Abstract

The present invention provides an image-taking apparatus which includes: a first light-emitting section having a xenon tube and a main capacitor; and a second light-emitting section having an LED. When an image is to be taken with an auxiliary light emission immediately after power-on and immediately after previous image taking with a previous auxiliary light emission, recharge of the main capacitor is not completed yet. In such a case, the image-taking apparatus selects the second light-emitting section to emit auxiliary light from the LED.

Claims (11)

1. An image-taking apparatus which generates image signals by forming a subject image on an imaging device through an image-taking optical system, the apparatus comprising:

a first light-emitting section which has a xenon tube and a main capacitor, and accumulates charge in the main capacitor so as to emit auxiliary light to a subject when an image is taken;

a second light-emitting section which has an LED and emits auxiliary light to a subject when an image is taken;

a full-charge sensor which detects whether recharge of the main capacitor is completed or not; and

a light-emission controlling section which causes the second light-emitting section to emit light when an image is taken with an auxiliary light emission in a state where recharge of the main capacitor is incomplete.

2. An image-taking apparatus which generates image signals by forming a subject image on an imaging device through an image-taking optical system, the apparatus comprising:

a first light-emitting section which has a xenon tube and a main capacitor, and accumulates charge in the main capacitor so as to emit auxiliary light to a subject when an image is taken;

a second light-emitting section which has an LED and emits auxiliary light to a subject when an image is taken;

a full-charge sensor which detects whether recharge of the main capacitor is completed or not;

a distance measuring section which measures a distance to subject; and

a light-emission controlling section which causes the second light-emitting section to emit light when a distance to subject is shorter than a predetermined distance and recharge of the main capacitor is incomplete, and which causes the first light-emitting section to emit light when a distance to subject is equal to or longer than the predetermined distance and recharge of the main capacitor is completed, when an image is taken with an auxiliary light emission.
