TL;DR: A unique array of 100 custom video cameras that are built are described, and their experiences using this array in a range of imaging applications are summarized.
Abstract: The advent of inexpensive digital image sensors and the ability to create photographs that combine information from a number of sensed images are changing the way we think about photography. In this paper, we describe a unique array of 100 custom video cameras that we have built, and we summarize our experiences using this array in a range of imaging applications. Our goal was to explore the capabilities of a system that would be inexpensive to produce in the future. With this in mind, we used simple cameras, lenses, and mountings, and we assumed that processing large numbers of images would eventually be easy and cheap. The applications we have explored include approximating a conventional single center of projection video camera with high performance along one or more axes, such as resolution, dynamic range, frame rate, and/or large aperture, and using multiple cameras to approximate a video camera with a large synthetic aperture. This permits us to capture a video light field, to which we can apply spatiotemporal view interpolation algorithms in order to digitally simulate time dilation and camera motion. It also permits us to create video sequences using custom non-uniform synthetic apertures.

TL;DR: A new camera with a hemispherical field of view is presented and results are presented on the software generation of pure perspective images from an omnidirectional image, given any user-selected viewing direction and magnification.
Abstract: Conventional video cameras have limited fields of view that make them restrictive in a variety of vision applications. There are several ways to enhance the field of view of an imaging system. However, the entire imaging system must have a single effective viewpoint to enable the generation of pure perspective images from a sensed image. A new camera with a hemispherical field of view is presented. Two such cameras can be placed back-to-back, without violating the single viewpoint constraint, to arrive at a truly omnidirectional sensor. Results are presented on the software generation of pure perspective images from an omnidirectional image, given any user-selected viewing direction and magnification. The paper concludes with a discussion on the spatial resolution of the proposed camera.

TL;DR: In this paper, an in vivo video camera system and an autonomous video endoscope are described, each system includes a swallowable capsule (10), a transmitter (28) and a reception system (12).
Abstract: An in vivo video camera system and an autonomous video endoscope are described. Each system includes a swallowable capsule (10), a transmitter (28) and a reception system (12). The swallowable capsule (10) includes a camera system (24) and an optical system (26) for imaging an area of interest onto the camera system (24). The transmitter (28) transmits the video output of the camera system (24) and the reception system (12) receives the transmitted video output.

TL;DR: This paper reviews the application of analytical self-calibration to digital cameras and an overview is given of each of the four main sources of departures from collinearity in CCD cameras.
Abstract: Over the 25 years since the introduction of analytical camera self-calibration there has been a revolution in close-range photogrammetric image acquisition systems. High-resolution, large-area ‘digital’ CCD sensors have all but replaced film cameras. Throughout the period of this transition, self-calibration models have remained essentially unchanged. This paper reviews the application of analytical self-calibration to digital cameras. Computer vision perspectives are touched upon, the quality of self-calibration is discussed, and an overview is given of each of the four main sources of departures from collinearity in CCD cameras. Practical issues are also addressed and experimental results are used to highlight important characteristics of digital camera self-calibration.

TL;DR: A novel scheme for data reception in a mobile phone using visible light communications (VLC) is proposed, exploiting the rolling shutter effect of CMOS sensors, and a data rate much higher than the camera frame rate is achieved.
Abstract: In this paper, a novel scheme for data reception in a mobile phone using visible light communications (VLC) is proposed. The camera of the smartphone is used as a receiver in order to capture the continuous changes in state (on-off) of the light, which are invisible to the human eye. The information is captured in the camera in the form of light and dark bands which are then decoded by the smartphone and the received message is displayed. By exploiting the rolling shutter effect of CMOS sensors, a data rate much higher than the camera frame rate is achieved.
