Abstract:
1. An image sensor for obtaining images, comprising: a light or radiation detector for detecting light or radiation by converting light or radiation information to charge information in response to incident light or radiation, and reading the charge information; a control device for controlling said detector to perform a reading operation for reading the charge information and a reset operation for resetting and discarding the charge information, during a frame cycle from a reading point of time for reading charge information collectively from a predetermined read area to a reading point of time for reading charge information collectively from a next predetermined read area; and a driving device for driving said detector by applying a driving signal to each line; wherein said control device performs controls to drive said detector in said reading operation by applying the driving signal to each line to read said charge information for said each line, and in said reset operation not to apply the driving signal simultaneously to adjacent lines; and wherein said lines are divided into a first set and a second set of alternate lines, said reset operation being carried out such that, while the driving signal is applied simultaneously to the first set of alternate lines, the driving signal is not applied to the second set of alternate lines, and that, while the driving signal is applied simultaneously to the second set of alternate lines, the driving signal is not applied to the first set of alternate lines.
