Digital cameras work by capturing light through a lens and converting it into an electronic image that can be stored and viewed on a screen or printed.
When light enters the camera through the lens, it passes through a series of optical elements that focus the light onto a sensor called a CCD (Charge-Coupled Device) or CMOS (Complementary Metal-Oxide-Semiconductor). This sensor is made up of millions of tiny light-sensitive pixels that convert the incoming light into electrical signals.
Once the light has been converted into electrical signals, these signals are processed by the camera's image processor. The image processor then processes the signals, adjusting for factors such as exposure, white balance, and color saturation.
The processed image is then saved onto a memory card in a digital file format, such as JPEG or RAW. This digital file can then be viewed on the camera's LCD screen, transferred to a computer for editing, or printed out as a physical image.
Overall, digital cameras work by combining optics, electronics, and digital processing to capture and store images in a convenient and portable format.
