Abstract
A light-incorporated video camera incorporating a video light integrally in a video camera, includes: a video light input switch for instructing turn-on of the video light; and a timer; wherein the video light turned on by instruction from the video light input switch is automatically turned off after the elapse of a time set on the timer. If a switch key of the video camera is operated before the time set on the timer expires, the timer is initialized to continue the turn-on state of the video light. In this video camera, preferably, the switch key is a record/stop switch key of the video camera, the video light is a tungsten halogen lamp, and the timer is a five-minute timer.
Claims14
A light-incorporated video camera incorporating a video light integrally in a video camera, comprising:
- a first switch for individually instructing a second switch to turn-on said video light so as to enable a user to separately turn-on said video light;
- a timer;
- an illuminometer;
- and
- a central processing unit (CPU) for controlling said second switch based on input information from said first switch, information from said timer and information from said illuminometer;
- wherein said CPU starts said timer and also turns on said second switch to turn on said video light when turn-on of said video light is instructed from said first switch and it is determined that lighting is necessary based on illuminance of an object measured by said illuminometer, and, when a time set on said timer expires, said CPU turns off said second switch to turn off said video light;
- and
- said video light is maintained in a turned-on state if said CPU determines that a record/stop switch of said video camera is on.

- wherein said CPU starts said timer and also turns on said second switch to turn on said video light when turn-on of said video light is instructed from said first switch, and, when a time set on said timer expires, said CPU turns off said second switch to turn off said video light;
- and
- said video light is maintained in a turned-on state if said CPU determines that a record/stop switch of said video camera is on, by means of said CPU initializing said timer when it is determined that said record/stop switch is on, thereby preventing said timer from expiring.
