ABSTRACT:
An image sensing apparatus which performs fast data processing without suffering an increased manufacturing cost. The image sensing apparatus senses an object and produces an image data signal screen-by-screen. In one embodiment, an image sensing apparatus for producing an image data signal includes an image sensing unit, a signal processor, a main buffer memory, and an image data processing circuit. A first group of processed pixels having the size of a first matrix is stored in the main buffer memory. The image data processing circuit receives a second group of pixels having the size of a second matrix from the first group stored in the main buffer memory. Included in image data processing circuit is a sub buffer which is initially filled with the second group of pixels. As pixels are processed and removed from the sub buffer, a third group of pixels is provided from the main buffer which is equal in size to a horizontal row or a vertical column from the second group.
