An image-capturing apparatus is capable of capturing a three-dimensional image and a high quality panoramic image as the need arises, and is portable if it is used as a single lens camera that captures a normal two-dimensional image. A second image-capturing unit having an image-capturing optical system is detachably connected to a first image-capturing unit, which is capable of functioning as an image-capturing apparatus by itself, through joints and a connector. The second image-capturing unit can extensively connect to other units, which have the similar connecting structure. Information is transmitted between the units through a slot for an external storage device. The positions of images captured by the second and subsequent image-capturing units can be adjusted with respect to an image captured by the first image-capturing unit. In synchronism with release signals from the first image-capturing unit, the other units are driven to capture the images at the same time or continuously.

An apparatus and method are disclosed wherein a depth map is generated using a single camera (e.g., single lens of a camera) and multiple images are captured by the camera. In one example, a single digital camera is used to capture a set of images corresponding to a set of lens positions based on lens position data. In this example, the lens position data may be either uniform or nonuniform lens position data. The method and apparatus determines focus metric information for each of a plurality of regions of interest in each image of a set. A determination is made of a best lens position for each of the regions of interest based on the focus metric information from the images in the set and are stored as data in a depth map. Image generation operations are then performed based on the generated depth map, such as determining whether or not to use a flash to capture a final image, to determine a type of color operation to be performed on the final image, or any other suitable image generation operation. In one example, the depth map is generated by selecting a best focus metric among the various images that were captured for a particular region of interest. Once the depth map is generated using data from the multiple images, depth map based control logic then determines how to use the depth map to effect an image processing operation. Among other advantages, multiple cameras need not be employed nor do external light sensors need be employed to generate a depth map for use in image processing operations. Other advantages will be recognized by those of ordinary skill in the art.

An improved lens with Rugate filter specifically designed to be worn in prescription and non-prescription glasses, contact lenses, intraocular lenses and sunglasses, and to provide protection against macular degeneration by reducing harmful visible blue light transmission and ocular photochemical damage. The lens at least includes a single lens layer with a Rugate filter deposited thereon to selectively block visible blue light. Other layers may be added including a polarizing layer, dielectric layer and/or color tint in a lens sandwich configuration, to additionally give a high degree of UVA and UVB protection, color contrast, and glare reduction. The Rugate filter is a stop band which yields an exceptional light transmission profile under all light conditions, thereby maximizing protection as well as clarity of vision. In the multi-layer embodiment, all of the lens layers provide comprehensive protection for preventing macular degeneration, cataracts and other ocular injuries, yet maintain a balanced light transmission profile for visual acuity.

A system and method for efficiently performing a depth map recovery procedure includes an imaging device that is implemented in a single-lens stereo-shutter configuration for simultaneously capturing overlaid images corresponding to a photographic target. A depth map generator is configured to analyze the overlaid images to determine disparity values corresponding to separation distances between matching points in the overlaid images. The depth map generator then utilizes the disparity values to calculate depth values that correspond to locations in the photographic target. The depth map generator may then utilize the foregoing depth values for creating a depth map corresponding to the photographic target.

There is described a multi-configurational, multi-functional electrical lighting fixture for high-abuse application and structured for surface mounting. The fixture includes a lens of U.V. stabilized, high impact-resistant, injection molded polycarbonate plastics, integrally formed with two selective, separate and distinct, high-performance reflector/refractor surface systems carried by the single lens, as separate zonal areas. The first system generates a long and narrow "throw", and the second system a short and wide "throw". A molded, opaque "eyelid" provides optimum lamp shielding and controls light distribution. The lens surmounts a lens base to which it is secured by means of unique internal, integrally-molded lugs received in cooperating hook-shaped slots. An 0-ring gasket establishes a water-tight seal. Unlocking of the assembly is deterred by means of a single, tamper-resistant screw. The lens base is mounted on a deep casting, with or without an interposed cast aluminum baseplate. Alternatively, the lens base may be mounted directly on the cast aluminum baseplate, without the deep casting, to provide a low-profile fixture structure.

A camera is capable of both silver-halide shooting, through which object images are recorded on silver-halide film, and video shooting, although its distance measurement device is placed substantially in the same way and its mirror box has substantially the same size as in ordinary single-lens reflex cameras. In this camera, a pellicle mirror splits the light flux having passed through a taking lens into a first light flux and a second light flux, and a rotatable mirror switches the subsequent path of the second light flux between the optical path for a third light flux and the optical path for a fourth light flux. The pellicle mirror, through its light flux splitting function, directs the first light flux to a silver-halide shooting system, and directs the second light flux to the rotatable mirror. The rotatable mirror, through its optical path switching function, either directs the third light flux to an optical viewfinder system, or directs the fourth light flux to a video shooting system.
