Abstract:
1. An imaging apparatus comprising: an XY address scanning-type imaging device; and a controller for controlling the electronic shutter speed, wherein each time when a brightness and a color temperature of a subject imaged by the imaging apparatus have a variation greater than a predetermined amount, the controller implements a detecting mode for detecting a presence of a fluorescent-lamp illumination, wherein each time when the imaging apparatus is turned on, the controller implements the detecting mode for detecting the presence of the fluorescent-lamp illumination, wherein the controller determines whether a photographic environment of the imaging apparatus is indoor or outdoor, and when an outdoor photographic environment is determined, the controller turns off the detecting mode; wherein, when a set vertical synchronization frequency of the imaging apparatus is denoted as fv (Hz) and N is a positive integer, in a case where 120/fv is an integer, said controller sets said electronic shutter speed to an electronic shutter speed at which the exposure time becomes N/120 seconds, and in a case where 100/fv is an integer, said controller sets said electronic shutter speed to an electronic shutter speed at which the exposure time becomes N/100seconds, and wherein the controller alternatively increases or decrease each vertical period by a same period upon detecting a photographic environment of the image apparatus.
