Sony cameras suggest that cameras can't use this battery. What happened?

It's broken. I suggest a new battery. At present, there are some cracked batteries of different brands on the market, but based on Sony's stable model, it is recommended to buy original batteries to replace them.

There are many kinds of cameras and waterproof digital cameras, and the basic principle is the same: converting optical image signals into electrical signals for storage or transmission. When we shoot an object, the light reflected by the object is collected by the camera lens and focused on the light receiving surface of the camera device (such as the target surface of the camera tube), and then the light is converted into electric energy by the camera device, that is, the "video signal" is obtained.

The photoelectric signal is very weak, so it needs to be amplified by pre-amplifier circuit and then processed and adjusted by various circuits. The final standard signal can be sent to video recorders and other recording media for recording, or spread through a propagation system, or sent to a monitor for display.

Image decomposition and photoelectric signal conversion device. Image decomposition is the process of decomposing a complete image into several independent pixels (the smallest unit of TV image). Generally speaking, the more pixels, the clearer the image. Each pixel is represented by a single color and brightness. The camera can convert the optical signal of each pixel in the image into a corresponding electrical signal, and then transmit it to the output terminal in a certain order. Camera devices are divided into camera tubes and solid-state (semiconductor) camera devices.
