Title: Image processing method, digital camera, and recording medium
Inventor: YANO HITOSHI
IPC: H04N5/232
Filed: 2000-11-15
Abstract: PROBLEM TO BE SOLVED: To provide an image processing technology to efficiently utilize a memory. SOLUTION: In this image processing by using a digital camera, a pixel matrix Hi expressing a photographed image data is divided into two matrixes H1 and H2 in the X direction (row direction) and they are image-processed by using a space filter Fi. In this case, a part of the image data is temporarily stored in a buffer memory, and the matrix H1 is image-processed while the space filter Fi is raster-scanned for every one pixel (directions of D1, D2, and D3). The matrix H2 is also image-processed in the same manner as the matrix H1 while the space filter is raster-scanned. Thus, since a buffer area expressed by a matrix Hb that has a smaller length in the row direction than a length (n) in the row direction of the matrix Hi is used for image processing, a memory can be efficiently utilized.
