Abstract
An image processing device including: a color space selection unit that selects a color space based on designated color information; and a region specifying unit that specifies a region that includes a color that matches the color that is shown by the color information designated in the color space from a color region specified image that is provided for color region specification.
Claims11
An image processing device comprising:
- a color space selection unit that selects a color space based on designated color information;
- and
- a region specifying unit that specifies a region that includes a color that matches a color that is shown by the color information designated in the color space from a color region specified image that is provided for color region specification,
- wherein the color space selection unit selects one of a color space that includes color difference information or a color space that includes hue information, and
- wherein the color space selection unit selects a color space that includes hue information in a case when a saturation of the color region specified image is equal to or greater than a threshold value, and selects a color space that includes color difference information in a case when the saturation is lower than the threshold value.
An image processing method comprising:
- selecting, by use of a color space selection unit, a color space based on designated color information;
- and
- specifying a region that includes a color that matches a color that is shown by the designated color information in the color space from a color region specified image that is provided for color region specification,
- wherein the selecting selects one of a color space that includes color difference information or a color space that includes hue information, and
- wherein the selecting selects a color space that includes hue information in a case when a saturation of the color region specified image is equal to or greater than a threshold value, and selects a color space that includes color difference information in a case when the saturation is lower than the threshold value.
A non-transitory computer readable storage medium having stored thereon a program causing a computer to execute the image processing method comprising:
- selecting a color space based on designated color information;
- and
- specifying a region that includes a color that matches a color that is shown by the designated color information in the color space from a color region specified image that is provided for color region specification,
- wherein the selecting selects one of a color space that includes color difference information or a color space that includes hue information, and
- wherein the selecting selects a color space that includes hue information in a case when a saturation of the color region specified image is equal to or greater than a threshold value, and selects a color space that includes color difference information in a case when the saturation is lower than the threshold value.
