  • Patent number: 7574042
    Abstract: An image processing apparatus includes a photographing condition estimation unit for estimating a photographing condition of the input image based on photometric information and focal information. A Y/C separation unit separates the input image into a luminance signal and a color difference signal; a luminance correction unit extracts an edge from the luminance signal and corrects the luminance signal by a gradation conversion curve; a color difference correction unit corrects the color difference signal based on luminance signals obtained before and after the gradation correction and a theoretical limit characteristic of color reproduction; a skin color correction unit performs skin color correction depending on the photographing condition; and a Y/C synthesis unit synthesizes the luminance signal and the color difference signal obtained after the correction. Gradation correction is performed on the input image such that appropriate hue and saturation are achieved while emphasizing a main object.

    Abstract: An image processing system is used for dentistry. Upon creating a false tooth of a patient (59), a plurality of illuminating light of LEDs with different wavelengths emit light and a photographing apparatus (1A) photographs a tooth portion of the patient (59), thereby obtaining image data. The image data is sent to a dentistry filing system (2A) serving as a processing apparatus, and color reproducing data is obtained by calculation. The color reproducing data is sent to a dentistry factory (55) via a public line. Data is searched from a database (56) for calculating a ceramic compounding ratio, compound data of the ceramic false tooth is obtained, matching the color of the tooth portion of the patient (59), and the false tooth approximate to the tooth color of the patient (59) is created.
