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.

An iris imaging system used for biometric identification provides a combined iris imager and wavefront sensor. The detector array allows for independent readout of different regions, such that a wavefront sensor region can be read out fast while allowing signal to integrate on the iris imaging region. Alternatively, the entire array may be used for wavefront sensing during an acquisition phase, and then at least a portion of the array may be switched to be used for iris imaging during a subsequent imaging phase. An optical periscope optionally allows various optics to be inserted in front of the combined iris imager and wavefront sensor. In another embodiment, the glint image of an on-axis or near on-axis illumination source is picked off at the image plane and directed to the wavefront sensor optics, while allowing all of the light from the iris field to pass through to the iris imaging camera.

An extra-oral digital panoramic dental x-ray imaging system is disclosed for multi-layer panoramic and transverse X-ray imaging. The system includes an X-ray source and a digital imaging device capable of “real time” frame mode output. The source and imaging device are mounted in a mechanical manipulator defining the trajectory of a predetermined image layer. The imaging device communicates with a processor that generates a frames memory from which an image reconstruction mechanism composes the final images. For “real time” imaging, the frames memory is a fast data storage system such as RAM. The processing unit executes the reconstruction algorithms, allowing the system to selectively generate dental panoramic X-ray images, dental transverse x-ray images and dental tomosynthetic 3D images.

An optical reader for reading encoded microparticles. Each microparticle has an elongated body with an optically detectable code that extends along a longitudinal axis of the corresponding elongated body. The reader includes a plate that has a plurality of channels. The channels are configured to receive and align the microparticles so that the codes of the microparticles are in a common fixed orientation relative to each other. The reader also includes an illumination source for illuminating the microparticles on the plate. The codes in the microparticles reflect a portion of incident light and permit a portion of the incident light to pass through the microparticles thereby providing an output signal indicative of the code. The reader also includes a detection device that is configured to capture the output signal provided by the microparticles.

A preferred method for transmission electron microscopy includes a step of generating a microscopy signal. The microscopy signal is then detected with an active pixel detector that includes a plurality of pixels. Each of the pixels includes at least one photodiode. Each pixel integrates an incident signal over a collection time period. Using a massively parallel on chip analog to digital conversion, very fast read out times can be achieved, e.g., many frames per second. In a preferred embodiment, the read out time permits there to be a single electron event recorded per pixel, indicating either a single electron or the lack thereof. This permits simple accumulation of the pixel counts for each pixel in read-out and storage electronics.

A convolution interleaver for processing a codeword which is derived from an input block of symbols using a redundancy-adding code (22) and which has more symbols than the input block, where the codeword has a sequence of interleaving units, each interleaving unit having at least two symbols, comprises an interleaving device (10). The interleaving device alters the sequence of interleaving units in order to obtain an interleaved codeword which has an altered sequence of interleaving units. In particular, the interleaving device does not alter the order of the symbols within an interleaving unit. However, the order of the interleaving units in the codeword is altered among one another or in respect of a preceding or succeeding codeword.

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.
