Abstract:
1. An image sensor based terminal comprising: an image sensor having an image sensor pixel array, the image sensor pixel array having a plurality of pixels; a lens assembly for use in focusing an image onto the image sensor pixel array; and a hand held housing, wherein the image sensor based terminal is configured so that the image sensor pixel array is supported within the hand held housing; wherein the image sensor is a multiple state image sensor pixel array having a logarithmic output state in which an active output response curve for the image sensor pixel array includes a logarithmic pattern and a linear output state in which an active output response curve of the image sensor pixel array defines a substantially straight linear pattern extending a range of possible illumination levels to an illumination level resulting in saturation of the image sensor pixel array; wherein the terminal is operative in an operator initiated mode of operation in which there is output from the image sensor pixel array for processing a succession of frames having image information, the image sensor based terminal further being operative so that a first subset of the succession of frames are output from the image sensor pixel array with the logarithmic output state of the image sensor active, and further being operative so that a second subset of the succession of frames are output from the image sensor pixel array with the linear output state of the image sensor active, wherein the image sensor based terminal processes a frame of the succession of frames to attempt to decode decodable indicia.
