Bar code reading device with global electronic shutter control
ActiveUS7568628B2Minimize degradationTelevision system detailsTransmission systemsSensor arrayElectronic shutter
The invention features an image reader and a corresponding method for capturing a sharp distortion free image of a target, such as a one or two-dimensional bar code. In one embodiment, the image reader comprises a two-dimensional CMOS based image sensor array, a timing module, an illumination module, and a control module. The time during which the target is illuminated is referred to as the illumination period. The capture of the image by the image sensor array is driven by the timing module that, in one embodiment, is able to simultaneously expose substantially all of the pixels in the array. The time during which the pixels are collectively activated to photo-convert incident light into charge defines the exposure period for the sensor array. In one embodiment, at least a portion of the exposure period occurs during the illumination period.

Automatic focusing system for imaging-based bar code reader
An automatic focusing system for an imaging-based bar code reader. The automatic focusing system employs a two step process for moving a lens of an imaging system along its path of travel such that a sharp image of a target bar code is projected or focused onto an imaging system pixel array. The first step is laser ranging which utilizes a laser beam for range finding. Laser ranging determines a distance between the imaging system pixel array and the target bar code. Given the determined distance, the automatic focusing system moves the lens to a suitable position for imaging the target bar code. If ambient conditions prevent laser ranging from properly working, the second step is focus analysis. Focus analysis involves moving the lens in accordance with a search routine and analyzing image frames of the target object to find a suitable focus position.

The present invention is an imaging device which can be equipped with decode functionality and which can be configured to operate in at least one of four user selected modes. In a first, “message only” mode, the device stores into a designated memory location a decoded-out message corresponding to a decodable indicia. In a second, “image only” mode, the device stores into a designated frame storage memory location an image representation of a scene. In a third, “omage plu message” mode the device stores into a designated frame storage memory location an image representation comprising a representation of a decodable symbol and into the same or other memory location the decoded-out message decoded from the decodable indicia, or data corresponding to the same. In the fourth, “two-step message and image” mode, the device is controlled to capture an image a first time for decoding a decodable indicia and a second time for capturing an image that is associated with the decoded-out message corresponding to the decodable indicia.

An imaging system (FIG. 3) is disclosed that has a wavelength dependent focal shift caused by longitudinal chromatic aberration in a lens assembly (203) that provides extended depth of field imaging due to focal shift (213,214) and increased resolution due to reduced lens system magnification. In use, multiple wavelengths of quasi-monochromatic illumination, from different wavelength LEDs (206,207) or the like, illuminate the target, either sequentially, or in parallel in conjunction with an imager (200) with wavelength selective (colored) filters. Images are captured with different wavelengths of illumination that have different focus positions (208,209), either sequentially or by processing the color planes of a color imager separately. Extended depth of field, plus high resolution are achieved. Additionally, information about the range to the target can be determined by analyzing the degree of focus of the various colored images.

An optical scanner is capable of effectively correcting a difference with respect to the sub-scanning direction between the positions of optical spots for scanning photoconductor drums of a tandem type color image forming apparatus. The optical scanner includes an optical axis adjusting part. The optical axis adjusting part uses a deflecting mirror or a wedge-shaped prism to deflect the optical axis of an optical beam with respect to the sub-scanning direction. As a result, it is possible to accurately correct a resist difference among individual image forming stations and form a high-quality color image without any color displacement.
