Abstract: A bar-code field detecting apparatus first differentiates, in X and Y directions, image data of a document including a bar code, the position of which is not determined. It then expands each of the differential images in the direction opposite to the direction in which the image data is differentiated. Expanded images are subjected to bar-code field detection.

Abstract: In an apparatus for detecting an address region on postal matter, an image having address information of the postal matter is converted to a digital signal, and a region associated with the digital signal is found. The associated region is converted to rectangular data indicating a rectangular region circumscribed with the associated region. The rectangular data is subjected to predetermined processing and compared with already known information, thereby easily and exactly effecting address region judgment.

Abstract: A character reading apparatus including functions for storing size information of an object to be read, an inherent image included in the object, and position information about a read area of the object, from which information is to be read, in advance, in correspondence with each other, functions for scanning the object and obtaining an actual image, functions for measuring a size of the object, functions for comparing an original image corresponding to the size of the object, stored in the storing functions, with the actual image of the object, obtained by the scanning functions, on the basis of the measurement result obtained by the measuring functions, functions for, when the comparing functions determined that the original image coincides with the actual image, determining the position information about the read area, stored in correspondence with the actual image, as a read area of the object, and functions for reading a character from an original image of the read area determined by the read area deter

Abstract: A character reading apparatus optically reads a recording medium and stores an image information as multi-value image in the multi-value image memory (3). The image information stored in the multi-value image memory (3) is scanned in the horizontal direction (character line direction). The maximum value for the pixel data of each line is detected by maximum density value extraction unit (4). When all the scanning in the horizontal direction has been completed, maximum value data (A1) is obtained. Differential data (A2) is obtained by differentially processing this maximum value data (A1), and a domain is obtained as the height of the character line. When the height of the character line have been obtained, the image information of the multi-value image memory (3) is scanned in the vertical direction. As in the horizontal direction, the maximum values for each scan in the vertical direction are extracted by maximum density value extraction unit(4).

Abstract: A video recording and playback device with a built-in video camera includes an outer case having the same profile as that of a tape cassette that can be inserted into an exiting stationary video tape recorder.

Abstract: Disclosed is a tape loading device of a video tape recorder provided with an inclined video head cylinder and a capstan. The tape loading device includes a first guide member for feeding a tape on a horizontal path to the inclined video head cylinder, a second guide member for taking out the tape from the video head cylinder, and a third guide member for guiding the tape having passed the second guide member. The first, second and third guide members move along the video head cylinder and are in contact with the internal surface of the tape during the tape loading operation. The tape loading device further includes a fourth guide member for restoring the tape from an inclined path to a horizontal path during the tape loading operation by contacting the external surface of the tape, and an auxiliary inclined member for moving the tape inwardly during the tape loading operation so that the tape may be restored from an inclined path to a horizontal path.
