Energy transfer diagram in camera phone?

In a camera phone, energy transfer begins with the conversion of light energy from the scene being captured into electrical energy by the camera's image sensor. This electrical energy is then processed by the phone's internal circuitry, transforming it into digital data. The digital data can be stored as an image file, which can be displayed on the phone's screen, converting electrical signals back into light energy for visual representation. Additionally, the battery provides chemical energy to power the entire device throughout this process.
