Abstract
An apparatus and a method for temporary storage of image-encoding data are provided. The apparatus for temporary storage of image-encoding data is utilized for high-resolution image encoding, wherein the apparatus includes an image sensing unit, a storage unit, and an encoding unit. The image sensing unit creates a plurality of frame data in successive order. Each frame data is composed of a plurality of macroblock row data. The storage unit includes a first storage portion and a second storage portion. The capacities of the first storage portion and the second storage portion are both a positive integral multiple of the size of the macroblock row data. The storage unit receives the macroblock row data from the image sensing unit and writes the macroblock row data into one of the first storage portion and the second storage portion. When the encoding unit reads the written macroblock row data from one of the first storage portion and the second storage portion, the storage unit simultaneously receives new macroblock row data from the image sensing unit and writes the new macroblock row data to the other one of the first storage portion and the second storage portion. The design of …
