Abstract
Abstract A monitor adjusting system facilitates image adjusting procedures such as color or density correction. Prior to printing an image onto photosensitive paper, the exposure settings are selected so that the printed image on the print paper will have proper colors and densities. Initial adjustments are made to the exposure setting based on the actual images being developed. To check the correctness of the changes in exposure setting for the actual images, the operator inserts a color calibration (reference) film strip which is read and displayed by the system. The film strip will display two images: (1) a reference scene of a human subject or a landscape and (2) either a density chart or a color chart. The images are used as indicators of the correctness of the adjustments made. Using the color chart separates out the effects of exposure on individual colors, while the landscape or human image simultaneously displays the effected exposure settings on a great number of color components in a complicated mixed pattern. This provides two sets and types of indicators to facilitate the correction of exposure to the point that even inexperienced operators can make corrections with relative ease.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
A monitor adjusting system for an image printer operable to obtain an exposure condition based on image information picked up by an image sensor from a film and having monitor for displaying a simulated image of a finished photographic print produced by using the exposure condition, the system comprising: a color calibration film including a color chart image having a plurality of separate areas having different colors from each other and a reference image comprised of a natural image of a photographic subject such as a human subject and a landscape subject; image information correcting means for producing a simulated image of said color chart image and said reference image from image information read from said color calibration film; display control means for transmitting said simulated image to said monitor; and a control panel for controlling said image information correcting means while viewing said simulated image of said color image and said reference image being displayed simultaneously on said monitor so as to obtain appropriate quality in said simulated image of said color chart image and said reference image displayed on said monitor.
Claim 2
Dependent Claim
183 words
A monitor adjusting system for an image printer operable to obtain an exposure condition based on image information picked up by an image sensor from a film and having monitor for displaying a simulated image of a finished photographic print produced by using the exposure condition, the system comprising: a color calibration film including a color chart image having a plurality of separate areas having different colors from each other and a reference image comprised of a natural image of a photographic subject such as a human subject and a landscape subject; image information correcting means for producing a simulated image of said color chart image and said reference image from image information read from said color calibration film; display control means for transmitting said simulated image to said monitor; and a control panel for controlling said image information correcting means while viewing said simulated image of said color image and said reference image being displayed simultaneously on said monitor so as to obtain appropriate quality in said simulated image of said color chart image and said reference image displayed on said monitor.
Claim 3
Dependent Claim
46 words
A monitor adjusting system as claimed in claim 1, further comprising: a density calibration film including a density image corresponding to a reference density and a reference image comprised of a natural image of a photographic subject such as a human subject and a landscape subject.
Claim 4
Dependent Claim
25 words
A monitor adjusting system as claimed in claim 2, wherein said color calibration film and said density calibration film are constructed as a single film.
Claim 5
Dependent Claim
208 words
A monitor adjusting system for an image printer operable to obtain an exposure condition based on image information picked up by an image sensor from a film and having a monitor for displaying a simulated image of a finished photographic print produced by using the exposure condition, the system comprising: a color calibration film including a color chart image having a plurality of separate areas having different colors from each other and a reference image comprised of a natural image of a photographic subject such as a human subject and a landscape subject; image information correcting means for producing a simulated image of said color chart image and said reference image from image information read from said color calibration film, and further producing actual information concerning the color to be corrected and correction content information; display control means for simultaneously displaying on said monitor said simulated image of said color chart image and said reference image, said actual information and said correction content information; and a control panel for controlling said image information correcting means while viewing said simulated image being displayed on said monitor so as to obtain appropriate quality in said simulated image of said color chart image and said reference image displayed on said monitor.
Claim 6
Dependent Claim
208 words
A monitor adjusting system for an image printer operable to obtain an exposure condition based on image information picked up by an image sensor from a film and having a monitor for displaying a simulated image of a finished photographic print produced by using the exposure condition, the system comprising: a color calibration film including a color chart image having a plurality of separate areas having different colors from each other and a reference image comprised of a natural image of a photographic subject such as a human subject and a landscape subject; image information correcting means for producing a simulated image of said color chart image and said reference image from image information read from said color calibration film, and further producing actual information concerning the color to be corrected and correction content information; display control means for simultaneously displaying on said monitor said simulated image of said color chart image and said reference image, said actual information and said correction content information; and a control panel for controlling said image information correcting means while viewing said simulated image being displayed on said monitor so as to obtain appropriate quality in said simulated image of said color chart image and said reference image displayed on said monitor.
