digital cameras wikipedia
Can anyone help me with my homework?
For Science Class, I need to write ten facts about a digital camera. Can anyone give me a link to a site or give me some facts about a digital camera? I already searched wikipedia.
digital cameras have a built-in computer
all of them record images electronically
Essentially, a digital image is just a long string of 1s and 0s that represent all the tiny colored dots — or pixels — that collectively make up the image.
With a 3-megapixel camera, you can take a higher-resolution picture than most computer monitors can display.
Instead of film, a digital camera has a sensor that converts light into electrical charges.
The image sensor employed by most digital cameras is a charge coupled device (CCD).
Some cameras use complementary metal oxide semiconductor (CMOS) technology instead.
Both CCD and CMOS image sensors convert light into electrons.
A CCD transports the charge across the chip and reads it at one corner of the array. An analog-to-digital converter (ADC) then turns each pixel’s value into a digital value by measuring the amount of charge at each photosite and converting that measurement to binary form.
CMOS devices use several transistors at each pixel to amplify and move the charge using more traditional wires. The CMOS signal is digital, so it needs no ADC
