摘要:
An asymmetric aperture device for a camera is provided that improves light gathering properties by increasing both the light gathering opening of the aperture and the number of light producing light sources placed on the aperture. An asymmetric aperture design is provided that utilizes a significantly larger portion of the camera lens. The tradeoff between the competing objectives of maximizing camera depth of field and maximizing the production of useful focus-condition information within the camera image is optimized. More illumination is provided without significantly increasing the lateral size of the illuminator pattern.
