Abstract
The present disclosure provides a flash assembly of a mobile terminal, the flash assembly is a display assembly, and the display assembly disposed at a front end of a camera assembly of the mobile terminal and connects to a processor of the mobile terminal via an I2C. The present disclosure also provides a control system, comprising a scene predictor, a controller and a flash assembly. A control method is also provided. Compared with the related art, the protective cover of the camera is replaced by a display assembly, thereby reducing the number of components; and the display assembly can reduce the thermal output.
Claims20
A control system for a flash assembly of a mobile terminal, comprising:
- a flash assembly disposed on the mobile terminal, the flash assembly being a display assembly disposed at a front end of a camera assembly of the mobile terminal;
- a scene predictor configured to acquire an ambient light color temperature and an ambient light brightness of a current scene through the camera assembly, calculate a focus point, a target value for color temperature adjustment and a target value for brightness adjustment using 3A algorithm, and transmit the focus point, the target value for color temperature adjustment and the target value for brightness adjustment to a controller;
- the controller configured to calculate correspondingly a shutter speed, a sensitivity of a sensor of the camera assembly, and a current ratio outputted by the flash assembly according to the target value for color temperature adjustment and the target value for brightness adjustment;
- the flash assembly outputting a corresponding display brightness and a corresponding display color temperature according to the current ratio;
- and
- a manual regulator configured to adjust parameters of brightness, color temperature, and flash frequency of the flash assembly manually and transmit the parameters to the controller, the controller outputting a corresponding current ratio according to the parameters;
- or the manual regulator configured to adjust the color of the flash assembly.
A flash assembly of a mobile terminal, wherein the flash assembly disposed on the mobile terminal, the flash assembly is a display assembly and is disposed at a front end of a camera assembly of the mobile terminal and connects to a processor of the mobile terminal via an I2C.
A control method of a flash assembly, comprising:
- a scene predictor prejudging an ambient light color temperature and an ambient light brightness of a current scene to obtain data of the same, calculating a focus point, a target value for color temperature adjustment and a target value for brightness adjustment using 3A algorithm, and transmitting the focus point, the target value for color temperature adjustment and the target value for brightness adjustment to a controller;
- the controller calculating correspondingly a shutter speed, a sensitivity of a sensor of the camera assembly, and a current ratio outputted by the flash assembly according to the target value for color temperature adjustment and the target value for brightness adjustment;
- and
- the flash assembly outputting correspondingly a display color temperature and a display brightness.
