An electronic image stabilizer in a digital camera compensates for camera motion-induced blurriness by segmenting exposure times into multiple shorter exposure times and summing the individual pixels from successive frames after applying an appropriate motion correction. Motion is detected by computing the correlation function between successive images, and compensation is applied by maximizing the correlation function. This avoids the need for mechanical stabilization devices in order to detect or correct the motion as is done in prior art. This method further enables the detection of moving objects in a still background, and correction of blurriness images due to such motion.

In a memory readout circuit for use in a phase-change memory device comprising phase-change elements as memory cells, a sense amplifier sets readout voltage, which is applied to a selected phase-change element selected among the phase-change elements by a column selecting switch, to voltage equal to or higher than hold voltage of the selected phase-change element but lower than transition voltage of the selected phase-change element in a readout cycle. The selected phase-change element is read out as a dynamic state in the case where the selected phase-change element is in a set state.

The invention discloses a data processing method of a next-generation sequencing (NGS) data analysis platform (IMP). The next-generation sequencing data analysis platform implements an entire next-generation sequencing processing process as a single step from inputting of short-reading long-sequences of an FASTQ file format to outputting of mutation detection of a standard VCF file format; at thesame time, the method also provides an option of outputting an intermediate result of sequence alignment in a standard SAM or BAM format; longer data searching and loading time required for I/O accessing of hard drives and SSDs can be avoided through massive memory accessing without using slow I/O to exchange data; hash table writing or reading, deletion of duplicated alignment records and mutation detection are all enabled to be faster; quick next-generation sequencing data analysis can be realized on the premise of not impacting analysis quality; and compared with speeds of existing schemes,a speed of the method is increased up to 20 times.

An image-processing apparatus includes an input unit for inputting operational signals. The input unit includes an operation surface and outputs, as the operational signals, a position detection signal representing a detected operation position of an operation instrument moving on the operation surface and a selection confirmation signal generated when a selection operation is confirmed on the operation position. The image-processing apparatus further includes a display unit and a display-controlling unit for controlling the display state of the display unit based on the operational signals. The display-controlling unit highlights an index corresponding to the operation position when the position detection signal is output in a state in which indices to be selected are displayed on the display unit, and reads and displays main data corresponding to the highlighted index when the selection confirmation signal is output.

A waveform reproduction apparatus and process for carrying out waveform reproduction without delays. Waveform data expressing first and latter half portions of a musical tone waveform are stored on a storage device. In response to a tone generation start indicator, waveform data that express first half portions corresponding to the tone generation start indicator are successively read out and corresponding musical tone waveforms are formed. Following this, the waveform data that express latter half portions corresponding to the tone generation start indicator are successively read out and corresponding musical tone waveforms are formed. After the first half portions are successively read out and corresponding musical tone waveforms are formed, if the read-out of the waveform data that express the latter half portions corresponding to the tone generation start indicator is not completed in time, the formation of the musical tone waveforms is based on a specified segment set in the first half portion of the waveform data.
