Abstract
An imaging apparatus including an electronic viewfinder comprising a light source, a scanning unit for scanning light emitted from the light source. The electronic viewfinder forms a two-dimensional image on a predetermined surface by synchronously modulating the light emitted from the light source with the operation of the scanning unit. The imaging apparatus further includes a controller capable of independently controlling the timing of turning on and off the light source and the timing of turning on and off the scanning unit. The controller controls the light source and the scanning unit in response to the on and off state of the power of the imaging apparatus so that when the light source is off the scanning unit is on.
