Abstract: Methods and systems are provided for video processing. Video may be captured using an image capture device at a first definition. The image capture device may optionally be, or may be on board, an aerial vehicle, such as an unmanned aerial vehicle. A first set of video data may be transmitted to a user terminal at a second definition, which may be less than the first definition. A user may interact with the user terminal to edit the video and generate a video edit request. The video edit request may be transmitted to the image capture device, which may accordingly produce a second set of video data in accordance with the video edit request, at a third definition. The third definition may be greater than the second definition.

Abstract: The present invention provides a method and apparatus for generating a high dynamic range image (HDRI). After acquiring a first illuminance diagram, a base layer and detail layers are extracted from the first illuminance diagram, where the base layer contains low frequency information of the first illuminance diagram and the detail layers contain high frequency information of the first illuminance diagram. The dynamic range of the base layer is then compressed while dynamic ranges of the detail layers remain uncompressed. Further, a second illuminance diagram is generated from the first illuminance diagram by fusing the base layer with the compressed dynamic range and the detail layers, the second illuminance diagram is mapped onto a plurality of preset color channels; and the images on the plurality of preset color channels are fused into the HDRI. Therefore, the detail information in the original illuminance diagram can be preserved.

Abstract: A method for adjusting a storage bitrate of a data buffer with a buffer size includes: storing data at a selected storage bitrate into the data buffer; writing the stored data from the data buffer into a storage device attached to the data buffer with a predetermined writing speed; monitoring a data amount of the stored data in the data buffer; monitoring a trend of change in the data amount; determining whether the data amount has reached a first ascending threshold, the first ascending threshold being below the buffer size of the data buffer; and in response to the data amount reaching the first ascending threshold and the trend of change in the data amount being an ascending change, reducing the storage bitrate in the data buffer.

Abstract: A method for generating a high dynamic range image (HDRI) includes acquiring a first illuminance diagram, generating a second illuminance diagram from the first illuminance diagram by modifying a dynamic range of at least a portion of the first illuminance diagram, and generating the HDRI based on the second illumination diagram. The first illuminance diagram is obtained based on a camera response function and an illuminance logarithm obtained based on a plurality of images having different exposure conditions.

Abstract: A method of processing a video includes capturing a first set of video data at a first definition, transmitting the first set of video data at a second definition lower than the first definition wirelessly to a user terminal, receiving a video edit request wirelessly from the user terminal, and finding video corresponding to edited video data described by the video edit request, thereby forming a second set of video data at a third definition. The video edit request is formed from editing the received first set of video data at the second definition at the user terminal.

Abstract: A system for adapting various writing speeds of storage devices and methods for making and using same are provided. A recording device maintains a data buffer with a buffer size. Data recorded by the recording device with a selected recording bitrate is stored into the data buffer of the recording device. The recorded data is written from the data buffer into a selected storage device that is attached onto the recording device. An amount of recorded data stored in the data buffer is compared with two or more sets of thresholds, and the recording bitrate of the recording device can be adjusted, as needed, in response to the results of the comparison. By adjusting the recording bitrate, the recording device advantageously can accommodate storage devices with various speeds while maintaining the quality of the recorded data and maximizing the capacity of the storage device.
