    摘要： A multi-dimensional imaging device and method for automated exposure control that implement two distinct modules to control the exposure and gain settings in the imager so that processing can occur in a multi-tasking single CPU environment. The first module, referred to herein as the imager control module, controls the exposure and gain settings in the imager. The first module is typically implemented in a high priority routine, such as an interrupt service routine, to insure that module is executed on every captured frame. The second module, referred to herein as the histogram processing module, calculates a target contrast (the product of the targeted exposure and gain settings) based on feedback data from the first module and image data from memory. The second module is typically implemented in a low priority routine, such as a task level routine, to allow for the routine to be executed systematically in accordance with priority.

    摘要： There is described an indicia reading terminal that can be operative to process a frame of image data for attempting to decode a decodable indicia. A frame can be a frame that is among a succession of frames for subjecting to processing subsequent to and during a time a trigger signal is active. Such a succession of frames can include zero or more binned frames, zero or more unbinned frames, zero or more windowed frames, and zero or more unwindowed full frames. An indicia reading terminal can also include a variable focus imaging lens.

    摘要： There is described in one embodiment an imaging apparatus having an image sensor, and a plurality of operating states. Operation of the imaging apparatus can be differentiated between the operating states. In one operating state, the imaging apparatus can capture a frame of image data having image data corresponding to a predetermined number of pixels of the image sensor. The operating states of the imaging apparatus can be user selectable. There is described in one embodiment an apparatus having an image sensor operative to capture a relatively smaller sized frame, wherein a characteristic of light directed by an illumination assembly for capture of a relatively larger sized frame is determined utilizing the relatively smaller sized frame.

    摘要： A method for decoding a decodable symbol using an optical reader having a 2D image sensor that is configured to operate in a partial frame capture operating mode. In a partial frame operating mode, the reader clocks out and captures at least one partial frame of image data having image data corresponding to less than all of the pixels of an image sensor pixel array. In one embodiment, the reader operating in a partial frame operating mode captures image data corresponding to a linear pattern of pixels of the image sensor, reads the image data, and attempts to decode for a decodable bar code symbol which may be represented in the image data.

An indicia reading terminal can also include a variable focus imaging lens. Control of the variable focus imaging lens can be provided so that during an exposure period for a binned frame the variable focus imaging lens is set to a short range focus setting and further so that during an exposure period for a windowed frame the variable focus imaging lens is set to a long range focus setting.
