OV-5647: Raspberry Pi Camera
Quickstart:
Introduction:
The OV-5647 Raspberry Pi Camera Module is a compact and versatile digital imaging device designed to work seamlessly with the Raspberry Pi platform. It captures images by detecting light intensity and frequency across a two-dimensional sensor grid, operating on the foundational pinhole camera model principle. This model focuses light through a lens to create an inverted image, which is then corrected when displayed as digital pixels. The camera's adjustable focal length allows for clear image capture of objects at varying distances, making it suitable for a range of applications. It is most commonly used in photography, computer vision projects, and for educational purposes, providing a practical tool for both hobbyists and professionals in exploring digital imaging and vision applications.

Working Principle:
Digital cameras work by detecting light intensity and frequency over a 2D grid. A lens focuses light from a single point, which creates an inverted image when these values are registered on the sensor grid. The image captured is then re-inverted to correct for this when converted to pixels on a screen. You now have a digital photograph. This is the pinhole camera model, and it forms the basic theory for of nearly all modern photography and computer vision applications.
Modern cameras lenses can have their focal length changed to create a clear image for objects at different distances.
