Techniques for characterizing an optical system (for example, a printer verifier) are provided. In this regard, the optical system may be characterized for scanning a printed image. The characterization of the optical system includes determining an effective aperture size of the optical system, and correspondingly an effective resolution at which the optical system can be configured to scan a portion of the printed image according to verification requirements.

Disclosed herein is a barcode reading system that includes an image decoding system, a communication interface, and an image sensor system package. The image decoding system may include a processor, memory, and a decoder stored in the memory. The image sensor system package may be coupled to the image decoding system via the communication interface. The image sensor system package may include a photo sensor array and pre-processing circuitry. The photo sensor array may be configured to capture image frames at a first speed. The pre-processing circuitry may be configured to perform one or more operations on the image frames captured by the photo sensor array. The pre-processing circuitry may be additionally configured to effect transfer of at least some of the image frames to the image decoding system via the communication interface at a second speed. The first speed may be greater than the second speed.

A camera interface circuit for a barcode scanner includes a binary conversion block and a selection module. The binary conversion block receives image signals from a camera, and converts gray levels of each pixel in each image frame into binary codes. The selection module alternately provides binary codes of one image frame and image signals of a consecutive image frame as outputs.

A scale and scanner system includes a controller to control operation of the scale and scanner system. A scale calibration parameter memory for storing scale calibration parameters is coupleable to the controller. A scanning module and a scale module are coupleable to the controller. When the controller is not coupled to the scanning module or scale module, the scale calibration parameter memory remains in the system.

A code reader may include a light source configured to illuminate a target area in which items are to be located for reading machine-readable indicia associated with the items, an image sensor configured to capture an image of the target area, an illumination drive circuit in electrical communication with the light source, and an image capture circuit. The image capture circuit may be configured to (i) enable and disable the image sensor to capture an image of the target area during the high illumination and a portion(s) of the low illumination of the target area, and (ii) read an image captured by the image sensor. The illumination drive signals may cause the illumination drive circuit to generate a high illumination drive signal to cause the light source to produce a high illumination, and generate a low illumination drive current to cause said light source to produce a low illumination.

A barcode-reading system may include a barcode reader and at least one detector that is configured to detect a characteristic of an environment in which the barcode-reading system is located. The barcode-reading system may also include a controller that is configured to adjust at least one output of the barcode-reading system based on at least one detected characteristic.

An indicia-reading system is provided that incorporates a hybrid approach to decoding indicia such as barcodes. An indicia-capturing subsystem acquires information about indicia within the indicia-capturing subsystem's field of view. An indicia-decoding module decodes indicia information acquired by the indicia-capturing subsystem. The indicia-decoding module includes a primary, basic signal processor for initially decoding indicia information, and a secondary, advanced signal processor for decoding indicia information that is not decoded by the primary, basic signal processor.

A scale and scanner system includes a controller to control operation of the scale and scanner system. A scale calibration parameter memory for storing scale calibration parameters is coupleable to the controller. A scanning module and a scale module are coupleable to the controller. When the controller is not coupled to the scanning module or scale module, the scale calibration parameter memory remains in the system.
