Image sensors and driving methods thereof

A driving method of an image sensor, the image sensor including a substrate, an organic photoelectric film on the substrate and configured to perform photoelectric conversion of incident light, and a plurality of pixel electrode lines between the substrate and the organic photoelectric film, the plurality of pixel electrode lines arranged in a first direction, each pixel electrode line of the plurality of pixel electrode lines including a separate linear sequential pattern of pixel electrodes, each linear sequential pattern extending in a second direction intersecting the first direction, the method comprising:

• scanning a pixel electrode line, of the plurality of pixel electrode lines, that is a read line, from which pixel information is read among the plurality of pixel electrode lines, in a first side of the first direction;
• moving a photoelectric conversion ON region including a separate pixel electrode line, to which an on-voltage associated with performing the photoelectric conversion is applied among the pixel electrode lines, in the first side of the first direction in synchronization with a timing of scanning the read line in the first side of the first direction;
• and
• applying an off-voltage associated with stopping the photoelectric conversion to at least one pixel electrode line that is external to the photoelectric conversion ON region among the plurality of pixel electrode lines.
