An Introduction to Digital Cameras
Regional Anesthesia and Pain Medicine, 2001People in all walks of life are using digital cameras instead of the traditional film cameras. Reasons include simplicity of use, ease of development, ability to incorporate the pictures into documents, potential to edit the pictures easily, and capability to send them by e-mail.

MEMS technology uses photolithography and etching of silicon wafers to enable mechanical structures with less than 1 mm tolerance, important for the miniaturization of imaging systems. In this paper, we present the first silicon MEMS digital auto-focus camera for use in cell phones with a focus range of 10 cm to infinity.

A Comparison of Digital Cameras
Facial Plastic Surgery, 1999Digital photography is becoming an increasingly popular alternative to traditional 35-mm photography. Clearly, the efficiency and versatility of digital cameras will have a major impact on the future of clinical photodocumentation in facial plastic surgery.

IEEE Transactions on Consumer Electronics, 1999
This paper presents an interpolation method for digital still cameras (DSCs) which is based on color signal correlation. The authors have developed a method of reducing aliasing by increasing the resolution of color signals in DSCs that use a single-plate charge coupled device (CCD) with a primary color filter array. The new method interpolates signals

The quality of digital cameras has undergone a magnificent development during the last 10 years. So have the methods to evaluate the quality of these cameras. At the time the first consumer digital cameras were released in 1996, the first ISO standards on test procedures were already on their way.

Cameras for Digital Microscopy
2003This chapter reviews the fundamental characteristics of charge-coupled devices (CCDs) and related detectors, outlines the relevant parameters for their use in microscopy, and considers promising recent developments in the technology of detectors. Electronic imaging with a CCD involves three stages--interaction of a photon with the photosensitive ...

Distortion correction for digital cameras
Proceedings SIBGRAPI'98. International Symposium on Computer Graphics, Image Processing, and Vision (Cat. No.98EX237), 2002This paper describes a method to correct lens distortion for digital cameras. A simple but effective distortion model using local spatial transformation will be used. In addition, the effect of effective focal length on the distortion model will be considered, and we will discuss how to introduce this factor to enhance the model.
