We have prototyped a new consumer imaging device, a remote camera, that leverages the mobile phone and provides a key capability not found in today’s digital still cameras and camera phones. Specifically our remote capture unit allows a user to capture images from a vantage point that would otherwise be impractical or socially unacceptable to use. We use a mobile phone as a view finder and a re...

Many kinds of digital devices can easily take motion images such as digital video cameras or camera-equipped cellular phones. If an image is taken with such devices under everyday situations, the resolution is not always high; moreover, hand vibration can cause blurring, making accurate recognition of characters from such poor images difficult. This paper presents a new character recognition al...

The fraction of absorbed photosynthetically active radiation (FPAR) is a key parameter in describing the exchange of fluxes of energy, mass and momentum between the surface and atmosphere. In this study, we present a method to measure FPAR using a digital camera and a reference panel. A digital camera was used to capture color images of low canopy vegetation, which contained a reference panel i...

Omnidirectional Vision Multiple images of a scene can be used to enhance the performance envelope of a scene captured by digital cameras. Increase image resolution and dynamic range are examples of such enhancements. Multi-camera systems are the foundation of emerging technologies such as free view point TV. The Panoptic system is a multi-focal omnidirectional camera which has all the attribute...

Small and medium format digital cameras are widely used in Photogrammetric applications due to their accessibility, availability and quick image acquisition and processing. In addition, the resolution of these cameras has significantly increased while their prices decreased. Generally, a small-format digital camera does not have a pre-definition of the internal geometric characteristics, common...

Two types of distortions are produced by the gamma camera. One is nonuniform sensitivity re sponse over the detecting area. The second is spatial distortion; that is, the displacement from their true positions of the xand y-coordinates of a scintilla tion. This component of camera image distortion arises in the resolution and transfer of the xand y-coordinates of a scintillation and results in ...
