Abstract:
1. A method of addressing imagers, comprising: providing a bi-directional bus; providing an array of imagers arranged in n rows and m columns wherein said n and m are positive integers, wherein each said imager is connected to said bi-directional bus, wherein each said imager has a Vmode terminal, wherein each said imager has a select terminal, and wherein each said imager can deliver a signal to said bi-directional bus only when a first selecting signal is applied to a Vmode terminal of that said imager and a second selecting signal is applied to a select terminal of that said imager simultaneously; providing a first multiplexer having a vertical select input and n outputs, wherein each of said n outputs is connected to one of said Vmode terminals of said imagers; providing a second multiplexer having a horizontal select input and n×m outputs wherein each said output is connected to said select terminal of one of said imagers; applying a vertical input signal to said vertical select input of said first multiplexer thereby producing said first selecting signal at one of said Vmode output lines; and applying a horizontal input signal to said horizontal select input of said second multiplexer thereby sequentially producing said second selecting signal at said select terminal of one of said imagers.
