| 20080296393 | MULTIPURPOSE OPTICAL READER - An optical reading device for collecting and processing symbology data comprising: an image sensor array of pixels for converting light reflected from a target containing a machine readable indicia into output signals representative thereof, the image sensor being operated in a global shutter mode wherein all or substantially all of the pixels in the array are exposed simultaneously during an exposure time; receive optics for directing light from the target to the image sensor array, the optics having a receive optics optical axis; a processor for decoding the output signals; an illumination source for generating illumination light illuminating the target and illumination optics for directing the illumination light onto the target; a housing encapsulating the image sensor array, receive optics and illumination source; wherein the processor decodes in a first mode to continuously process available output signals automatically and a second mode to output signal in response to an activation event. | 12-04-2008 |
| 20090026267 | INDICIA READING TERMINAL PROCESSING PLURALITY OF FRAMES OF IMAGE DATA RESPONSIVELY TO TRIGGER SIGNAL ACTIVATION - There is described a decodable indicia reading terminal which in one embodiment can capture and process a certain (e.g., a first) and a subsequent (e.g., a second) frame of image data, wherein the certain and the subsequent frames have different imaging attributes. In one embodiment the attributes between certain and subsequent frames are differentiated in that the certain frame represents light incident on pixels of a first image sensor and the subsequent frame of image data represents light incident on pixels of a second image sensor spaced apart from the first image sensor. Additionally, or in the alternative, the attributes between certain and subsequent frames can be differentiated in that the first frame represents light incident on an image sensor under a first illumination profile and the subsequent frame represents light incident on pixels of an image sensor under a second illumination profile. In one embodiment imaging attributes of a frame subject to decoding are maintained constant for each frame subject to processing during a time that a trigger signal remains active. In one embodiment the certain and subsequent frames can be processed to yield partial decoding results and the partial decoding results can be combined to form a complete decoding result. | 01-29-2009 |
| 20100147956 | INDICIA READING TERMINAL INCLUDING FRAME PROCESSING - 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. 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. | 06-17-2010 |
| 20110036910 | INDICIA READING TERMINAL OPERATIVE FOR PROCESSING OF FRAMES HAVING PLURALITY OF FRAME FEATURIZATIONS - The present invention relates to an indicia reading terminal operative to capture and process a succession of frames of image data during an operator activated read attempt. The succession of frames can comprise alternating frames, wherein the alternating frames can have first and second frame featurizations. The frames having the first frame featurization can have a first window position and the frames of the second featurization can have a second window position. In one embodiment, exposure of frames of the first featurization can be controlled according to a first exposure control process and exposure of frames of the second featurization can be controlled according to a second exposure control process. In one embodiment, gain that is applied to image signals of frames of the first featurization can be controlled according to a first gain control process and gain that is applied to image signals of frames of the second featurization can be controlled according to second gain control process. | 02-17-2011 |
| 20110038563 | INDICIA READING TERMINAL HAVING MULTIPLE EXPOSURE PERIODS AND METHODS FOR SAME - There is described an image reading terminal having an image sensor array including a plurality of pixels, a first optical assembly for focusing imaging light rays onto a first set of pixels of an image sensor array and a second optical assembly for focusing imaging light rays onto a second set of pixels of the image sensor array. The first set of pixels and the second set of pixels of the image sensor array can have different exposure settings in a single exposure period for the image sensor array. In one embodiment, the indicia reading terminal can be adapted to process image data corresponding to pixels of the image sensor array for attempting to decode a decodable indicia. | 02-17-2011 |
| 20110089245 | INDICIA READING TERMINAL INCLUDING FOCUS ELEMENT WITH EXPANDED RANGE OF FOCUS DISTANCES - Embodiments of the present invention comprise an indicia reading terminal including a focus element that extends the range of focus distances at which the indicia reading terminal can decode decodable indicia. In one embodiment, the focus element comprises a variable form element and a variable position element, the combination of which causes an image distance that can change in accordance with a separation distance between these two elements. The focus element can comprise an actuator, e.g., a piezoelectric actuator, which can be coupled to the variable position element in a manner that can cause the variable position element to deform the variable form element, and in one example, the deformation changes the focal length of the variable form element. | 04-21-2011 |
| 20110101102 | OPTICAL READING DEVICE WITH PROGRAMMABLE LED CONTROL - An apparatus comprising: a sensor array having rows of pixels which are exposed to symbol indicia, wherein the sensor array generates a sync signal; an aiming pattern generator for producing an aiming pattern superimposed on the symbol indicia; a processor which utilizes the sync signal to control the aiming pattern generator to: turn on the aiming pattern during exposure of a first predetermined row of pixels; turn off the aiming pattern during exposure of a second predetermined row of pixels; turn on the aiming pattern during exposure of a third predetermined row of pixels; and, a housing for housing the sensor array, aiming pattern generator and processor for hand held operation. | 05-05-2011 |
