Abstract: A miniature barcode reading module for an electronic device minimizes the size of the memory of the processor die allowing the module to be used in small form factor electronic devices. The module may include an image sensor package operative to scan a barcode and a processor die coupled to the image sensor package. The processor die may include a processor, a memory, a flash memory, a plurality of barcode scanning algorithms loaded into the flash memory, and an image capture port operatively connected to the image sensor package. Barcode scanning firmware can determine if a barcode decoding algorithm is loaded in the memory, determine if the loaded barcode decoding algorithm is a correct barcode decoding algorithm or an incorrect barcode decoding algorithm, unload an incorrect barcode decoding algorithm from the memory, and load a correct barcode decoding algorithm into the memory.

Abstract: A terminal for measuring at least one dimension of an object includes at least one imaging subsystem and an actuator. The at least one imaging subsystem includes an imaging optics assembly operable to focus an image onto an image sensor array. The imaging optics assembly has an optical axis. The actuator is operably connected to the at least one imaging subsystem for moving an angle of the optical axis relative to the terminal. The terminal is adapted to obtain first image data of the object and is operable to determine at least one of a height, a width, and a depth dimension of the object based on effecting the actuator to change the angle of the optical axis relative to the terminal to align the object in second image data with the object in the first image data, the second image data being different from the first image data.

Abstract: 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.

Abstract: The present invention embraces an optical indicia reader, e.g., barcode scanner, that captures images of optical indicia under multiple imaging conditions within the span of a single frame. The reader includes an image sensor having selectively-addressable pixels that can be divided into groups having regions of interest (ROIs) within the reader field of view. Each pixel group is shuttered separately to obtain independent partial frame images under separate imaging conditions.

On the upper face, the sensor die is provided with a sensor array, an analog-to-digital conversion module, a digital logic circuit, and a timing and clock control circuit.

Each submodule is disposed adjacent to the sensor array and positioned on opposing sides of the sensor array. The digital logic circuit forms a first row. The timing and clock control circuit and the analog signal processing circuit are adjacent and form a second row. The first and second rows have similar dimensions and are disposed on opposite sides of the sensor array.

The processor is communicatively coupled to the two dimensional image sensor, the three dimensional depth sensor, and the autofocusing lens assembly.

The image capture mode is configured to output captured images to the analog-to-digital converters, which are configured to send the digital data to the processor. The processor is configured to switch from scene sensing mode to image capture mode based upon the scene sensing mode output results.
