Imaging system

1. An imaging system, comprising:

an optical system;

a shutter button; and

a housing including the optical system, wherein

a lens which is a convex lens located on a most object side in the optical system,

the convex lens projects from a part of the housing which is between the shutter button and the convex lens, and

a center of the imaging system is disposed between a gravity center of the imaging system and the convex lens.

2. The imaging system according to claim 1 , further comprising:

an imaging body including the optical system and an imaging element; and

a power supplier that supplies power to the imaging element, wherein

the center of the imaging system is disposed between a gravity center of the power supplier and the convex lens.

3. The imaging system according to claim 2 , wherein a weight m of the imaging body and a weight M of the power supplier satisfy the following condition: m<M.

4. An imaging system, comprising:

an imaging body including an optical system and an imaging element;

a shutter button;

a power supply that supplies power to the imaging element;

a housing including the imaging body, the shutter button, and the power supply,

wherein:

a lens located on a most object side in the optical system projects from a part of the housing between the shutter button and the lens, and

a distance AN between a gravity center A of the imaging body and a center N of a shape of the imaging system and a distance BN between a gravity center B of the power supplier and the center N of the shape of the imaging system satisfy a condition AN>BN.

5. The imaging system according to claim 4 , wherein the power supply includes a battery.
