  • Publication number: 20140351485
    Abstract: An approach is described to overcome the rapid consumption of available flash space when frequently modifying files stored on the flash space. This “differential” sector approach determines the correlation between the new content and the old content, and saves only the “delta” part of the old and the new content to the sectorized memory device. A predetermined threshold can be used to determine whether to use the “differential” sector approach or the fixed sector approach, based on the amount of data change in a given memory access request.

  • Patent number: 8794520
    Abstract: A method for operating an indicia reading terminal is provided wherein image information can be processed for determining a location of a decodable indicia representation for a certain frame of image data, the result of the processing can be utilized for determination of an imaging parameter, the imaging parameter can be utilized for capture of a subsequent frame and the subsequent frame can be subject to image processing.

  • Publication number: 20130021507
    Abstract: Image processors and methods of processing image data from monochrome and color sensors, for example, pixels, are provided. The exposure time of the monochrome pixels is limited and the exposure time of the color pixels is extended to enhance image quality while limiting the “cross talk” that can interfere with prior art methods and devices. The monochrome and color sensors may be provided in two-dimensional image sensor arrays which can be provided in optical readers, for example, portable hand-held optical readers. Aspects of the invention can be applied to visual imaging, for example, in bar code or image handling applications, and to the detection and processing of any form of electromagnetic radiation.

  • Publication number: 20100316291
    Abstract: There is described in one embodiment an indicia reading terminal having an image sensor pixel array incorporated therein, wherein the terminal is operative for decoding of decodable indicia and for providing color frames of image data for storage or transmission. An imaging terminal in one embodiment can include an image sensor having a hybrid monochrome and color image sensor pixel array including a first subset of monochrome pixels and a second subset of color pixels. Embodiments of data compression circuits and/or methods for processing image data from the hybrid image sensor pixel array are provided.
