How Does My Digital Camera Work?
The introduction of digital cameras marked a landmark in the development of photography. Digital cameras are extremely different from traditional film based cameras. Film based cameras relied on the simple method of exposing a photosensitive chemical known as camera film to a scene which creates an imprinted image also known as negative.
Digital cameras are far more advanced and use CCD (Charge-Coupled Device). CCD is an electronic device that creates an electric charge when the photons strike against a photosensitive material. This phenomenon is knows as photoelectric effect.
Digital cameras are equipped with ‘chips’, these chips can be CCD, CMOS (Complementary Metal Oxide Semiconductor), foveon or others. These chips replace the films used in older cameras. The digital cameras also have a smart digital sensor which has ‘pixels’ laid across it. Just to give an insight into the resolution power of these sensors, a sensor with 3702x2704 pixels will have over 10 million pixels giving the camera a rating of 10 ‘Megapixels’.
Megapixels can be deemed as the number of dots that each image is made up of. The Megapixels power of digital camera is directly proportional to the sharpness of images. Now when the light rays from a light source strikes against these megapixels, they get excited leaving an imprint behind. After this the imprinted image is made to pass through color filters which converts the image from light signals into electric analog signals. The analog signal is then finally run through an analog to digital converter which produces the final digital image.
The produced images are then compressed and saved onto the memory chips. Digital cameras have many benefits including;
1. Providing the user to review the images right after taking them.
2. Easy transfer to computer and other devices.
3. Big memory to ensure that you never run out of space.
4. Portability and good ergonomics.
Because of this, it looks like digital cameras are here to stay.
