摘要： An analyzer estimates the time for rendering image data based on the number, types, etc., of rendering commands, stored in an intermediate memory, and determines whether or not there is a possibility of overrun. If there is the possibility of overrun, image data of respective bands formed in a band buffer are sequentially compressed and stored into a compressed image memory. When the image data for one page has been stored, the data in the compressed image memory is sequentially expanded and supplied to a printer engine. This avoids failure of image output due to overrun, while reducing the capacity of the image memory.
摘要翻译：分析器基于存储在中间存储器中的渲染命令的数量，类型等来估计渲染图像数据的时间，并且确定是否存在超限的可能性。如果存在超限的可能性，则形成在频带缓冲器中的各个频带的图像数据被顺序压缩并存储到压缩图像存储器中。当存储一页的图像数据时，压缩图像存储器中的数据被顺序地扩展并提供给打印机引擎。这样可以避免图像输出由于超限而导致的故障，同时降低了图像存储器的容量。

摘要： The present invention allows an image to be coded within a target size without necessitating the image to be input again during the coding of the image, with a mode reflecting a user's intention for coding. To solve this problem, input image data is coded at coding unit 102 and stored into first and second memories, respectively. Coding sequence unit 108 monitors the quantity of codes. When a set value is determined to be reached, coding sequence unit 108 makes data in first memory to be discarded and directs coding means to further increase a quantization step, and continues coding. As previous coded data is stored in second memory, the data is re-coded with the same quantization step as that of coding unit 102 after changing of a parameter at re-coding unit 109, and the re-coded data is stored into first and second memory. At this moment, coding unit 102 and re-coding unit 109 perform an operation and coding on quantization error according to a mode of quantization operation designated at mode designation unit 125.

摘要： An image input through an input unit is compressed by an encoding unit and stored in first and second memories. A first counter counts the data in its code amount. When the amount of encoded data generated reaches a predetermined size, an encoding sequence control unit sets quantization steps in the encoding unit and re-encoding unit to increase compression ratios. The encoding sequence control unit clears the first memory, causes the re-encoding unit to re-encode the encoded data stored in the second memory, and stores the resultant data in the first memory. Since the encoding unit continues encoding data with the set quantization step, the encoded data are stored in the first memory from the start of the image. Subsequently, every time the data amount stored in the first memory reaches a predetermined amount, the quantization step is increased, and the processing is repeated.

摘要： From inputted multilevel image data it is generated, for each pixel, image area information constituted by an image area component indicating whether the pixel exists in a character•line drawing area or halftone area and an image area component indicating whether the pixel is chromatic or achromatic. The information is encoded by a lossless encoding unit on a block basis and stored, and an amount of code is monitored. When the amount of code exceeds a target amount, the lossless encoding unit performs encoding upon changing image area components, of subsequently input image area components, which coincide with a condition. The codes that have already been stored are temporarily decoded by a lossless code re-encoding unit, and the above image area components are changed. The resultant data is then re-encoded and stored.

摘要： This invention provides a lossless 4-point Hadamard transform circuit which can minimize the number of times of addition/subtraction calculations, and reduce the number of times of round processing required to convert data including a fractional part into an integer. To this end, a DC coefficient generating unit summates four input data, and shifts the summation result 1 bit to the right to halve the summation result and to round the halved result by truncating a fractional part of the result. This 1-bit shift right result is output as a DC coefficient. An intermediate data generating unit generates, as intermediate value, a difference value between one input data of the four input data and the DC coefficient obtained by the DC coefficient generating unit. An AC coefficient generating unit generates three AC coefficients by adding the intermediate data generated by the intermediate data generating unit to other three input data.

摘要： This invention allows Huffman encoding using a common Huffman table according to basic quantization values Qi,j even when image data expressed by n bits falling within the range from L to K is JPEG-coded, and can suppress the Huffman table size from increasing. To this end, a basic quantization table storage unit stores quantization step values Q0,0 to Q7,7 used in baseline JPEG coding. A minimum quantization step generator outputs a minimum quantization step value Qn—min to a comparator/selector according to the number n of bits of each color component of image data to be coded. The comparator/selector compares the quantization step values Q0,0 to Q7,7 with Qn—min and selects larger ones, and outputs the comparison results to a quantizer as Q′i,j. The quantizer stores Q′i,j in a quantization table storage unit and quantizes orthogonal transformation coefficients output from a DCT transformer.

摘要： A bumper is provided with to-be-engaged projections, a radiator grille is provided with engaging projections. The radiator grille is allowed to move and approach bumper rearward of a vehicle. According to this configuration, the engaging projections engage the to-be-engaged projections and they are engaged with and fixed to each other. At this time, a bumper-side seizing unit of the bumper is fitted into a grille-side seizing unit of the radiator grille, thereby limiting the vertical direction. In an engaged state between the engaging projections and the to-be-engaged projections, an inclining surface of one of the engaging projections comes into contact with a rearward inclining surface of the one of the to-be-engaged projections, and an inclining surface of the other engaging projection is separated from a rearward inclining surface of the other to-be-engaged projection.
