Abstract

There is described a method and apparatus for producing prints, such as post cards, etc. The print producing apparatus includes a processor to generate a second character information by applying a first processing to a first character information and to generate a second image information by applying a second processing, being different from the first processing, to a first image information, after extracting the first character information and the first image information separately from a first image data which includes the first character information and the first image information, so as to generate a second image data which includes the second character information and the second image information, and a printer to produce prints by forming images, based on the second image data generated by the processor.

Dependent claims

A method for producing a print by exposing an image onto a photosensitive material, comprising the steps of:

extracting character image data and pictorial image data separately from original image data, which originally include said character image data and said pictorial image data;
applying a first image-processing operation to said character image data by employing a first LUT for converting image values of pixels, represented by said character image data, to first exposure control values, so as to generate revised character-image data, which represent said first exposure control values;
applying a second image-processing operation to said pictorial image data by employing a second LUT for converting image values of pixels, represented by said pictorial image data, to second exposure control values, so as to generate revised pictorial-image data, which represent said second exposure control values;
combining said revised character-image data with said revised pictorial-image data, so as to generate processed image data, which include both said revised character-image data and said revised pictorial-image data;
and
forming an output image on said photosensitive material, based on said processed image data, so as to produce said print.

An apparatus for producing a print by exposing an image onto a photosensitive material comprising:

an extracting section to extract character image data and pictorial image data separately from original image data, which originally include said character image data and said pictorial image data;
a first image-processing section to apply a first image-processing operation to said character image data by employing a first LUT for converting image values of pixels, represented by said character image data, to first exposure control values, so as to generate revised character-image data, which represent said first exposure control values;
a second image-processing section to apply a second image-processing operation to said pictorial image data by employing a second LUT for converting image values of pixels, represented by said pictorial image data, to second exposure control values, so as to generate revised pictorial-image data, which represent said second exposure control values;
a data combining section to combine said revised character-image data with said revised pictorial-image data, so as to generate processed image data, which include both said revised character-image data and said revised pictorial-image data;
and
an image forming section to form an output image on said photosensitive material, based on said processed image data, so as to produce said print.
