Cameras capture light to create digital images from "summary" of How Technology Works by DK
When you take a photo with a digital camera, you are essentially capturing light. This light is then converted into digital information that creates an image on the camera's sensor. But how does this process work?First, light enters the camera through the lens. The lens focuses the light onto the camera's sensor, which is made up of millions of light-sensitive pixels. These pixels are the building blocks of the image that will be created. As the light hits the sensor, each pixel measures the intensity and color of the light it receives. This information is then converted into digital data, with each pixel assigned a specific color value based on the light it captured. Once all the pixels have recorded their data, it is processed by the camera's software to create a digital image. This image is made up of millions of tiny dots, each representing a pixel and its assigned color value. The final digital image is then stored on the camera's memory card, ready to be viewed on a screen or printed out. The entire process of capturing light, converting it into digital data, and creating an image happens in a fraction of a second when you press the camera's shutter button.- Cameras are sophisticated devices that use the principles of light and technology to create the images we see and share every day. The next time you snap a photo, remember that you are not just capturing a moment, but also capturing light to create a digital image.
