摘要:
A digital imaging system, such as an active pixel sensor (APS) system, includes an array of sensors arranged into lines that form rows and columns. Each sensor in the array includes a photosensor that collects electric charge when exposed to light. Each sensor also includes a select circuit that generates an output signal indicating the amount of charge collected by the photosensor during a given time, and a reset circuit that clears collected charge from the sensor at a selected time. The APS system also includes a line decoder circuit that produces select and reset signals and delivers the signals to the select circuits over control lines. Each control line connects to two adjacent lines, e.g., rows or columns, of the array, delivering a select signal to the image sensors in one of the two lines and delivering a reset signal to the image sensors in the other line.
