Abstract: An image processing device is provided to reduce a thinning process time. Binarization data are divided into predetermined image blocks and stored in an input storing unit(120). A thinning unit(140) parallel thins the divided image blocks. An input switch unit(130) connects the input storing unit and the thinning unit. An output storing unit(160) stored the thinned image blocks. An output switch unit(150) connects the thinning unit and the output storing unit. An image data reconfiguration unit(170) combines the thinned image blocks stored in the output storing unit and reconfigures the blocks as thinned image data.

Abstract: A chain code generating apparatus and method are provided to generate the chain code for an interest decoding target from an input image in real-time only with a small hardware device, thereby reducing the overload of a total image processing system and maximizing the efficiency of the total image processing system. A chain code generating apparatus includes an image input unit(110), an image storage unit(120), a code generation unit(130), a code storage unit(140), and a transmission unit(150). The image input unit receives image signals from a camera(200), converts the received image signals into digital image signals, and divides and outputs sync signals from the image signals. The image storage unit stores image data corresponding to an effective image section by frame out of the digital image signals on the basis of the sync signals. The code generation unit reads the image data stored in the image storage unit to perform the outline searching of an interest decoding area, and generates the chain code in correspondence to location correlation between adjacent pixels forming the outline of the interest decoding area according to a searching result. The image storage unit includes a first buffer memory and a second buffer memory, and stores the image data corresponding to the effective image section alternately in the first buffer memory and the second buffer memory whenever a frame is changed. When the image data is stored in one of the first buffer memory and the second buffer memory, the code generation unit reads image data from the other of the first buffer memory and the second buffer memory to generate the chain code.
