摘要:
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.
摘要:
An object is to carry out color correction in a highly accurate manner on images acquired by various digital cameras and scanners. A color correction apparatus includes a determining unit configured to determine whether or not preprocessing for removing the effect of previously-performed color correction is required for a reference image that is used for a reference of color correction and a color correction target image on which color correction is to be carried out; a preprocessing unit configured to carry out preprocessing on a reference image and a color correction target image that is determined by the determining unit as requiring preprocessing and output a preprocessed image; a color-correction processing unit configured to acquire a reference image or color correction target image that is not preprocessed if the determining unit determines that the reference image or color correction target image does not require preprocessing or to acquire a preprocessed reference image or color correction target image if the determining unit determines that the reference image or color correction target image requires preprocessing, and to correct the color correction target image on the basis of the acquired reference image.

An image processing system includes a photographing apparatus and a processing apparatus. The photographing apparatus includes LEDs for emitting light with characteristics of spectroscopic distributions varied in a visible light area, an image pick-up device unit which picks-up a subject image that is illuminated by the LEDs and is formed by an image pick-up optical system and which outputs an image signal, and a control unit. The control unit sequentially lights-on the LEDs upon an instruction for photographing a subject spectroscopic image being input from an operating switch, picks-up the image, and thus controls the operation for capturing subject spectroscopic images. The processing apparatus includes a calculating device which performs a desired image calculation based on the image signal.

An image processing system includes a photographing apparatus (1) and a processing apparatus (2). The photographing apparatus (1) includes six LEDs (6a to 6f) for emitting light with characteristics of spectroscopic distributions varied in a visible light area, a monochrome-type CCD (8) which picks-up a subject image that is illuminated by the LEDs (6a to 6f) and is formed by an image pick-up optical system (7) and which outputs an image signal, and a CPU (18) which sequentially lights-on the LEDs (6a to 6f) upon an instruction for photographing a subject spectroscopic image being input from an operating switch (14), picks-up the image by the CCD (8), and thus controls the operation for capturing 6-primary-color subject spectroscopic images. The processing apparatus (2) includes a calculating device (21) which captures the 6-primary-color subject spectroscopic images photographed by the photographing apparatus (1) to create a display signal for color reproduction at the high fidelity level, and a display (22) which displays the display signal created by the calculating device (21).
