Abstract
An image processing apparatus includes an influence value setting unit that sets an influence value on a pixel of interest in a local region of an image, the influence value being a color difference in the local region, and a color region processing unit that treats the pixel of interest as a pixel in a region of a representative color when a color of the pixel of interest is within a range from the representative color to the threshold value, the threshold value being set such that the threshold value increases as the influence value increases.
Claims10
An image processing apparatus comprising:
- an influence value setting unit that sets an influence value on a pixel of interest in a local region of an image, the influence value being a color difference in the local region, and the local region being a two-dimensional area of a predetermined size smaller than the image;
- and
- a color region processing unit that treats the pixel of interest as a pixel in a region of a representative color when a color of the pixel of interest is within a range from the representative color to a threshold value, the threshold value being set such that the threshold value increases as the influence value increases.
A non-transitory computer readable medium storing a program causing a computer to execute a process for processing an image,
- the process comprising:
- setting an influence value on a pixel of interest in a local region of an image, the influence value being a color difference in the local region, and the local region being a two-dimensional area of a predetermined size smaller than the image;
- and
- treating the pixel of interest as a pixel in a region of a representative color when a color of the pixel of interest is within a range from the representative color to a threshold value, the threshold value being set such that the threshold value increases as the influence value increases.
A method for processing an image, comprising:
- setting an influence value on a pixel of interest in a local region of an image, the influence value being a color difference in the local region, and the local region being a two-dimensional area of a predetermined size smaller than the image;
- and
- treating the pixel of interest as a pixel in a region of a representative color when a color of the pixel of interest is within a range from the representative color to a threshold value, the threshold value being set such that the threshold value increases as the influence value increases.
