Abstract
A simulator simulates a hard copy to be made and displays an image thereof on a color monitor. In such a simulation, a lighting condition correction unit corrects a video signal in accordance with the lighting conditions where the color monitor is installed. The color balance and density of the simulated image under an illumination thus are the same as the hard copy to be made.
Claims13
A hard copy simulator comprising:
- means for simulating a hard copy to be made;
- a color monitor for displaying a simulated image simulating said hard copy;
- and
- correction means for correcting said simulated image, said correction means comprising:
- first means for storing a first look-up table containing data on lighting conditions where said color monitor is installed;
- second means for storing a second look-up table containing data on density and color balance for said simulated image;
- and
- means for correcting said simulated image in accordance with said lighting conditions where said color monitor is installed based on a content of said first means independently of said second means.

A video printer comprising:
- a memory for storing an inputted color video signal;
- image processing means for processing said color video signal read out from said memory;
- a monochrome CRT driven by said color video signal outputted from said image processing means for displaying a red image, green image, and blue image in black-and-white, and projecting a black-and-white image for printing onto a color photographic paper;
- three primary color filters, disposed between said monochrome CRT and said color photographic paper, for converting said black-and-white image projected from said monochrome CRT into a monochromatic image;
- means for processing said color video signal read out from said memory and simulating a color image to be printed on said color photographic paper to provide a simulated image;
- a color monitor for displaying said simulated image;
- and
- correction means for correcting said simulated image, said correction means comprising:
- first means for storing a first look-up table containing data on lighting conditions where said color monitor is installed;
- second means for storing a second look-up table containing data on density and color balance for said simulated image;
- and
- means for correcting said simulated image in accordance with the lighting conditions where said color monitor is installed based on a content of said first means independently of said second means.

A photographic printer comprising:
- a photographic printing system for printing an image of a photographic film on a color photographic paper;
- a color TV camera for picking up the image of said photographic film and outputting a color video signal;
- means for processing said color video signal to simulate a color image to be recorded on said color photographic paper and provide a simulated image;
- a color monitor for displaying said simulated image;
- and
- correction means for correcting said simulated image, said correction means comprising:
- first means for storing a first look-up table containing data on lighting conditions where said color monitor is installed;
- second means for storing a second look-up table containing data on density and color balance for said simulated image;
- and
- means for correcting said simulated image in accordance with the lighting conditions where said color monitor is installed based on a content of said first means independently of said second means.
