摘要： An operator is guided to move an imaging reader to an optimum reading position in which to read a symbol by image capture. Optimum image capture occurs substantially at an imaging plane of an imaging assembly, and the operator is visually guided so that the symbol is located substantially at the imaging plane in a working range of distances.

摘要： An imaging-based bar code reader that includes an item guide to guide movement of an item including a target bar code such that target bar code passes through a field of view of the reader in a straight line. The reader further includes an imaging and decoding system to: 1) capture a series of images which include at least a part of the target bar code as the bar code is moved through the field of view of the reader; 2) sequentially analyze the series of captured images, for each captured image, identifying areas of the captured image representative of an image of the target bar code and decode decodable portions of the imaged target bar code; and 3) combining the decoded portions of the imaged target bar code using a sequence stitching method to obtain a full decode of the target bar code.

摘要： An imaging lens assembly captures return light through a window of a vertical slot scanner from a target located in a range of working distances along an optical axis away from the window, and projects the captured return light onto an array of a solid-state imager. The imaging lens assembly is optically modified for non-uniform magnification within, and for increasing resolution at an outer peripheral region of, a field of view of the array, in an imaging plane generally perpendicular to the optical axis. The magnification is at least partly increased in the imaging plane with increasing radial distance away from the optical axis, to enable reading of the target when tilted relative to the optical axis and located at the outer peripheral region of the field of view.
