    摘要: Input image data inputted in an image block of m pixels×n pixels is changed in the size of the image block; image data of the image block changed in size is subjected to compression processing; compressed image data obtained by the compression processing is subjected to expansion processing to generate restored image data in the m-pixel×n-pixel image block; and whether or not the size of the image block is further changed is judged based on the strength of the correlation between the restored image data and the input image data. The compression processing is performed on the image data while change in size of the image block is repeated until the correlation between the restored image data and the input image data is strong, thereby making it possible to perform compression processing on the image data of the input image at a high compression ratio while maintaining the image quality of the restored image.

The method includes the step of forming a conductor layer having a step portion on the surface of a substrate. The step portion includes a lateral face which surrounds the lower surface of the step portion to form a closed loop. After the conductor layer has been formed on the surface of the substrate, a monocrystalline film is formed directly on the substrate. Specifically, the film is formed on the lower surface of the step portion, while a DC potential is applied to the conductor layer.
