摘要： A block decoding method and system capable of decoding and outputting data in a rotated direction, which has a Huffman decoding device, a zigzag device, an inverse quantizer, an inverse discrete cosine device, a data buffer and a controller. In this invention, a dynamically set decoding window is introduced to perform the complete JPEG decoding on blocks in the decoding window and the Huffman decoding on blocks out of the decoding window. When decoding and outputting one or more columns of blocks in the decoding window is complete, the decoding window is dynamically adjusted to a next location for decoding and obtaining a next column of block or a next plurality of columns of blocks.

摘要： A compound inkjet print head printer has a compound print head module. The compound print head module includes at least two inkjet print heads for providing ink droplets of one color but with different sizes. Since the compound inkjet print head module provides different sizes of ink droplets in a swath, the number of print swaths can be decreased. The compound inkjet print head printer increases a printing speed with high photo quality.

摘要： A method creates printing data applied to a printer that is capable of generating different sizes of ink drops. Firstly, a halftoning threshold table is created based on all possible combinations that are determined based on the quantity of the printheads and the sizes of ink drops quantity provided by each printhead. When the image data to be printed is received, each pixel of an image will correspond to one combination based on the halftoning threshold table. The corresponding combination is deemed as a halftoning encoded data and represented by several bits. These bits can be separated into plural groups, where the bits contained in each group are for driving a specific printhead. That is to say, each printhead has its own driving data so that the printing process will have superior efficiency.
