Imaging apparatus having electron source array

An imaging apparatus, comprising:

• 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 further configured to cause the electron sources included in the selected one or more horizontal scan lines to emit electrons toward the photoelectric conversion film in any one or more blanking periods excluding both a blanking period immediately following the given video signal output period and a blanking period immediately preceding a next video signal output period in which the one or more horizontal scan lines will be selected next time.
