How your phone turns light into a digital memory
In short: From the human eye to the smartphone in your pocket, cameras rely on a fundamental process of capturing light. This video explains the mechanics of how light is transformed into the pixels that make up your digital photos.
The process begins with light entering the camera lens, which focuses the image onto a sensor. This sensor is composed of millions of individual pixels, which act as light-sensitive components. These components convert the energy from the visible spectrum into electrical signals.
Modern cameras primarily use CMOS or CCD image sensors. These sensors utilize photodiodes—devices that generate an electric current when struck by photons. By measuring the intensity of light hitting each pixel, the camera can reconstruct a visual image, mimicking the way the human eye perceives the world.
