Lag Camera: A Moving Multi-Camera Array for Scene-Acquisition
[article]
2006
Preserved Fulltext
Moreover, since both the lag camera and occluder are moving, the scene behind the occluder is captured by the lag camera even from viewpoints where the occluder lies in between the lag camera and the hidden ...
We describe a class of cameras called lag cameras. The main concept is to generalize a camera to take samples over space and time. ...
A lag camera essentially maps the most difficult case (moving camera and moving scene) to the case of a static camera and a moving scene and enables the use of all algorithms for static cameras. ...

We propose a family of Occlusion-Resistant Camera (ORC) designs for acquiring active environments despite the presence of moving interfering occluders. ...
Our key idea is to capture the scene at least twice from each viewpoint as the camera moves continually to sweep the scene and sample all surfaces. ...
Several automatic methods for video have also been proposed using static camera arrays or a fixed multi-camera sensor [6] . ...

FlatCam is a thin form-factor lensless camera that consists of a coded mask placed on top of a bare, conventional sensor array. ...
Unlike a traditional, lens-based camera where an image of the scene is directly recorded on the sensor pixels, each pixel in FlatCam records a linear combination of light from multiple scene elements. ...
This results in a time-lag between the sensor acquisition and the image display, a timelag that depends on processing time. ...
