    摘要： An optical code reader is provided including imaging circuitry having an array of photo sensing devices capable of sensing light incident on the array and outputting a plurality of pixel signals corresponding to the sensed light. The reader further includes control and logic circuitry for receiving a subset of the plurality of pixel signals, processing the received subset of the plurality of pixel signals for determining if the received pixel signals meet at least one predetermined condition, and outputting a selection control signal in accordance with the processing results. A focus analysis software module executable by the control and logic circuitry determines the focus quality of the received pixel signals. A selector control software module executable by the control and logic circuitry generates a selection control signal in accordance with the determined focus quality of the received pixel signals. Selector circuitry selectively enables the imaging circuitry to output selected pixel signals of the plurality of pixel signals in accordance with the selection control signal.

    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： An imaging and illuminating engine for an optical code reader to illuminate and image remote target indicia, such as an optical code, is provided. The engine includes an image sensor for receiving reflected illumination from the remote indicia and an illumination assembly for providing illumination of the remote indicia. The illumination assembly is capable of providing a plurality of different outputs, such as light having different wavelengths. The illumination assembly can also be provided with a single illuminating device for providing one illumination output for illuminating substantially the entire field of view. A transmissive, optical element overlays the engine for preventing light generated by the illumination assembly from reflecting back towards the image sensor. The imaging engine is an integrated circuit package configured for easily interfacing within an optical code reader as a plug-and-play component.

    摘要： An imaging and an illuminating engine is provided for an optical code reader to image and illuminate remote target indicia. The engine includes an image sensor for receiving reflected illumination from the remote indicia and at least two illumination assemblies for providing illumination of the remote indicia. Each illumination assembly is capable of providing a number of different outputs, such as light having different wavelengths or different output durations. A transmissive, optical element overlays the engine for preventing light generated by the at least two illumination assemblies from reflecting back towards the image sensor. The imaging engine is an integrated circuit package for easily inserted and interfacing within an optical code reader as a plug-and-play component.
