There is provided in one embodiment an indicia reading apparatus with enhanced functionality which can filter image data prior to the capture of image data into an image frame memory for further processing. In one aspect the indicia reading apparatus can have an image sensing and processing circuit that can contemporaneously output, on respective first and second interfaces, both filtered and raw pixel values so that both filtered and raw frames of image data can be captured contemporaneously for further processing. Filtered and raw frames of image data or pixel values can also be serially output through a single interface in an interleaved manner. An image sensing and processing circuit which outputs either or both raw and filtered pixel values can be provided on a single integrated circuit. In another aspect an image sensing and processing circuit can be provided that develops data indicating a location of a decodable indicia representation within image data prior to capture of a frame of image data into an image frame memory so that when pixel values are first addressed for further processing, a decodable indicia representation such as a bar code representation has already been located. By processing of image data within an image processing circuit prior to capture into an image frame memory a trigger to read time (TTR) can be reduced.
