摘要： An optical device guides propagating light to exit from a desired side surface of a substrate while maintaining sufficient power within a limited size of the substrate and which facilitates adjustment of a mount position of a light-receiving element by increasing allowable tolerance of the mount position of the light-receiving element. The optical device has a substrate, a light propagating direction path formed in the substrate, and a reflection groove formed in an output-side of said light propagating direction path in the substrate. A side wall of the reflection groove is formed to become a convex reflection surface in relation to light which enters from the light propagating direction path, and the light output from the light propagating direction path undergoes total reflection on a side wall forming the reflection surface and lets the reflected light exit from a predetermined side surface of the substrate while enlarging an image.

摘要： An image is divided into blocks and coded by matching each block with a pattern having either a single region, or two or more regions defined by internal edges. The coded value of the block includes a pattern identifier, and a single pixel value for each region in the matching pattern. The coded image is decoded by constructing blocks divided into regions according to the pattern identifiers, and filling each region with the given single pixel value. The decoded blocks may be the same size as the blocks in the original image, or smaller, in which case the decoded image is reduced, or larger, in which case the decoded image is enlarged.
