Color measurement jig

1. A jig for a handheld camera comprising a lens and a light source, the jig comprising:

a base configured to be positioned over a surface;

a light shield comprising a tubular structure defining an interior cavity, the tubular structure comprises a toothpaste carton, and

a slot in the light shield configured to removably receive and support the handheld camera at a predetermined distance from the surface, the slot formed as an opening extending into the jig from an outer wall thereof by a predetermined depth,

wherein:

the slot is proportioned to position the lens and the light source in the interior cavity and to align the lens of the handheld camera with a target,

the slot comprises a removed section of the toothpaste carton, and

the light shield blocks substantially all ambient light from the target.

2. The jig of claim 1 , wherein:

the base comprises an arch shape;

the surface comprises buccal surfaces of teeth of the user; and

the target comprises one or more of the teeth.

3. The jig of claim 1 , wherein the tubular structure comprises a first end abutting the base and a closed second end.

4. The jig of claim 1 , wherein the slot in the light shield is substantially perpendicular to a central axis of the jig.

5. The jig of claim 1 , wherein:

the slot comprises:

a first surface that directly contacts a lens-side surface of the handheld camera; and

a second surface that directly contacts a backside of the handheld camera,

a distance from a bottommost surface of the base to the first surface corresponds to a minimum focusing distance of the handheld camera, and

the slot receives the handheld camera in a snug manner that blocks substantially all ambient light from entering between the slot and the handheld camera.

6. The jig of claim 1 , further comprising:

a window in the base,

wherein the slot aligns the lens with the target and the window.

7. A camera jig comprising:

a bottom surface including a window;

a top surface; and

a tubular structure connecting the top surface and the bottom surface, the tubular structure defining an interior cavity between the top surface and the bottom surface,

wherein:

the tubular structure comprises a slot substantially perpendicular to a central axis of the camera jig, the slot formed as an opening extending into the jig from an outer wall thereof by a predetermined depth;

the slot aligns a lens of a handheld camera with the window and a target at a distance corresponding to a minimum focusing distance of the handheld camera; and

the camera jig blocks substantially all ambient light from reaching the target.

8. The camera jig of claim 7 , wherein:

the top surface is an entirely closed surface;

the bottom surface comprises an arched shape; and

the target comprises at least one tooth in a mouth of a user.

9. The camera jig of claim 7 , wherein the tubular structure comprises a toothpaste carton.

10. A method comprising:

forming the base of a camera jig by removing a portion of a toothpaste carton below a first predetermined location, such that the base is formed at the first predetermined location, the camera jig including a base and a slot;

forming the slot of the camera jig by removing a partial section from the toothpaste carton at a second predetermined location, the predetermined location being at distance equal to or greater than a minimum focusing distance of the handheld camera;

positioning the base of the camera jig over buccal surfaces of one or more teeth of a user;

after positioning the base of the camera jig over the buccal surfaces, inserting a handheld camera into the slot of the camera jig, the handheld camera including a lens and a light source, wherein inserting the handheld camera in the slot of the camera jig comprises:

placing the lens and the light source inside of the camera jig;

aligning the lens with the one or more teeth; and

blocking, by the camera jig, substantially all ambient light, other than light emitted from the light source, from the one or more teeth; and

capturing, using the handheld camera, an image of the one or more teeth through the base of the camera jig.

11. The method of claim 10 , wherein forming the slot of the camera jig comprises removing a partial section of the toothpaste carton that is approximately equal to a thickness of the handheld camera and having a depth corresponding to a location of the lens of the handheld camera.

12. The method of claim 10 , further comprising viewing the image on a viewfinder display, the viewfinder display located substantially outside the camera jig.
