Abstract: A system for adjusting an optical path length includes: a camera body; an image sensor coupled to the camera body; a first optical device coupled to the camera body; and a second optical device coupled to the camera body. At least one of the first and the second optical devices are movable relative to the camera body. The optical path length between the image sensor and the camera body opening is continuously adjusted by movement of the at least one of the first and the second optical devices relative to the image sensor. As the at least one of the first and the second optical devices move relative to the image sensor, the first optical device is in continuous contact with the second optical device.

Abstract: A method includes obtaining a dynamic range representation of an image including multiple color channels. The dynamic range representation includes dynamic range information of pixels of the image in the color channels. The method further includes decomposing the dynamic range representation into a smooth portion, a color portion, and a detail portion. The smooth portion includes low frequency information of the pixels in the color channels. The color portion includes color intensity information of the pixels in the color channels. The detail portion includes high frequency information of the pixels in the color channels. The method also includes adjusting the smooth portion, the color portion, and the detail portion, respectively, to obtain an adjusted smooth portion, an adjusted color portion, and an adjusted detail portion, and combining the adjusted smooth portion, the adjusted color portion, and the adjusted detail portion to generate an output image.

Abstract: A system for focusing an imaging device according to a focal distance setting and methods for making and using same. The focal distance setting can be an infinite focal distance setting for objects that are far away from the imaging device. Focusing of the imaging device can be triggered by activation of a button for “one-touch” rapid focusing. The focusing, for example, can be triggered at a terminal that is distal from the imaging device through an app and suitable user interface. The focal distance setting can be determined by interaction via the app, which can present a prompt to direct the imaging device to an object at a suitable distance. Once determined, the focal distance setting can be stored and later retrieved for rapid focusing. The present system and methods advantageously can be used aboard a mobile platform such as an unmanned aerial vehicle.

Abstract: An imaging system for adaptively generating panoramic images and methods for manufacturing and using same are provided. The system includes an imaging device configured to capture digital images at a plurality of image capture positions. The system further includes a processor configured to identify an overlapping portion of first and second images captured at respective first and second image capture positions, determine a stitching position quality measure for a plurality of stitching positions in the overlapping portion of the first and second images, and select a stitching position based on the determined stitching position quality measures of the plurality of stitching positions of the first and second images. The processor is also configured to stitch the first and second images together at the selected stitching position to generate a panoramic image and determine a third image capture position based on the stitching position quality measure.

Abstract: Systems and methods can support a data processing apparatus. The data processing apparatus can include a data processor that is associated with a data capturing device on a stationary object and/or a movable object. The data processor can receive data in a data flow from one or more data sources, wherein the data flow is configured based on a time sequence. Then, the data processor can receive a control signal, which is associated with a first timestamp, wherein the first timestamp indicates a first time. Furthermore, the data processor can determine a first data segment by applying the first timestamp on the data flow, wherein the first data segment is associated with a time period in the time sequence that includes the first time.

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.
