## Abstract

An image capturing device employing as illumination source(s) (flash apparatus(es)) a plurality of light emitting diodes emitting light of different colors; wherein such light emitting diodes are respectively made to emit light in pulsed fashion in turn by emitted color during exposure time(s). Furthermore, during exposure time(s), such light emitting diodes may be made to sequentially emit light in pulsed fashion in turn by emitted color, and/or such light emitting diodes may be made to sequentially emit light in pulsed fashion in turn by emitted color over multiple iterations.

## Claims

### Claim 1

A LED device comprising:
a LED element;
a first lead frame mounting the LED element; and
a second lead frame;
wherein a thickness of a region for mounting the LED element in the first lead frame is thicker than other locations in the first lead frame.

### Claim 2 (depends on 1)

The LED device according to claim 1, wherein the first lead frame and the second lead frame are arranged in mutual opposition.

### Claim 3 (depends on 1)

The LED device according to claim 1, wherein a plurality of the LED elements including a red LED element, a green LED element and a blue LED element are mounted.

### Claim 4 (depends on 1)

The LED device according to claim 1, wherein the thickness of the region for mounting the LED element in the first lead frame is from 0.5 mm to 0.6 mm, and the thickness at the other locations in the first lead frame is 0.3 mm.
