| 1. An imaging apparatus comprising:
an electronic viewfinder; and
a controller,
wherein the electronic viewfinder includes a light source and a scanning unit for scanning light emitted from the light source,
and
wherein 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, and
wherein the controller independently controls the timing of turning on and off the light source and turning on and off the
scanning unit;
wherein 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 wherein, in response to the imaging apparatus being turned on, the scanning unit is turned on and the
light source is turned on after oscillation control of the scanning unit is stabilized.
