Experiment Study of a digital camera

A digital camera is a photographic device which captures light on an electronic type medium, rather than on film, and which converts the information received by this medium to encode it digitally. A digital camera uses a CCD or CMOS sensor to acquire images, and saves them on memory cards.

Subjects discussed :
- Sharpness, focus
- Magnification, magnification
- Aperture, exposure time and ISO
- Depth of field measurement
- Resolution, circle of confusion
- Synthesis of a color image

Principles and objectives:
The aim of this practical work is to present the operation of a digital camera and to analyze the shooting parameters (focus, aperture and exposure time), the parameters of the complete system (angle of view, magnification, depth of field and magnification), parameters relating to the sensor (sensitivity and resolution) as well as the study of the digital image obtained.
