摘要： Image data representing a desktop image for a client device that is accessing the desktop remotely is compressed according to a method that preserves image fidelity in selected non-text regions. The method, which is carried out in a remote server, includes the steps of generating image data for the remote desktop image and analyzing different regions of the remote desktop image, identifying those regions of the remote desktop image that are text regions, selecting non-text regions of the remote desktop image for lossless compression based on a spatial relationship between the non-text regions and the text regions, compressing the image data using a lossless compression protocol for a portion of the image data corresponding to the selected non-text regions, and transmitting the compressed image data to the client device.

摘要： In an image processing apparatus for encoding image data and a method of controlling the same, whether an attribute of each of a plurality of areas in image data corresponds to an edge in an image based on the image data is determined, and one of a plurality of sub-sampling processes is selected according to the determination for each of the plurality of areas. Note that the plurality of sub-sampling processes can sub-sample color difference components of each of the plurality of areas by different processes. By the sub-sampling process selected as that corresponding to each of the plurality of areas, each of the plurality of areas is sub-sampled to encode the image data.

摘要： Color image data composed of pixels arranged in a matrix wherein colors are expressed in bit rows is created from an acquired document file, and same-resolution binary image data and low-resolution binary image data composed of binary pixels arranged in a matrix are created based on the color image data. A first combining process is performed in which a lower bit value of a predetermined color of the pixels of the color image data is replaced with the value of the corresponding ones of the pixels of the same pixels, and a second combining process is performed in which a lower bit value of a color other than the bit replaced in the first combining process in the pixels of the first combined image data is replaced with the value of the corresponding ones of the pixels of the low-resolution binary image data.

摘要： A data compressing method which can efficiently compress image data containing color data is provided. A compressed data expanding method which can expand the compressed data at high speed is provided. Image data containing color data are compressed into image data including: address fields code A, code B, code C which hold addresses of color RAMs storing color information corresponding to the color data; classification fields which, when the color RAMs are classified into prescribed categories A, B, C, hold classification information of the categories including the color data; and run length fields RL which hold numbers of successive repetitions of color data. To expand the compressed image data, the classification fields are decoded to determine the categories in which the color data are included. Based on the determined categories, the first processing for decoding the address fields to generate addresses, and the second processing for supplying the generated addresses by the numbers of successively repeated color data in the run length fields to access the color RAMs are performed.

摘要： The present invention provides a method for compressing image data. The method first detects a pattern in a first subset of the image data, where the second subset being collocated to a second subset. If no pattern is detected, then a text mode context model is selected. If a pattern is detected, then the period of the pattern is detected and a pattern mode context model is selected. The pattern mode context model has a width directly related to the period of the pattern detected. An arithmetic compressor compresses the second subset using the selected context model.
