of which color tone is changed by said changing means as a plurality of visible images which can be simultaneously seen, each of the images having a corresponding one of the plurality of levels,
- wherein said reproducing means includes delaying means for delaying the color image data for forming a plurality of color component images.
An image processing apparatus comprising:
- a) designating means for designating on a color original;
- b) image reading means for scanning a part of the color original including an image in the image reading region designated by said designating means;
- c) density changing means for changing a density of a predetermined color of the image which was scanned by said reading means into a plurality of predetermined densities different from each other;
- and
- d) reproducing means for reproducing the image having the changed density as a visible image at a predetermined position each time the density of the predetermined color is changed.
An image processing apparatus comprising:
- a) means for supplying image data;
- b) changing means for changing a density of the image data supplied by said supplying means into a plurality of densities different from each other, wherein said plurality of densities correspond to the same image data;
- c) binarizing means for binarizing the image data of which density is changed by said changing means;
- and
- d) reproducing means for reproducing the image data binarized by said binarizing means by depositing an ink on a recording medium, as a plurality of visible images which can be simultaneously seen, each of the visible images having a corresponding one of the plurality of densities.
An image processing method comprising the steps of:
- a) supplying color image data;
- b) changing a predetermined amount of a predetermined color component constituting the color image data;
- and
- c) repeating said supplying step and said changing step, wherein during said repeating step, the predetermined amount is changed successively per each repetition.
An image processing apparatus comprising:
- a) means for supplying image data;
- b) changing means for changing a density of the image data supplied by said supplying means into a plurality of densities different from each other, wherein the plurality of densities correspond to the same image data;
- c) binarizing means for binarizing the image data of which density is changed by said changing means;
- and
- d) reproducing means for reproducing the binarized image data as a plurality of visible images which can be simultaneously seen, each of the images having a corresponding one of the plurality of densities.
