Abstract: When an error occurs in decoding of coded data such as a barcode, the error in the decoding of the coded data is analyzed based on an image acquisition status of the coded data in image data acquired by image acquisition performed by an image acquisition section. Then, handling information allowing the coded data to be decoded is provided depending on a result of the analysis.

Abstract: Moving image data output from an image sensing device is input. An image display output unit processes the moving image data and displays it on the display screen of a display as a real-time moving image. A decode processing notification unit displays the moving image data output from the image sensing device on the display screen of the display as a still image for a predetermined time from decoding of the datacode by a decoding unit.

Abstract: When decoding a datacode based on moving image data output from an image sensing device, moving image data output from the image sensing device is input. An image display output unit processes the moving image data and displays it on the display screen of a display as a real-time moving image.

Abstract: A case has a front surface facing an image sensing area, a concave formed on the front surface, and an opening on the bottom of the concave. The case accommodates an area image sensor to image-sense the image sensing area through the opening, and an illumination device to illuminate the entire image sensing area. There are provided a photoelectric converting unit converting an output of the area image sensor into an electric image signal, and an output unit outputs an image signal converted by the photoelectric converting unit to an image processing device. The case also accommodates a lens to form an image of the image sensing area on the area image sensor with a depth of field so as to the image processing device obtain a resolution to enable analysis of a code symbol included in the image signal. A lens side limit position of the depth of field corresponds with the position of the front surface of the case.

Abstract: When obtaining an ID code from a user who holds out an arm to a corresponding merchandise in a noncontact manner, respective information terminal devices accept a registration input of the corresponding merchandise. When accepting the registration input of the corresponding merchandise, registration merchandise information including obtained user identification information and merchandise identification information for identifying the merchandise corresponding to the information terminal device is transmitted to a server device. The server device stores and manages merchandise sales information for the respective ID codes from the registration merchandise information received from the respective information terminal devices. When the ID code is input from a settlement device, the merchandise sales information corresponding to the ID code is transmitted to the settlement device. The settlement device performs the settlement processing based on the merchandise sales information received from the server device.

Abstract: An article code reading device optically reads a code symbol on to an article and specifies the article, and decodes and outputs an article code. An image pickup image part picks up an image of an area of an article, the code symbol of which is read by the article code reading device, and outputs pickup image data. An article registration is executed by searching an article data file for a corresponding price for the article, and an extraction process extracts an exterior characteristic of an article from a the pickup image data outputted by the pickup image part. A consistency is determined between a first data obtained based on the extraction process and a second data obtained based on an output from the article code reading device, and an alarm is generated when it there is not a consistency between the first data and the second data.
