Abstract: PROBLEM TO BE SOLVED: To provide an improved system and method which buffer and access image data. SOLUTION: Provided are a method and apparatus for buffering 2-dimensional graphical image data to be supplied to a scrolling display controller. A 2-dimensional, circularly addressed data buffer is used to store a portion of an entire image. The data buffer is larger than the amount of data displayed at one time. A user enters scrolling commands and the display scrolls around the data initially in the buffer. new data is loaded into the buffer as the displayed data approaches the edge of the buffered data.

Abstract: PROBLEM TO BE SOLVED: To improve the image processing in a digital camera. SOLUTION: A method is provided for storing a plurality of still images for forming a panorama image, as follows. A first image forming a part of a series of images for forming the panorama image is received and stored in a memory. When one or more images following the first image are received, one or more panorama parameters between the present image and the previous image stored in the memory are calculated, and the present image is stored in the memory, together with the one or more panorama parameters.
