Digital Camera Image Processing

Abstract

DefinitionDigital imaging devices, such as digital camera, contain built-in image processing systems for applications such as computer vision, and multimedia and surveillance.IntroductionDigital imaging solutions are becoming increasingly important due to the development and proliferation of imaging-enabled consumer electronic devices, such as digital cameras, mobile phones, and personal digital assistants [1–3]. Because its performance, flexibility, and reasonable expenses digital imaging devices are used extensively in applications ranging from computer vision, multimedia, sensor networks, surveillance, automotive apparatus, to astronomy.Information about the visual scene is acquired by the camera by first focusing and transmitting the light through the optical system, and then sampling the visual information using an image sensor and an analog-to-digital (A/D) converter. Typically, zoom and focus motors control the focal position of the lens. Optical aliasing f ...
