Abstract

An image processing result display apparatus that is capable of carrying out smooth scrolling. A scrolling direction that will be designated by an operator is predicted based on image data displayed on an LCD. Image data positioned in the predicted scrolling direction is pre-read from an external storage device. Image data is generated by carrying out predetermined image processing on the pre-read image data and is stored in a main memory. A portion of image data displayable on the LCD is read from the image data stored in the external storage device or in the main memory. If image data positioned in the scrolling direction designated by the operator is stored in the main memory, the image data is read from the main memory, and image data positioned in the scrolling direction designated by the operator is generated based on the read image data, and the generated image data is displayed on the LCD.

wherein said predicting step includes determining whether the display layout is a horizontally elongated configuration or a vertically elongated configuration, and predicting that the operator will designate scrolling in a horizontal direction when it is determined that the display layout has a horizontally elongated configuration, and predicting that the operator will designate scrolling in a vertical direction when it is determined that the display layout has a vertically elongated configuration;

wherein a priority order is assigned to the image data pre-read by the pre-reading step;

wherein, when the display layout has a horizontally elongated configuration, image tiles corresponding to the image data pre-read by the pre-reading step adjacent to a right-hand side of an area to be displayed are given priority levels from top to bottom moving rightwards until the right edge of the whole image tiles is reached, then numbering of the priority levels is carried out starting with the left edge of the whole image tiles where the image tiles are numbered from left to right moving downwards, then image tiles positioned one row under the area that is being displayed are numbered from the left edge to the right edge of the whole image tiles, and then numbering continues downwards; and
