Display apparatus and electronic camera

An electronic camera comprising:

• an imaging device for converting light from a subject into an image signal;
• an imaging unit for obtaining image data representing the subject by driving the imaging device;
• a display unit;
• a video signal generator for controlling the imaging unit to intermittently drive the imaging device, intermittently converting the image data obtained through the imaging device and the imaging unit into a video signal, and intermittently outputting the video signal;
• and
• a display unit driver for intermittently receiving the video signal from the video signal generator and applying the video signal and drive pulses to the display unit;
• wherein, while the display unit driver does not receive the video signal from the video signal generator, the display unit driver suspends applying of at least a part of the drive pulses to the display unit and maintains a currently-displayed image on the display unit.

An electronic camera comprising:

• an imaging device for converting light from a subject into an image signal;
