Did you know about your images sensor?(CCD)

Did you know about your images sensor?.Do you have a camera?.Theres two kind of images sensor that used on camera that usually used,they are CMOS and CCD.Whats that? and how theys work?,let me explain.
An image sensor is a device that converts an optical image into an electronic signal. It is used mostly in digital cameras, camera modules and other imaging devices.A CCD image sensor is an analog device. When light strikes the chip it is held as a small electrical charge in each photo sensor. The charges are converted to voltage one pixel at a time as they are read from the chip. Additional circuitry in the camera converts the voltage into digital information.
The advantages of this sensor are :
1. Mature technology 
2. Simple sensor design (cheaper)
3. High sensitivity (including dynamic range)
4. Each pixel has the same performance (uniform)
 The disvantages of this sensor are :
1. Overall system design (CCD plus ADC) to be more complicated and wasteful power
2. Overall processing speed is slower than CMOS
3. Sensitive to smearing or blooming (leaking pixels) while capturing the light brighter
This is how ccd works :
