Provided are a method and apparatus for encoding and decoding based on intra prediction. The method of encoding based on intra prediction includes predicting a current block by searching for a pre-encoded area in a current picture using pre-encoded pixels adjacent to the current block, and intra prediction encoding the current block so that information indicating that the current block is intra predicted via the predicting of the current block is included. Accordingly, the compression rate of intra prediction encoding is increased even when the current block is not appropriately predicted by using a prediction value obtained from pixels adjacent to the current block.

A fast video encoder (100) and method (500) for selecting (809) Inter macro-block mode or intra macro-block mode is provided. The method can include estimating (502) a rate-distortion cost (801) of a plurality of predictors (203) for coding a video (201), selecting (504) a predictive coding mode for the video based on a minimization of the rate-distortion cost, and coding (505) the image using a predictive mode associated with the minimum rate-distortion cost. The rate-distortion cost can be estimated across Intra macro-block modes and Inter macro-block modes for reducing a computational complexity. Rate-Distortion costs can be terminated early (524) based on statistical information (522) across a plurality of predictors for increasing an encoding speed. A fast estimation of the rate-distortion cost associated with the Intra macro-block mode for making inter / intra macro-block mode decision in a video coding system by exploiting the coding statistics across prediction modes is presented.

An in-camera two-stage compression implementation is described that reduces the latency between snapshots to a fraction of that otherwise required by other systems that either process complete compression following each snapshot or that incorporate heavy, bulky, and expensive RAM hardware capable of maintaining several raw luminosity records (unprocessed file containing a digital image). In the 1st stage compression the raw luminosity record is quickly, yet partially, compressed to available RAM buffer space to allow a user to expeditiously capture a succeeding image. When the higher-priority processes, the user shooting pictures, and stage one compression subside, a 2nd stage compression, which is slower but more effective, decompresses the earlier partially-compressed images, and re-compresses them for saving in flash memory until they are distributed to a remote platform to be finally converted to the JPEG2000 format.

The invention discloses a full-automatic ink-jet printer, and the ink-jet printer comprises a rack, an ink-jet printing mechanism, and a feeding mechanism. The ink-jet printing mechanism and the feeding mechanism are disposed at the upper end of the rack, and the ink-jet printing mechanism is provided with an X-axis guide rail which is arranged in the X-axis direction. The upper end of the X-axis guide rail is provided with a Y-axis guide rail which is arranged in the Y-axis direction, and the upper end of the Y-axis guide rail is provided with a Z-axis guide rail which is arranged in the Z-axis direction, wherein the upper end of the Z-axis guide rail is provided with an ink-jet printing device. The feeding mechanism is provided with a feeding guide rail which is arranged in the Y-axis direction. The feeding guide rail is disposed on a guide rail adjustment device which is arranged in the X-axis direction and is fixed on the rack. The ink-jet printer is novel in design, is simple in structure, achieves safe, accurate, quick and all-around spraying on a PCB, can randomly adjust the shape and size of a character, can carry out spraying in a shape like a Chinese character Mi, can achieve on-line testing, and irons out defects in various conventional technologies of manual spraying.
