Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a video coding system, and particularly to a video coding system that monitors the address of a postal item using a video camera or the like and prints a code according to the address on the postal item.

In general, a video coding system uses a scanner, such as a video camera, to pick up addresses written on letters and other postal items that are sequentially sent from a supply unit, and displays images of the addresses on a display unit. The code is displayed on a display unit such as a cathode ray tube, and an operator reads the information and inputs the address information using a keyboard or the like that constitutes a keypad, and a code according to the information is printed on the mail piece.

In this video coding system: 1. Since the display quality of mail addresses displayed on a cathode ray tube or the like determines the performance of a video coding system, improvement in display quality is required in order to increase the throughput of a video coding system.

Here, one way to improve the display quality of the display unit in a video coding system is to increase the number of scanning lines of the cathode ray tube, increase the video frequency, and increase the display resolution to achieve high-density and detailed display. is necessary. Using this means requires an increase in the amount of information to be stored and an increase in the frequency at which the storage section is controlled.

A conventional video coding system includes a supply section that supplies mail pieces one by one to a conveyance path, a scanning section that optically scans the character surface of the mail pieces being conveyed and outputs scanned information, and a scanning section that outputs scanned information by A high-speed, large-capacity storage section into which information is written, memorized, and output as display information, a display section that displays character images according to the display information, and a keypad section that can input code information according to the character information. and a printing unit that prints a code on the mail being conveyed according to the code information.

In other words, in order to improve display quality, conventional video coding systems increase the number of scanning lines on the cathode ray tube, increase the video frequency, and increase the display resolution to achieve high-density and detailed display. Since it is necessary to increase the amount of information read from the storage section within a predetermined time, it is necessary to make the memory element that constitutes the storage section extremely high-speed.
