Abstract: According to one embodiment, a code reading apparatus includes an image pickup section, a detecting section, a size recognizing section, and a reading section. The image pickup section picks up an image. The detecting section detects, from the picked-up image, a two-dimensional code obtained by converting information concerning a transaction of a commodity. The size recognizing section recognizes the size of the detected two-dimensional code. The reading section reads the information from the detected two-dimensional code if the recognized size of the two-dimensional code is different from the size of a two-dimensional code recognized immediately before the recognition of the size of the two-dimensional code in the same transaction processing.

Abstract: An original image field is successively scanned along each of parallel line paths to detect the image density of the scanned elemental picture area. A plurality of recurring sequences of binary digits or pulses is generated for each of the scanned line paths in synchronism with the scansion of each elemental picture area, thereby forming dot pattern conversion matrices corresponding in number to the number of discrete gradation steps or image densities with the pulses representing the dots in each matrix. The detected image density is used to select a corresponding one of the dot pattern matrices to represent the scanned area with a dot if the latter is present in a specified position in the corresponding matrix by allowing the selected recurring pulse sequence to be delivered to a recording unit which is moved with respect to a recording field in synchronism with the scansion of the original field.
