Abstract
An image color determining device. A ground color presence detecting section determines the presence of a ground color of a target image based on image data relating to the target image. A ground color region specifying section specifies a ground color region in a color space when it is determined that the ground color is present. The ground color region determining section determines whether or not the image data to be determined is a ground color region based on the specified ground color region. The ground color replacing section replaces the image data determined as the ground color region with a predetermined color.
Claims17
An image color determining device comprising:
- a ground color presence detecting section for determining a presence of a ground color of a target image based on image data relating to the target image;
- a ground color region specifying section for specifying a ground color region in a color space when it is determined that the ground color is present by the ground color presence detecting section;
- a ground color determining section for determining whether or not the image data to be determined is a ground color region based on the ground color region specified by the ground color region specifying section;
- and
- a ground color replacing section for replacing the image data determined as the ground color region by the ground color region determining section with a predetermined color, wherein
- the ground color presence detecting section counts the number of constituting units of the image data for every color region on a two-dimensional color plane divided into a plurality of color regions, and determines the presence of the ground color using the counted result, and
- the ground color region specifying section specifies the ground color region based on three-dimensional distribution of the constituting units in the color region corresponding to the around color in the color space when the ground color presence detecting section determines that the ground color is present.
A method for determining an image color, comprising the steps of:
- a ground color presence detecting step of determining a presence of a ground color of a target image based on image data relating to the target image;
- a ground color region specifying step of specifying a ground color region in a color space when it is determined that the ground color is present in the ground color presence detecting step;
- a ground color determining step of determining whether or not the image data to be determined is a ground color region based on the ground color region specified in the ground color region specifying step;
- and
- a ground color replacing step of replacing the image data determined as the ground color region in the ground color region determining step with a predetermined color, wherein
- the ground color presence detecting step includes counting of the number of constituting units of the image data for every color region on a two-dimensional color plane divided into a plurality of color regions, and determination on the presence of ground color using the counted result, and
- the ground color region specifying step includes specification of the ground color region based on three-dimensional distribution of the constituting units in the color region corresponding to the ground color in the color space when it is determined that the ground color is present in the ground color presence detecting step.
