Abstract
An apparatus provides a unit capable of improving gradation characteristics of a plurality of images (crop images) even in a case where a plurality of users individually performs cropping (cutting out) on a distributed image, calculates a target gradation range based on histograms of the regions cropped by the plurality of users, and executes gradation conversion based on an overlapping ratio of the plurality of target gradation ranges.
Claims15
An apparatus comprising:
- at least one processor;
- and
- a memory that is coupled to the at least one processor and stores one or more computer-readable instructions, wherein the computer-readable instructions cause, when executed by the at least one processor, the at least one processor to operate to:
- allow users to specify a plurality of arbitrary image regions;
- crop out and output each of the respective arbitrary image regions from an entire image acquired by imaging an object;
- acquire pieces of information indicating gradation of the respective arbitrary image regions;
- and
- change a gradation conversion characteristic of the entire image based on the acquired pieces of information,
- wherein the information indicating gradation is information indicating a target gradation range in which pixels of a predetermined rate or more are included, from among gradation ranges of the arbitrary image regions.
6 more elements
A method comprising:
- allowing users to specify a plurality of arbitrary image regions;
- cropping out and outputting each of the respective arbitrary image regions from an entire image acquired by imaging an object;
- acquiring pieces of information indicating gradation of the respective arbitrary image regions;
- and
- changing a gradation conversion characteristic of the entire image based on the acquired pieces of information,
- wherein the information indicating gradation is information indicating a target gradation range in which pixels of a predetermined rate or more are included, from among gradation ranges of the arbitrary image regions.
3 more elements
A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute a method comprising:
- allowing users to specify a plurality of arbitrary image regions;
- croppinq out and outputting each of the respective arbitrary image regions from an entire image acquired by imaging an object;
- acquiring pieces of information indicating gradation of the respective arbitrary image regions;
- and
- changing a gradation conversion characteristic of the entire image based on the acquired pieces of information,
- wherein the information indicating gradation is information indicating a target gradation range in which pixels of a predetermined rate or more are included, from among gradation ranges of the arbitrary image regions.
