Spatially incoherent single channel digital Fourier holography

Abstract: We present a new method for recording digital Fourier holograms under incoherent illumination. A single exposure recorded by a digital camera is sufficient to record a real-valued hologram that encodes the complete three-dimensional properties of an object.

Storable digital camera associated with a computer system

Abstract: A digital camera may include a portion that is translatable into and out of a computer system housing The camera portion may be mounted such that when pushed inwardly into the housing from a stored position, the camera portion automatically springs outwardly from the housing and is ready for use The camera may be operated “on” by the act of causing the camera portion to spring to its outwardly oriented position Once outside of the computer housing, the camera portion may be rotated to adjust the direction of focus of the camera

Pointing device for digital camera display

Abstract: A process and apparatus is described to improve a digital camera user interface and increase ease of use and functionality of a digital camera by quickly, accurately and robustly permitting cursor control and designation in a digital camera display. A digital camera is used as a pointing device such as a mouse or trackball. The motion of the camera is detected, and the motion of the camera is used to position graphic elements on the camera's own display. The camera's motion can be detected with sensors, such as gyroscopes, or the camera itself can be used as a motion sensor. One application of this involves using the camera as a computer mouse, or like a gun-sight, to select images from a sheet of low-resolution (“thumbnail”) images. The motion of the camera is tracked, and the user aims at the desired image from a sheet of thumbnail images. The thumbnails appear to be fixed relative to the world because the camera can continuously reposition them in the display based upon the motion of the camera. The user can then select a thumbnail in an intuitive manner by simply pointing the camera at the desired thumbnail. For alternative embodiments, the interface can be used to select regions of greater extent than can be viewed in the viewer or to virtually review images.

Digital camera zooming based on unified CFA image processing steps

Abstract: A unified camera image processing system that performs zooming and full color image reconstruction for single-sensor digital cameras is introduced. Compact and low-cost single-sensor solutions often lack optical zooming capabilities and thus depend on digital techniques. However, the computational power required for high-quality output using traditional techniques is generally too prohibitive to implement in such devices. The proposed scheme employs a small number of reusable, low-complexity operations and a consistent color model throughout to achieve high-quality zoomed output that is practical for hardware implementation. The high-level system components are color filter array (CFA) zooming, CFA interpolation (demosaicking) and demosaicked image postprocessing. The resulting output is consistently superior to other methods.

High Dynamic Range Imaging and its Application in Building Research

Abstract: This article describes the theory and application of high dynamic range imaging (HDRI). HDRI is a recent technology allowing the capture of images with a much extended dynamic range whose values represent real-world luminance rather than just arbitrary pixel values. This article lays out the steps necessary to create HDR images, and highlights recent developments in the technology and its applications for building research.
