摘要： A plurality of solid-state imagers is mounted in a reader, such as a bioptical, dual window, point-of-transaction workstation, for capturing illumination light returning along different fields of view from indicia. A controller controllably activates the imagers over respective exposure time periods during which the indicia are illuminated to produce electrical signals indicative of the indicia being read, processes the electrical signals to read the indicia, and controls the exposure time periods to be nonconcurrent to prevent interference among the imagers.

摘要： An imager in an imaging reader captures light from a target, generates image data from the captured light, and generates a pixel clock signal having a pixel clock frequency in synchronism with the image data. A controller is connected via an electrical conductor to the imager, and controls the imager to transfer the image data, receives the image data, and processes the image data. A circuit suppresses electromagnetic radiation generated by the conductor during the image data transfer, and includes a spread spectrum modulator for modulating the pixel clock signal to generate a variable spread spectrum signal having a spread spectrum frequency that periodically varies above and below the pixel clock frequency, and a buffer having a plurality of registers for receiving and temporarily storing the image data, and for varying as a function of the spread spectrum frequency how much of the image data is being temporarily stored.

摘要： Interleaving multiple logical data streams into one physical data stream reduces overhead required to process the multiple logical data streams. Multiple arrays of data values are interleaved into a combined array of data that simulates a frame of data for input to a data port such as a video port. Revised timing and synchronization signals are provided to permit transmission of the combined array according to video data port protocol. The processor includes instructions for locating the various arrays of data values within the combined array.
