Abstract
There is provided an image processing apparatus including an image acquisition unit that obtains color image data composed of wavelength components in a visible light region only, and monochrome image data which does not contain the wavelength components in the visible light region and which is composed of wavelength components in other than visible light region only, a color information extraction unit that extracts color information from the color image data, a luminance information extraction unit that extracts luminance information from the monochrome image data, and a synthesis unit that synthesizes the extracted color information and the extracted luminance information to generate composite image data.
Claims11
An image processing apparatus comprising:
- circuitry that includes an RGB color filter and which is configured to
- remove wavelength components that are not in a visible light region from color image data to produce filtered color image data composed of only wavelength components in the visible light region;
- remove wavelength components that are in the visible light region from monochrome image data to produce filtered monochrome image data composed of wavelength components not in the visible light region;
- decompose the filtered color image data into luminance information and color difference information;
- extract only the color difference information associated with the filtered color image data and not the luminance information associated with the filtered color image;
- output only the extracted color difference information and not the luminance information associated with the filtered color image;
- extract luminance information associated with the filtered monochrome image data;
- output the extracted luminance information associated with the filtered monochrome image data;
- and
- synthesize the outputted color difference information and the outputted luminance information to generate composite image data.
An image processing method comprising:
