    摘要: The invention features a system and method to automatically focus an image reader using a single frame of image data. The method comprises exposing sequentially a plurality of rows of pixels in the image sensor. The method further comprising varying in incremental steps the focus of the image reader's optical system from a first setting where a distinct image of objects located at a first distance from the image reader is formed on the image sensor to a second setting where a distinct image of objects located at a second distance from the image reader is formed on the image sensor. As part of the method, the varying of the focus of the optical system occurs during the exposure of the plurality of rows of pixels.

    摘要: A portable data collection device is disclosed. The device includes an imaging assembly including a two dimensional (2D) photosensor array. The imaging assembly is selectively actuatable with a first trigger for reading a target dataform in the imaging assembly's target area and actuatable with a second trigger for capturing a color image of the target object in the target area. The imaging assembly further includes compression circuitry for compressing digital data representative of the target area when the imaging assembly is actuated to capture an image of the target area. The device also includes a viewing assembly to aid an operator in aiming and positioning the device with respect to a target dataform or target object. In one embodiment of the viewing assembly, a liquid crystal display screen is affixed to a pivoting member. When the viewing assembly is actuated an image of the target area is displaced on the display screen. In a second embodiment of the viewing assembly, a manual pivoting member includes an opening. When the pivoting member is positioned a predetermined distance from the operator's eye, a view through the opening corresponds to the imaging assembly's target area.

    摘要: A fixed position dataform reader reads a dataform printed on a substrate and passed through a desired target area. The reader comprises a housing, a first camera assembly, image processing and decoder circuitry, and a mounting support. The housing has a base surface, a face surface, and at least one side surface interconnecting the base surface to the face surface and defining an interior region. The face surface defines an aperture. The first camera assembly includes a two-dimensional photosensor array supported in the interior region and an optics assembly spaced from the two-dimensional photosensor array to focus an image of the dataform onto the two-dimensional photosensor array. The image processing and decoder circuitry is coupled to the camera assembly for generating decoded data representative of the dataform. The mounting support is secured to the housing for mounting the reader in a fixed position with respect to the desired target area.

    摘要: The device includes an imaging assembly including a two dimensional (2D) photosensor array overlied by a RGB color filter. The imaging assembly includes an illumination assembly providing a relatively uniform illumination pattern over an imaging target area. The illumination assembly includes a plurality of sets of surface mount illumination LEDs mounted on a board and a spaced apart lens array for focusing the LEDs on the target area. The lens array includes orthogonal cylindrical optical entry and exit surfaces aligned with each of the illumination LED sets. The optical entry surface defines illumination intensity distribution horizontally while the optical exit surface defines illumination intensity distribution vertically. The board also supports a pair of spaced apart targeting LEDs. The lens array includes aspherical optical entry surfaces and cylindrical optical exit surfaces aligned with each of the targeting LEDs. The cylindrical optical exit surfaces are tipped with respect to their corresponding aspherical optical entry surfaces and are orthognal to each other providing an orgthogonal or "crosshairs" illumination pattern for aiming the imaging assembly at a target.
