- Digital Camera
- Use a grid of tiny light sensors to measure the amount of light passing through the lens when the shutters are open.
- Each sensor measures the colour and brightness of the each pixel.
- Each sensor turns the light into electricity and the amount of charge is stored as binary data.
- The binary data is recorded onto the memory card
- CCD (Couple-charged device)
- Transports the charge across the chip and reads it at one corner of the array.
- CMOS (Complementary metal-oxide semiconductor)
- Uses several transistors at each pixel to amplify and move the charge using more traditional wires.
- Two types of sensors: CCD and CMOS. CCD higher quality but more power
- Use a grid of tiny light sensors to measure the amount of light passing through the lens when the shutters are open.
