Abstract: Embodiments of the present invention are an image processing method, a photographing device, and a storage medium. The method includes: acquiring an image according to a first resolution and processing the image in a first processing method in a real-time preview state, switching to a photographing state, acquiring an image according to a second resolution and processing the image in a second processing method in the photographing state, and then switching from the photographing state to the real-time preview state. In this way, in a process of switching between the two working states, the image can be processed in a corresponding state without restarting an ISP or re-importing a parameter. Compared with a method of switching different working states by powering on and off the ISP in the prior art, the method provided in the present application can achieve faster dynamic switching between different working states.

Abstract: The present invention relates to a data transmission control method, an information sending end and receiving end, and an aerial vehicle image transmission system. The data transmission control method includes: receiving data frames sent by a sending end, the data frames being sequentially sent by the sending end in an order of a data frame sequence; and returning an acknowledgement signal corresponding to a currently-received data frame N to the sending end, to enable the information sending end to determine a current network status according to the acknowledgement signal, and adjusting data encoding quality of the sent data frame based on the current network status. In the method, delays for image quality and transmission speed to recover when a network status recovers can be effectively reduced by rapidly determining a current network status based on the feedback of an acknowledgement signal.

Abstract: Embodiments are a high-dynamic-range (HDR) image automatic exposure method and an unmanned aerial vehicle (UAV). The HDR image automatic exposure method is applicable to a UAV and includes: obtaining statistical information and a window weight of automatic exposure; obtaining an evaluation value of the automatic exposure according to the statistical information and the window weight that are obtained; obtaining a compensation amount of the automatic exposure according to the evaluation value and an obtained automatic exposure target value; and triggering the automatic exposure when the compensation amount meets a preset trigger condition. Therefore, problems such as inaccurate brightness and darkness and oscillation during automatic exposure can be finally avoided.

Abstract: Embodiments of the present invention discloses an imaging calibration method and apparatus for a dual-light camera and a dual-light camera. A thermal imaging image including a first calibration frame image and a visible light image including a second calibration frame image are acquired. The first calibration frame image and the second calibration frame image are images of a same calibration frame respectively photographed by a thermal imaging camera and a visible light camera. First position information of the first calibration frame image in the thermal imaging image and second position information of the second calibration frame in the visible light image are acquired. Calibration parameters are generated according to the first position information and the second position information. A position of the thermal imaging image synthesized in the visible light image in the visible light image is adjusted according to the calibration parameters.
