Apparatus and method for generating catalog image and program therefor
First Claim
Patent Images
1. A catalog image generation apparatus comprising:
- image generation means for generating, from image data representing an image, a reference shadow image wherein a main subject of the image has a reference shadow lightness, a reference highlight image wherein the main subject has a reference highlight lightness, and a desired lightness image wherein the main subject has a desired lightness, and for generating from the image data at least one first intermediate lightness image having lightness that is appropriately perceived by human vision to evenly divide the lightness between the reference shadow image and the desired lightness image, and at least one second intermediate lightness image having lightness that is appropriately perceived by human vision to evenly divide the lightness between the reference highlight image and the desired lightness image; and
catalog image generation means for generating a catalog image in which the reference shadow image, the at least one first intermediate lightness image, the desired lightness image, the at least one second intermediate lightness image, and the reference highlight image are arranged.

Abstract
A catalog of images whose lightness has been changed in accordance with human vision is generated. For this purpose, a first image having reference shadow lightness, a second image having reference highlight lightness, a third image having desired lightness, a fourth image having lightness that is visually perceived to evenly divide the lightness between the first image and the third image, and a fifth image having lightness that is visually perceived to evenly divide the lightness between the third image and the second image are generated. The first to fifth images are included in a catalog image.

6. A catalog image generation method comprising the steps of:
-
generating, from image data representing an image, a reference shadow image wherein a main subject of the image has a reference shadow lightness, a reference highlight image wherein the main subject has a reference highlight lightness, and a desired lightness image wherein the main subject has a desired lightness; generating, from the image data, at least one first intermediate lightness image having lightness that is appropriately perceived by human vision to evenly divide the lightness between the reference shadow image and the desired lightness image, and at least one second intermediate lightness image having lightness that is appropriately perceived by human vision to evenly divide the lightness between the reference highlight image and the desired lightness image; and generating a catalog image in which the reference shadow image, the at least one first intermediate lightness image, the desired lightness image, the at least one second intermediate lightness image, and the reference highlight image are arranged. - View Dependent Claims (10, 11)

7. A non-transitory computer-readable recording medium storing a program for causing a computer to execute a catalog image generation method, the program comprising the procedures of:
-
generating, from image data representing an image, a reference shadow image wherein a main subject of the image has a reference shadow lightness, a reference highlight image wherein the main subject has a reference highlight lightness, and a desired lightness image wherein the main subject has a desired lightness; generating, from the image data, at least one first intermediate lightness image having lightness that is appropriately perceived by human vision to evenly divide the lightness between the reference shadow image and the desired lightness image, and at least one second intermediate lightness image having lightness that is appropriately perceived by human vision to evenly divide the lightness between the reference highlight image and the desired lightness image; and generating a catalog image in which the reference shadow image, the at least one first intermediate lightness image, the desired lightness image, the at least one second intermediate lightness image, and the reference highlight image are arranged. - View Dependent Claims (12, 13)
