摘要： A system and method utilizing the principles of axial chromatic aberration for auto-focusing an image onto an image sensor are provided. The system and method are particularly suitable for incorporation within an optical code reader. A signal processor analyzes data signals representative of the intensity or magnitude of wavelength components of an impinged image onto the image sensor for determining a value indicative of the focus quality of the impinged image. An actuator controls movement of a lens in accordance with the determination until obtainment of a desired focus quality. A decoder decodes the image having the desired focus quality.

摘要： A miniature imager for reading target images. The optical and electrical systems of the miniature imager are optimized to reduce one or more dimensions or the volume of the imager. In accordance with one embodiment the pixel pitch and focal length are decreased for that of a larger imager to maintain a comparable field of view for each pixel. The decreased pixel pitch allows the area of the aperture and the instantaneous field of view of the pixel to remain constant while decreasing the overall size of the imager. In other embodiments apparatus and techniques reduce and/or eliminate the need for illumination of a target by the imager thereby reducing the overall power consumed by the imager and/or its overall size. The imager has an increased working range.

摘要： Interleaving multiple logical data streams into one physical data stream reduces overhead required to process the multiple logical data streams. Multiple arrays of data values are interleaved into a combined array of data that simulates a frame of data for input to a data port such as a video port. Revised timing and synchronization signals are provided to permit transmission of the combined array according to video data port protocol. The processor includes instructions for locating the various arrays of data values within the combined array.
