Abstract:
1. An indicia reading terminal comprising: an image sensor integrated circuit, the image sensor integrated circuit including a two-dimensional image sensor array comprising a plurality of selectively-addressable pixels, the image sensor integrated circuit further including analog-to-digital conversion circuitry for converting analog signal pixel values into digital signal pixel values, and the image sensor integrated circuit configured to output image data in a first data format; an imaging lens assembly for focusing an image of a target onto the two-dimensional image sensor array of the image sensor integrated circuit; a memory; a microprocessor integrated circuit, the microprocessor integrated circuit comprising a central processing unit (CPU) and at least one data interface for receiving data in a second data format, the microprocessor integrated circuit operative to transfer image data received by the at least one data interface into the memory of the indicia reading terminal, and the CPU operative for executing a decoding algorithm, the decoding algorithm for processing image data in the memory for attempting to decode at least one symbol represented in the memory; and a data formatting circuit for receiving image data in the first data format output from the image sensor integrated circuit, for converting the received image data in the first data format to image data in the second data format, and for providing the image data in the second data format to the at least one data interface of the microprocessor integrated circuit; wherein the indicia reading terminal has a first mode of operation and a second mode of operation; wherein responsive to a trigger signal activation with the first mode of operation active, image signals are read out from the image sensor array for capture of a frame of image data having a first picture size and the indicia reading terminal reads-out the image signals at a first pixel clock speed for processing the image data; and wherein responsive to a trigger signal activation with the second mode of operation active, image signals are read out from the image sensor array for capture of a frame of image data having a second picture size and the indicia reading terminal reads-out the image signals at a second pixel clock speed, wherein the first picture size is larger than the second picture size and wherein the first pixel clock speed is slower than the second pixel clock speed.
