ABSTRACT:
When images of several frames captured by an image sensing device such as an electronic still-video camera are displayed on a display unit, the images are made easier to view by rotating each image in conformity with the inclination of the horizontal scanning direction of the camera, with respect to the horizontal, which prevailed when the image was captured. Several frames of compressed image data stored in a memory card or external storage unit are decompressed by a compression/expansion circuit and then stored in a compression/expansion memory. The stored compressed image data thus is read out by a thin-out/rotation circuit and the data is then thinned out, processed for movement to a designated position and processed for rotation based on angle data. The processed image data is stored in a display memory. Under the control of a display control circuit, the display unit displays the image data that has been stored in the display memory.
