20080259336 | IMAGE PROCESSING SYSTEM AND CAMERA - An image processing system which 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. A repair material compound ratio calculation database is searched and compound data for a material that matches the hue of the patient's teeth is retrieved, so that a crown repair or denture or the like that very closely matches the color of the patient's teeth can be produced. | 10-23-2008 |
20090021738 | METHOD AND SYSTEM FOR PREDICTING PRINT COLORS - A colorimeter of a profile generator calorimetrically measures a color chart after elapse of a sufficient period of time from printing of the color chart, thereby producing post-dry-down colorimetric values. The colorimeter also calorimetrically measures certain patches selected from the color chart immediately after printing thereof, thereby producing pre-dry-down calorimetric values. Colorimetric value differences between the post-dry-down colorimetric values and the pre-dry-down colorimetric values are calculated. Using the calorimetric value differences and the post-dry-down calorimetric values, device-dependent data are converted into colorimetric values, which represent pre-dry-down device-independent data. The colors of a print prior to dry-down are predicted based on such converted colorimetric values. | 01-22-2009 |
20090168063 | DENTAL COLOR MEASUREMENT TOOL, DENTAL COLOR MEASUREMENT TOOL SYSTEM, AND DENTAL COLOR MEASUREMENT SYSTEM - A dental color measurement tool disposed opposite an opening portion for capturing light from an artificial tooth to undergo color measurement with a color measurement device includes at least one pair of guide posts having an engaging portion corresponding to an engaging portion on the color measurement device side, and an abutment post disposed between the pair of guide posts and having a pointed convex shape to which the artificial tooth can be mounted. The abutment post has a color measurement reference surface in a color measurement light axis direction as the vicinity of a focus position of the color measurement device in a photographing state. When performing color measurement photographing, the artificial tooth is mounted to the abutment post to position the front thereof at the color measurement reference surface. Thus, the artificial tooth can be stably retained at a suitable position with respect to the color measurement device. | 07-02-2009 |
20100027009 | METHOD AND SYSTEM FOR DETECTING SIGNAL COLOR FROM A MOVING VIDEO PLATFORM - The present invention aims at providing a method for detecting a color of a signal light from a moving vehicle such as railroad train. The method includes capturing an image from a camera mounted on the moving vehicle and extracting candidate regions in the image that contain light region. The method further includes classifying the candidate regions as a signal light region or a non-signal light region and identifying the color of the signal light region. | 02-04-2010 |
