A bar code reading apparatus, the apparatus comprising:
- a two-dimensional CMOS image sensor array comprising a plurality of pixels, wherein the plurality of pixels are disposed in a plurality of rows, the plurality of pixels being operable in a global shutter mode of operation, wherein each pixel of the plurality of pixels comprises:
- a photodetector;
- a floating diffusion;
- and
- an opaque optical shield, wherein the opaque optical shield is configured to shield at least the floating diffusion, such that the photodetectors of the plurality of pixels are configured to be exposed to light in the global shutter mode of operation without the light causing modulation of charges stored in the floating diffusion;
- a memory storing instructions that, when executed by a processor, configure the apparatus to:
- capture one or more frames of two-dimensional image data using the plurality of pixels in the global shutter mode of operation;
- and
- decode one or more decodable indicia, including a two-dimensional bar code, in the one or more frames of two-dimensional image data.
A method for operating an apparatus, the apparatus comprising a two-dimensional CMOS image sensor array comprising a plurality of pixels, wherein the plurality of pixels are disposed in a plurality of rows, the plurality of pixels being operable in a global shutter mode of operation, wherein each pixel of the plurality of pixels comprises a photodetector, a floating diffusion, and an opaque optical shield, wherein the opaque optical shield is configured to shield at least the floating diffusion, such that the photodetectors of the plurality of pixels are configured to be exposed to light in the global shutter mode of operation without the light causing modulation of charges stored in the floating diffusion;
- the method comprising:
- capturing one or more frames of two-dimensional image data using the plurality of pixels in the global shutter mode of operation;
- and
- decoding one or more decodable indicia, including a two-dimensional bar code, in the one or more frames of two-dimensional image data.
