摘要:
A digital planetarium apparatus includes an original image generator, an intermediate image generator, and a fish-eye lens. The original image generator is formed of two video projectors and generates semicircular images in display devices inside the respective video projectors. The intermediate image generator optically focuses the two semicircular images generated by the original image generator to thereby generate a circular image. The fish-eye lens projects the circular image generated by the intermediate image generator.

摘要:
In an image processor, multi-level image data are divided into blocks, and compressed in the unit of block. The compressed multi-level image data of a block are converted to compressed bi-level image data without expanding the multi-level image data. For example, the compressed multi-level image data on an image of uniform density are converted to compressed bi-level image data expressed with area gradation. In another image processor, the compressed multi-level image data of a block are converted to compressed multi-level image data, without expanding the multi-level image data. For example, the compressed multi-level image data on an image of bi-level image expressed with area gradation are converted to compressed multi-level image data of a half-tone image.
摘要:
In an image processor, a decider decides based on image data of pixels included in a block whether the block has character attribute of non-character attribute, a first encoder encodes the image data with block truncation coding, and a second encoder encodes the image data which have been encoded by the first encoder. For a block of character attribute, the binarized data binarized by the binarizer are encoded by the first and second encoders. For a block of non-character attribute, the image data are encoded by the first and second encoders without binarization. In a different image processor, it is decide whether image data of pixels in an area consisting of a plurality of blocks are all character, all ground or mixture of character and ground. Then, an encoder encodes the image data in each block differently according to the decision.
摘要:
In an image processor, image data of red, green and blue are converted to image data of lightness and chromaticities, and they are divided into pixel blocks. Then, image data of each block are compressed to data having 4 gradation levels smaller than 256 levels of the image data by generalized block truncation coding. Then, a capacity of image memory can be decreased. An attribute of the image data is decided for each block according to the compressed data. The attribute can be corrected by taking attributes of adjacent blocks into account.
