The present disclosure relates to a brightness adjustment method and device, and a storage medium. The method can include detecting a brightness of an environment where a mobile terminal is located to acquire a brightness value. When a decrease of the brightness value acquired at a present moment relative to the brightness value acquired at a previous moment reaches a first preset value, a radar wave is transmitted, and an echo of the radar wave is detected. The method determines whether there is an occlusion causing the decrease of the acquired brightness value according to a transmitting parameter of the radar wave and an echo parameter of the echo. When there is no occlusion, display brightness of the mobile terminal is adjusted according to the brightness value acquired at the present moment. When the occlusion is present, the display brightness of the mobile terminal at the present moment is maintained.

A display apparatus includes at least one memory and at least one processor which function as a processing unit, a display control unit, and a setting unit. The processing unit is configured to perform first image processing and second image processing. The display control unit is configured to perform control to perform a first display based on a result of the first image processing and a second display based on a result of the second image processing, together. The setting unit is configured to set upper-limit brightness of the second display. An Electro-Optical Transfer Function (EOTF) type of the first display and an EOTF type of the second display are EOTF types dealing with high dynamic range (HDR). The processing unit converts brightness of an image according to the upper-limit brightness and the EOTF type of the first display in the second image processing.

After the parameters are applied to the circuit system, the circuit system operates the display device using the parameters. The data generated by the circuit system can be adjusted for matching new parameters. Afterwards, when the new parameters are applied to the circuit system, video and audio are outputted according to the matched parameters, and the camera and microphone in the panel module are also operated according to the matched parameters.
