摘要： This invention implements a fast lossless transform almost free from a delay with a small calculation amount. The lossless transform can be used to perform lossless coding and lossy coding quickly. A first calculation unit multiplies data D0, D1, D2, and D3 input to the input terminals by respective weighting coefficients {a0, a1, a2, a3} of {½, −½, −½, −½}, and summates the products. A rounding unit in the first calculation unit rounds the sum into an integer and outputs the integer value E. A second calculation unit multiplies the value E by weighting coefficients {b0, b1, b2, b3} of {−1, 1, 1, 1} set for the respective input data, and adds the products to the respective input data. This invention sets, for the relationship between the first and second weighting coefficients, a condition that a0*b0+a1*b1+a2*b2+a3*b3=−2 or 0.

摘要： This invention improves the arithmetic precision even for image data in which each component of one pixel is expressed by 8 bits by fully utilizing the 12-bit data processing performance of an Extended sequential DCT-based JPEG decoding/encoding apparatus, so that image deterioration due to JPEG compression which is observed in an image portion where the gray levels change slowly, i.e., a pseudo edge can be hardly generated, thus improving the image quality. To this end, a header interpreter interprets the header of encoded data to be decoded to determine if the encoded data is that of 8-bit image data per component or that of 12-bit image data per component, and outputs the result to a bit shift unit, rounding processor, and inverse quantizer. Upon reception of a message indicating that the encoded data is that of 8-bit color image data per component, the bit shift unit stores a result obtained by shifting a quantization step of a quantization table stored in the header by 4 bits in the MSB direction in a quantization table storage unit. The inverse quantizer multiplies a decoded value decoded by a Huffman decoder by the quantization step stored in the quantization table storage unit to generate 12-bit DCT coefficients. The DCT coefficients are processed by an IDCT unit to obtain image data, and the image data is rounded to 8 bits again, thus outputting image data as a decoded result.
摘要翻译：本发明通过充分利用基于扩展顺序DCT的JPEG解码/编码装置的12位数据处理性能，即使对于一个像素的每个分量由8位表示的图像数据也提高了算术精度，使得图像劣化到在灰度级变化缓慢的图像部分中观察到的JPEG压缩，即，几乎不能产生伪边缘，从而提高图像质量。为此，报头解释器解释要解码的编码数据的标题，以确定编码数据是每个分量的8位图像数据还是每个分量的12位图像数据的编码数据，并将结果输出到位移位单元，舍入处理器和逆量化器。在接收到指示编码数据是每个分量的8位彩色图像数据的消息的消息时，位移单元将通过将存储在报头中的量化表的量化步长移位4位的结果而获得的结果在MSB方向在量化表存储单元中。逆量化器将由霍夫曼解码器解码的解码值乘以存储在量化表存储单元中的量化步长，生成12位DCT系数。 DCT系数由IDCT单元处理以获得图像数据，并且图像数据再次舍入为8位，从而输出图像数据作为解码结果。

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.
