摘要： An image processing apparatus compresses multi-level images created by a computer or the like at a high compression rate. To achieve this, the image processing apparatus includes an ADCT compression unit for compressing input multilevel image data for every block of data (the blocks having a predetermined size) by an irreversible compression method, and a reversible compression unit for compressing the input multilevel image data for every block by a reversible compression method. Selection between output data from the two compression units on the basis of data having a predetermined level and compressed by the reversible compression unit.

摘要： When image data is compressed in units of blocks, if a compressed data amount D obtained by reversibly compressing a block, and a predetermined value L satisfy D.ltoreq.L, the block is reversibly compressed; if they satisfy D>L, the block is irreversibly compressed, so that computer-created image data is compressed while preventing deterioration of image quality, and a gradation image or a natural image is efficiently compressed. When a pixel of interest has the same value as color data (C.sub.1) of the immediately preceding pixel, the shortest code `1` is output; when the pixel of interest has the same value as color data (C.sub.2) of a pixel, which has color data different from C.sub.1, and appears latest, the second shortest code `01` is output; when the pixel of interest has the same value as color data (C.sub.3) of a pixel, which has color data different from C.sub.1 and C.sub.2, and appears latest, the third shortest code `001` is output; when the pixel of interest has color data different from C.sub.1, C.sub.2, and C.sub.3, an unused code `000` is output, and the color data at that time is output. Thus, a computer-created image is compressed at a high compression ratio without causing deterioration of image quality.
摘要翻译：当以块为单位压缩图像数据时，如果通过可逆地压缩块获得的压缩数据量D和预定值L满足D L，则块被不可逆地压缩，使得计算机创建的图像数据被压缩，同时防止图像质量的劣化，并且灰度图像或自然图像被有效地压缩。当感兴趣的像素具有与前一像素的颜色数据（C1）相同的值时，输出最短代码'1' 当感兴趣的像素具有与颜色数据不同于C1的像素的颜色数据（C2）相同的值并且出现最新时，输出第二最短代码'01' 当感兴趣的像素具有与具有与C1和C2不同的颜色数据的像素的颜色数据（C3）相同的值并且出现最新时，输出第三最短代码'001' 当感兴趣的像素具有不同于C1，C2和C3的颜色数据时，输出未使用的代码'000'，并且输出那时的颜色数据。因此，以高压缩率压缩计算机创建的图像，而不会导致图像质量的劣化。

摘要： An image processing apparatus initially stores variable length codes corresponding to a significant frequency component, and variable length codes corresponding to a less significant frequency component If while storing the variable length codes into the storage means, it is detected that the storage means is full (with variable length codes), the control means makes room for the storage of further variable length codes corresponding to the more significant frequency component by canceling variable length codes stored in the storage means which correspond to the frequency component.

摘要： A first comparator compares pixel data outputted by a pixel-data generating unit with an immediately preceding item of pixel data that has been latched by a first latch. The result of comparison is delivered to a first memory unit. If the result of comparison is that the two compared items of pixel data do not agree, a second comparator compares the pixel data outputted by the pixel-data generating unit with pixel data latched by a second latch. The result of this comparison is delivered to a second memory unit. If the result of the comparison performed by the second comparator is that the two compared items of pixel data do not agree, the pixel data from the generating unit is stored in a third memory unit. When the pixel data latched by the first latch does not agree with this pixel data, the content latched by the second latch is updated to the content latched by the first latch and the content latched by the first latch is updated to this pixel data.
