First Claim
Patent Images
1. A bar code reading device comprising:
- a two-dimensional image sensor array comprising;
a first subset of pixels comprising a plurality of monochrome pixels; and
a second subset of pixels;
wherein the first subset of pixels is configured to be addressed independently of the second subset of pixels by the device to read out a plurality of monochrome pixel values;
wherein the device is configured to interpolate one or more missing pixel values based upon at least a portion of the monochrome pixel values;
wherein the one or more missing pixel values correspond to positions of one or more pixels from the second subset of pixels; and
wherein the device is configured to generate a frame of image data based upon the plurality of monochrome pixel values and the one or more missing pixel values.
