This invention is a lighting fixture to project even illumination onto flat panels. The fixture is a formed specular aluminum reflector with LEDs mounted to provide even and directed light, with modular connectors and power sources, allowing for variable lengths when combined with field adjustable housings and supports; or when mounted in a fixed length housing, to allow for linear lighting using any number of selectable lengths.

A digital still camera has a function to perform first and second exposures in a single imaging sequence. In the first exposure, imaging conditions are determined to obtain proper exposure amount of the background with available light. Then, the second exposure is carried out with the flashlight to illuminate the main subject.

A method and a system for obtaining visual information from an image sequence using a visual tunnel analysis are described. The present invention determines the position and orientation of rays captured in the image sequence and uses these rays to provide visual information. This visual information includes, for example, visual prediction information (whereby the extent of visibility and appearance of a virtual camera at arbitrary locations are determined) and visual planning (whereby a minimum number of images that need to be captured to visualize a desired region is determined). Generally, the visual tunnel analysis uses a subset of the plenoptic function to determine the position and orientation of every light ray passing through each point of images in the sequence. A visual tunnel associated with an input image sequence is a volume in visibility space that represents that portion of the visibility space occupied by the input image sequence. The visual tunnel is a representation of all light rays associated with the image sequence. The present invention encodes the orientation, appearance, and density of the available light rays at every point in free space.

This invention allows to shoot an image using correct object distance information and light emitting amount when the main light emitting amount upon shooting an object image is calculated by making the pre-light emission after the auto-focusing process. To this end, when a predetermined button independent of a release button is operated, a focusing process is executed first. Then, photometry is made while inactivating a strobe, i.e., under available light, and an exposure value is determined based on an object distance. Then, pre-light emission is made, light reflected by the object in the pre-light emission is measured, and the photometry result under the available light is subtracted from that in the pre-light emission, so as to obtain a brightness value of object reflected light of only the pre-light emission. This brightness value is corrected to be equal to lower than an allowable maximum value depending on the object distance to compute a main light emitting amount. After that, when the release button is operated, the strobe is driven on the basis of the determined main light emitting amount, and shooting is made using the determined exposure value.
