Digital camera and analog camera difference
1, analog camera: it belongs to the front-end video capture device, analog camera output is the analog video signal, through the encoder can be video capture equipment to produce analog video signals into digital signals, and then stored in the computer. The video signal captured by the analog camera must be converted to digital mode via a specific video capture card and compressed before it can be converted to a computer.
2, digital camera: refers to the camera image processing and signal recording all use digital signal to complete the camera. The biggest feature of such a camera is that the signal recorded on the tape is a digital signal, not an analog signal. Digital camera into the image signal by the CCD into electrical signals, immediately by the circuit digital, and then all the records before the processing of all digital processing, and finally processed the digital signal directly to the tape or memory card.
The analog camera can convert the analog video signal generated by the video capture device into a digital signal and store it in a computer. The video signal captured by the analog camera must be converted to digital mode via a specific video capture card and compressed before it can be converted to a computer. Digital camera can capture images directly, and then through the string, parallel port or USB interface to the computer.
