Abstract:
1. A video camera, comprising: an imager, having an imaging surface irradiated with an optical image representing a scene, which outputs electronic images corresponding to the optical image with a first period; a determiner which determines whether or not a flicker occurs based on the electronic images outputted from said imager; a processor which executes a flicker countermeasure process when a determination result of said determiner indicates occurrence of the flicker; a calculator which calculates a variation amount of the scene based the electronic images outputted from said imager with a second period which is longer than the first period; an activator which activates said determiner in a case where the variation amount calculated by said calculator exceeds a reference; and a suspender which suspends said determiner being activated by said activator in response to an output of a determination result indicating non-occurrence of the flicker from said determiner or a completion of the flicker countermeasure process.
