A photographing apparatus includes a carriage, a light source, and a camera. The carriage moves in a travel direction. The light source is mounted on the carriage. The camera is attached to the carriage and configured to perform photography. A normal direction is defined orthogonal to the travel direction and a vertical axis. The camera faces a camera direction that is rotated about the vertical axis with respect to the normal direction.

Photographing apparatus with mobile carriage and photographing method therefor

An article recognition device includes an image interface, a distance information interface, a support unit, and a processor. The support unit supports an article at a height equal to or greater than a minimum discrimination distance of a distance sensor from a reference plane of the distance sensor and includes a member of which a distance cannot be measured by the distance sensor. The processor acquires a captured image capturing the article supported by the support unit through the image interface, acquires distance information measured by the distance sensor toward the reference plane through the distance information interface, extracts an area having a height equal to or greater than the minimum discrimination distance from the reference plane as an article area of the article from the captured image based on the distance information, and recognizes the article from an image of the article area.

Article recognition device

An image processing system includes a camera interface and a processor. The camera interface acquires a captured image from at least one camera that images an article. The processor acquires a basic shape of the article and acquires an image captured with imaging parameters corresponding to the basic shape from the at least one camera through the camera interface.

An autonomous inventory tracking apparatus includes an image acquisition unit configured to acquire an image, and a processor configured to detect a calibration plate in the image acquired from the image acquisition unit, calculate a color correction value for the image according to a color block of the calibration plate, the color block matching a reference value, correct color in the image using the calculated color correction value to provide a color-corrected image, and perform commodity recognition processing on the color-corrected image so as to identify the commodity in the image acquired from the image acquisition unit.

Image processing apparatus and image processing method

According to one embodiment, a code recognition device includes a reader, a processor for region detection, for first extraction, and for second extraction. The reader photographs a code image. The processor detects a code region and a letter region included in the code image from the code image photographed by the reader. The processor extracts first code information indicating the code image from the code region. The processor also extracts second code information indicating the code image from the letter region.

When one or both of color conversion data for chromatic colors and color conversion data for achromatic colors are rewritten, attribute information of the color conversion data for chromatic colors or the color conversion data for achromatic colors is updated and this attribute information is displayed on a display.

Image processing apparatus

Color conversion data used in converting an image signal into color information represented by color materials is saved in a color-conversion-data saving unit and, when the color conversion data is rewritten, before rewriting of the color conversion data, the color conversion data is copied to an area different from an area in which the color conversion data is rewritten in the color-conversion-data saving unit.

An image processing apparatus comprising an edge detection circuit which detects an edge from pixel data, a pseudo-halftone processing circuit which performs pseudo-halftone processing of the pixel data and outputs pseudo-halftone data, and a data synthesis circuit which synthesizes pixel data based on the pseudo-halftone data with the pseudo-halftone data at positions corresponding to the edge which the edge detection circuit detects to output the pseudo-halftone data having pixel data at the edge positions. With the apparatus applied, a print effected with the pseudo-halftone data has a high quality outline with no jaggedness.
