In a digital camera system, images are captured using a solid-state image sensor instead of film. As a result, the camera is light, has low power consumption, small dimensions and lower cost. The output of the image sensor is stored in digital memory, typically using solid-state memory ICs or a magnetic hard drive. To view or edit images, stored images can be downloaded to a computer.
Some cameras allow direct connection to a high-quality computer printer.
Other cameras allow direct connection to a television for viewing images. Resolution Measured in pixels. The higher the number of pixels, the better the resolution. Capacity Determined by how much data the camera captures and how densely it packs that data before saving it to onboard memory. Number of images for best quality 2.
