Imaging apparatus and method of controlling the same

摘要

An imaging apparatus includes an image sensor having a plurality of light receivers that receive light, a detector to detect a monitoring voltage which corresponds to a difference between a dark voltage corresponding to dark current generated from at least one of the plurality of light receivers and a predetermined reset voltage, and a controller to reset the image sensor if the monitoring voltage detected by the detector becomes lower than a threshold voltage. Accordingly, the imaging apparatus can perform divided exposure promptly and accurately to minimize the problem occurring due to dark current.

1. An imaging apparatus comprising:
an image sensor configured to have a plurality of light receivers that receive light; a detector configured to detect a monitoring voltage which corresponds to a difference between a dark voltage corresponding to dark current generated from at least one of the plurality of light receivers and a predetermined reset voltage; and a controller configured to reset the image sensor if the monitoring voltage detected by the detector becomes lower than a threshold voltage, wherein the controller repeatedly resets the image sensor whenever the monitoring voltage becomes lower than the threshold voltage while the at least one of the light receivers receives the light, and the threshold voltage is a voltage that is set to correspond to a predetermined photo-sensing speed.
