Main parameters measured by camera

Resolution (pixel resolution) is one of the most common parameters. The resolution is mainly determined by the image sensor. The higher the resolution, the finer the image and the better the effect, but the image takes up more storage space. Generally speaking, the camera pixel is the largest pixel in camera mode, and the pixel in camera (video shooting) is usually smaller. For example, the N97 camera has 500W pixels, but the maximum resolution in camera mode is only 640 x480.

principle of operation

CPU integrates video processing system and camera driver. There are 8- 10 data signals between the CPU and the camera, depending on the CPU model and the camera itself. When the mobile phone system enters the photographing or shooting state, the power supply provides a voltage of 2.8V, and the reset signal sent by the CPU resets the camera and starts to transmit data, so that the camera enters the working state.
