    Abstract: System and method can support an image processing device. The image processing device operates to obtain a first set of characterization values, which represents a first group of pixels that are associated with a denoising pixel in an image. Also, the image processing device can obtain a second set of characterization values, which represents a second group of pixels that are associated with a denoising reference pixel. Furthermore, the image processing device operates to use the first set of characterization values and the second set of characterization values to determine a similarity between the denoising pixel and the denoising reference pixel. Then, the image processing device can calculate a denoised value for the denoising pixel based on the determined similarity between the denoising pixel and the denoising reference pixel.

    Abstract: A system for automatic focusing with a lens and methods for making and use the same are provided. When performing a focusing operation, a controller calculates a focus measure value for each lens position of a plurality of lens positions. The focus measure values are calculated based on each of the window evaluation values and a respective weight for image focusing windows within a set of image focusing windows. The controller then compares the calculated focus measure values of the plurality of lens positions in order to select an optimal lens position. The set of image focusing windows can be selected based on one or more sets of image focusing window selection rules derived from statistical data. In addition, the respective weights for image focusing windows can also be calculated based on the statistical data.

    Abstract translation: 提供了一种用于自动聚焦透镜的系统及其制造和使用方法。 当进行聚焦操作时，控制器计算多个透镜位置的每个透镜位置的焦点测量值。 基于每个窗口评估值和一组图像聚焦窗口内的图像聚焦窗口的相应权重来计算焦点测量值。 控制器然后比较所计算的多个透镜位置的焦点测量值，以便选择最佳的透镜位置。 可以基于从统计数据导出的一组或多组图像聚焦窗口选择规则来选择该组图像聚焦窗口。 此外，还可以基于统计数据来计算图像聚焦窗口的相应权重。

    Abstract: Image processing method, drone, and drone-camera system are provided. The method includes acquiring, according to a current environmental parameter of the drone, a target sky image that matches the current environmental parameter; and determining a direction parameter of the camera device when capturing a to-be-stitched image. The to-be-stitched image is an image captured under the current environmental parameter. The method further includes stitching the target sky image with the to-be-stitched image according to the direction parameter to obtain a panoramic image.

    Abstract: An imaging system includes a first optical module including a first image sensor, a second optical module comprising a second image sensor, and an image processor. The first optical module has a first focal length range. The second optical module has a second focal length range. The first focal length range and the second focal length range are different. The image processor is configured to receive image data for a first image from the first optical module and/or image data for a second image from the second optical module and generate data to show the first image and/or the second image within a display.

    Abstract: An unmanned aerial vehicle (UAV) with audio filtering components includes a background noise-producing component, a background microphone, and a noise emitter. The background noise-producing component is configured to produce a background noise. The background microphone is positioned within a proximity sufficiently close to collect interfering noise from the background noise producing component. The background microphone is configured to collect audio data including the background noise. The noise emitter is disposed within a proximity sufficiently close to the background noise-producing component to reduce the interfering noise. The noise emitter is configured to emit an audio signal having a reverse phase of the audio data collected by the background microphone.
