Abstract
An image processing apparatus includes a separating unit, an analyzing unit, a determining unit, and an image correcting unit. The separating unit separates a color image into a foreground image and a background image. The analyzing unit analyzes the foreground image and the background image to acquire a foreground attribute value and a background attribute value. The determining unit determines an image processing coefficient, based on the foreground attribute value and the background attribute value. The image correcting unit corrects the color image, in accordance with the image processing coefficient.
Claims16
An image processing apparatus comprising:
- a separating unit that separates a color image into a foreground image and a background image;
- an analyzing unit that analyzes the foreground image and the background image to acquire a foreground attribute value and a background attribute value;
- a determining unit that determines an image processing coefficient, based on the foreground attribute value and the background attribute value;
- and
- an image correcting unit that corrects the color image, in accordance with the image processing coefficient.
An image processing apparatus comprising:
- a separating unit that separates a color image into one or more foreground images and a background image;
- an analyzing unit that analyzes the one or more foreground images and the background image to acquire one or more foreground attribute values and a background attribute value;
- a determining unit that determines, in accordance with the one or more foreground attribute values and the background attribute value, foreground coefficients, which are image processing coefficients corresponding to the one or more foreground images, and a background coefficient, which is an image processing coefficient corresponding to the background image;
- and
- an image correcting unit that corrects the one or more foreground images in accordance with the one or more corresponding foreground coefficients, corrects the background image in accordance with the background coefficient, and combines the corrected one or more foreground images with the corrected background image.
An image processing method comprising:
- separating a color image into a foreground image and a background image;
- analyzing the foreground image and the background image to acquire a foreground attribute value and a background attribute value;
- determining an image processing coefficient, based on the foreground attribute value and the background attribute value;
- and
- correcting the color image, in accordance with the image processing coefficient.
A computer readable medium storing a program causing a computer to execute a process for image processing, the process comprising:
- separating a color image into a foreground image and a background image;
- analyzing the foreground image and the background image to acquire a foreground attribute value and a background attribute value;
- determining an image processing coefficient, based on the foreground attribute value and the background attribute value;
- and
- correcting the color image, in accordance with the image processing coefficient.
