Embodiment Construction

[0025] The present disclosure relates to measuring tooth whiteness, and more particularly to a camera fixture for measuring tooth whiteness using a hand-held camera. Apparatuses and methods according to aspects of the present disclosure provide a camera fixture that prevents ambient lighting conditions from interfering with recording images (eg, still photos or videos) of a user's (eg, consumer's) teeth with a camera. More specifically, when recording images of a user's teeth using a hand-held camera inserted into the disclosed camera holder, essentially the only source of light reaching the teeth and camera lens is the camera's built-in light source (eg, a flash). Furthermore, according to aspects of the present disclosure, the camera jig aligns the camera lens with the same target (ie, one or more teeth) at the same distance throughout multiple uses. Thus, the camera fixture disclosed herein enables its user to capture images of the same target location under consistent ligh...

Abstract

The present invention provides apparatuses and methods for producing improved photographs suitable for measuring teeth whiteness with a handheld camera using a camera jig. The camera jig includes a base that contacts a surface. The camera jig also includes a light shield made from a tubular structure defining an interior cavity. The camera jig further includes a slot in the tubular structure thatsupports the handheld camera at a predetermined distance from a target, which may be teeth of a user. The slot aligns a lens of the handheld camera with the target. Further, the light shield blocks substantially all ambient light, other than light of a light source of the handheld camera, from the target as it is photographed.

Description

Background technique [0001] There are a variety of at-home oral care systems on the market that consumers can use to whiten their teeth. These systems include whitening trays, whitening pens, whitening strips, whitening mouthwash, and whitening toothpaste. Some products offer printed reference cards with multiple tooth shades to help consumers track their whitening progress. But such cards are inconvenient to use because consumers have to make multiple comparisons to find the card that best matches the color of their teeth. Furthermore, since such cards rely on the consumer's choice of teeth and their judgment of the best match, the results are subjective. Also, because consumers may attempt to use the cards under different lighting conditions, results may vary over time due to changes in the color and intensity of ambient lighting. Contents of the invention [0002] Embodiments of the present disclosure provide a jig for a handheld camera including a lens and a light sou...
