Abstract
A method to convert line-based pixel data from an imager, e.g. a video camera into block-based pixel data with a minimum of buffer memory size has been achieved. Key of the invention is that as soon pixel data are read-out of a buffer memory, pixel data of the next image are written to the same position of the buffer memory as the pixels, which have been just read-out have been located. While in prior art the buffer memory required a capacity to store two images is, using the method invented, only a capacity to store one image required. A method to convert line-based pixel data for an image application reading-out column-wise has been illustrated in detail. This general method can be used for a multitude of image transformations and image compression methods e.g. for compression of pixel data as JPEG, for mirroring, tilting, rotating etc. of line-based pixel data.
