摘要:
An image capturing apparatus includes a first image sensor unit, a second image sensor unit, and a spatial frequency reduction unit. The first image sensor unit is capable of subjecting an object image formed by an imaging lens to a photoelectric conversion to output a first image signal having a first resolution and constituted by a first number of colors. The second image sensor unit is capable of subjecting the object image formed by the imaging lens to a photoelectric conversion to output a second image signal having a second resolution that is lower than the first resolution and constituted by a second number of colors that is larger than the first number of colors. The spatial frequency reduction unit reduces a spatial frequency of the object image formed on a light receiving surface of the second image sensor unit by the imaging lens.

A mixing ratio database stores information regarding a mixing ratio of plural materials for producing a color corresponding different color chart IDs. A plurality of pieces of color chart spectral information under determination illumination light are calculated using a plurality of pieces of spectral information of spectral reflection factors contained in a color chart and spectral information of the determination illumination light which is information of illumination light used for color chart determination. One of the calculated plural pieces of color chart spectral information which most closely matches spectral information of a subject is determined. A color chart ID which identifies the determined piece of color chart spectral information is output, and information of a mixing amount of each of the plurality of materials for the output color chart ID is also output based on the information stored in the mixing ratio database.

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.

The image processing system is applied to dentistry, for example, and performs photography of the teeth of a patient while causing a plurality of illumination light LEDs of different wavelengths to emit light by means of a photography device when producing a crown repair or denture of the patient, whereby image data are acquired. The image data are transmitted to a dental filing system constituting a processing device where color reproduction data are determined through computation. In addition, color reproduction data are transmitted to the dental technician's office via a public switched network. Therefore, a repair material compound ratio calculation database is searched and the compound data for a material that matches the hue of the patient's teeth are found, whereby a crown repair or denture or the like that very closely matches the color of the patient's teeth is produced.

A color conversion processing execution portion 114 implements color conversion processing on an input image signal, and outputs a color conversion-processed display image signal to an image display unit. Color conversion characteristic information required for the color conversion processing performed by the color conversion processing execution portion 114 is gathered by a characteristic information gathering portion 106. A color conversion processing method selection portion 112 selects an optimum color conversion processing method from among a plurality of candidate color conversion processing methods that can be executed by the color conversion processing execution portion 114 on the basis of the input image signal and the input color conversion characteristic information. A display image signal caused as a result of the color conversion processing is output to a monitor display device 140.
摘要:
A video signal processing device which processes a video signal input into a display monitor inputs illumination profile information relating to an illumination spectral characteristic of a light source and monitor profile information relating to a display profile of the display monitor. A video signal conversion unit performs color conversion processing on the input video signal on the basis of the illumination profile information and monitor profile information, and outputs a video display signal to the display monitor. As a result, color correction is performed on a video image displayed on the display monitor.

An image storage portion 31 stores image data that is input. An outline detecting portion 32 detects an outline of tooth that is the object of color measurement in the image based on the image data. A specular reflection region detecting portion 33 detects the position of a specular reflection region in the tooth that is the object of color measurement based on the data of each pixel that constitutes the image. A rectangular region setting portion 34 sets an analysis region to become the object of analysis processing in the image based on the position of the specular reflection region that is detected by the specular reflection region detecting portion 33. In accordance with the present invention, it is possible to avoid setting an analysis region in a specular reflection region when setting an analysis region, that is the object of analysis processing of an image, in the image.

An image forming apparatus includes a recording head unit in which a plurality of recording heads are arranged in substantially the same direction as the arranging direction of recording elements such that an overlapped region is formed between the heads, a set angle/overlapped region detector which detects the width of the overlapped region of each of the plurality of recording heads from a predetermined test chart printed using the recording head unit, and an image data distributor which distributes image data input to each of the plurality of recording heads, in accordance with the detected width of the overlapped region between the heads. This apparatus achieves an effect of eliminating density unevenness in the head overlapped region only by rough head alignment.
