First Claim
1. An image forming method for forming visual image referred image data by subjecting captured image data, which have been recorded by an image-capturing device, to predetermined image processing of optimization to form an image for viewing on an output medium, comprising:
- identifying a type of the image-capturing device;
generating a scene-referred image data by subjecting the image data, obtained by photographing a subject having a reflection density of 0.7, to normalizing processing for each type of the image-capturing device, wherein the normalizing processing ensures that the reflection density on the output medium becomes 0.6 through 0.8;
optimizing conditions of the predetermined image processing using the scene-referred image data to obtain optimized image processing conditions;
storing the optimized image processing conditions for each type of the image-capturing device;
subjecting the image data obtained by applying the optimized image processing conditions to gradation compensation processing, which ensures that the average value of the image data is outputted on an output medium to have the reflection density of 0.6 through 0.8 and γ
values of the leg (shaded portion) and the shoulder (highlighted portion) are smaller than that of the middle portion of the outputted image, and outputting the image data having been subjected to the gradation compensation processing.

Abstract
An image forming method for forming visual image referred image data by subjecting captured image data to predetermined image processing of optimization. The method has the steps of: identifying a type of the image-capturing device; generating a scene-referred image data by subjecting the image data, obtained by photographing a subject having a reflection density of 0.7, to normalizing processing so that the reflection density on the output medium becomes 0.6 through 0.8; optimizing conditions of the predetermined image processing using the scene-referred image data; storing the optimized image processing conditions for each type of the image-capturing device; subjecting the image data to gradation compensation processing, which ensures that the average value of the image data is outputted to have the reflection density of 0.6 through 0.8 and γ values of the leg and the shoulder are smaller than that of the middle portion.
