摘要： PROBLEM TO BE SOLVED: To implement a color correction method for allowing adjustment of gray balance or a color shift which are incident to initialization and variation with time of an image output device, and replacement of a consumable material with an accuracy desired by a user just by means of a visual estimation without using a measurement instrument or an image input device by the user. SOLUTION: The color adjustment method outputs a first primary color chart which is obtained by an image recording apparatus using predetermined gradation data of the first primary color and a chart which is obtained by fixing the gradation data of the first primary color and varying gradation data of a second and a third primary colors respectively, acquires a reference density correction value by comparing the first primary chart with a first primary color reference chart in which the first primary density is varied, acquires a gray balance correction value by comparing a gray reference chart corresponding to the reference density correction value with the outputted chart, thereby performing color adjustment of the image recording apparatus with the reference density correction value and gray balance correction value.

摘要： PROBLEM TO BE SOLVED: To realize a color chart for calibrating an image processing apparatus from which effects by characteristics of a recording head, etc., can be eliminated as much as possible and which can be corrected later so as to highly accurately adjust a gray balance, gradation characteristics, etc., to any image output unit. SOLUTION: This color chart for calibrating or adjusting the gray balance and gradation characteristics at the image output unit has a patch array 100 of a plurality of patches of the same color and the same density embedded to an arbitrary position of the chart.

摘要： PROBLEM TO BE SOLVED: To provide the spectral measurement system which is small-sized and easily used and its signal processing method. SOLUTION: The system includes a color light information extraction part 120 which extracts specific color light information from light made incident on the spectral measurement system, a photoelectric conversion part 130 which converts the color light information extracted by the color light information extraction part into an electric signal by a photoelectric converting element, a database part 160 which holds statistical feature quantities derived from spectral characteristics measured by the spectral measurement system, and a signal processing part 140 which processes the electric signal outputted from the photoelectric conversion part to estimate spectral characteristics, and the spectral characteristics are estimated from the photoelectrically converted electric signal through the signal processing of the signal processing part by using statistical feature quantities held at the database part.

摘要： PROBLEM TO BE SOLVED: To provide an image quality evaluation device by which evaluation values can be easily obtained with high accuracy from one test chart. SOLUTION: Since the image quality evaluation device provides two image quality evaluation values or more with respect to at least one of the gradation and the color characteristics obtained on the basis of an electric signal obtained resulting from a picked up image of the test chart G placed on a stage 5, it is not required to prepared different test charts from evaluations as by a conventional technology. Therefore the image quality evaluation device performs evaluation more easily with high accuracy, without using a wrong test chart.

摘要： PROBLEM TO BE SOLVED: To efficiently retrieve and display a target image by retrieving images similar to the object image to be retrieved from a database having a directory structure. SOLUTION: A personal computer 10 and a film scanner 30 are connected to a server 20 with large storage capacity through a network N and the image database is structured on the server 20. To retrieve a specific image from the database, multiple images, e.g. images in the image database are statistically classified into the determined number of clusters and images representing the respective clusters are displayed on the screen on the personal computer 10. The relative distances in feature quantity between an image selected out of them and other images are found to calculate similarities. The similarities are set larger and larger as the distances are shorter and shorter, and an image which is registered more recently is retrieved with higher priority. Thumbnail images are displayed in the decreasing order of the similarities. Consequently, the user can obtain a desirable image faster.

摘要： PROBLEM TO BE SOLVED: To adjust deviation of gray balance due to initial setting and deterioration due aging of image-outputting equipment, and the replacement of ink sheet, toner, and image reception paper by a simple visual measurement with accuracy that a user wishes and without using measurement equipment or image-inputting equipment or by the user. SOLUTION: A primary color Y is made to change in the direction of ordinates at a first density change rate, and at the same time, a secondary color C is changed in the direction of abscissas at a second density change rate. A color patch image formed by combining the primary and secondary colors is arranged in the directions of ordinates and abscissas, the color path image is formed, based on a specific operation processing using coordinates in the direction of ordinates and abscissas that have been recorded in advance; and a color matrix chart 1 is formed by arbitrarily setting the first and second density change rates when creating the color matrix chart, by forming the index of the color patch image led from the first and second density change rates at a prescribed position.
