Combined photogate and photodiode active pixel image sensor |
摘要 |
An active pixel image sensor includes an array of pixels arranged in a first group and a second group. The first group may constitute a row and the second group may constitute a column, for example. A first common conductor is coupled to the pixels in the first group for conducting control signals. A second common conductor is coupled to the pixels in the second group for selectively transmitting signals to processing electronics. Each of the pixels includes a plurality of sensing elements that are each configured for capturing a portion of energy from an object to be imaged. At least one of the sensing elements is of a type distinct from another of the sensing elements. For example, one of the sensing elements may be a photogate and another may be a photodiode. An amplifying arrangement is provided for receiving signals from selected ones of the plurality of sensing elements and for selectively providing output signals to the second common conductor.
