IMPROVED IMAGING METHOD AND APPARATUS |
摘要 |
A method of correcting errors in the output of an image detector is disclosed. The method comprises measuring an output signal (Vm) of a capacitor (Csh) holding a voltage corresponding to a signal detected by the image detector; comparing the value of output signal (Vm) to the value of the previously measured output signal (Vm-1) of the capacitor (Csh); calculating the error in the output signal (Vm) using a predetermined correction factor and the difference between the value of the output signal (Vm) and the value of the previously measured output signal (Vm-1); and providing a corrected output value (Vcrt) in accordance with the calculated error. Detectors, methods of calibrating detectors, image correction apparatus and guidance systems comprising the detectors are also disclosed. |

1. A method of correcting errors in the output of an image detector comprising the steps of:
measuring an output signal (Vm) of a capacitor (Csh) holding a voltage corresponding to a signal detected by the image detector; comparing the value of output signal (Vm) to the value of the previously measured output signal (Vm-1) of the capacitor (Csh); calculating the error in the output signal (Vm) using a predetermined correction factor and the difference between the value of the output signal (Vm) and the value of the previously measured output signal (Vm-1); and providing a corrected output value (Vcrt) in accordance with the calculated error. |
