ABSTRACT:
An imaging apparatus includes an electron emission array having electron sources arranged in matrix form and having a plurality of horizontal scan lines, a photoelectric conversion film opposed to the electron emission array, and a control and drive circuit configured to select one or more of the horizontal scan lines in a given video signal output period and to cause the electron sources included in the selected one or more horizontal scan lines to emit electrons toward the photoelectric conversion film to produce a video signal, wherein the control and drive circuit is configured to cause the electron sources included in unselected one or more horizontal scan lines not selected in the given video signal output period to emit electrons toward the photoelectric conversion film in a blanking period immediately preceding the given video signal output period.
