Abstract: Multiple images that include a first image, a second image, and a third image are received. The multiple images are such that the second image is temporally between the first image and the third image. The first image, the second image, and the third image are combined to obtain a long-exposure image. High dynamic range processing is applied to the second image and the long-exposure image to obtain an output image with a larger dynamic range than a dynamic range of the second image. The high dynamic range processing uses the second image as a short-exposure image. An image based on the output image is transmitted, stored, or displayed.

Abstract: An image capture device may detect and repair banding artifacts in a video. The image capture device may include an image sensor and an image processor. The image sensor may capture a frame that includes a sinusoidal light waveform banding artifact. The image processor may detect a sinusoidal light waveform in the frame. The image processor may perform a sinusoidal regression. The image processor may obtain an inverted gain map. The image processor may apply the inverted gain map to the frame. The image processor may output the frame.

Abstract: A method for reducing overexposure or underexposure in a time-lapse includes acquiring, using an image capture device, a first frame of the time-lapse using a first exposure setting; and acquiring, using the image capture device, a second frame of the time-lapse. The first frame of the time-lapse is acquired under a first luminance condition. The second frame of the time-lapse is acquired under a second luminance condition that is different from the first luminance condition. The second frame of the time-lapse is acquired using an exposure setting that is determined based on respective exposure settings of one or more preview images obtained between the first frame of the time-lapse and the second frame of the time-lapse. The one or more preview images are not included in the time-lapse.

Abstract: Multiple pipelines are used for image and video processing. In a first image processing pipeline, an image is retrieved from a buffer and processed using one or more image processing units. An altered image produced using the first image processing pipeline replaces the earlier version of the image stored in the buffer. The altered image may also be immediately output for display or encoding. In the second image processing pipeline, the altered image is retrieved from the buffer and processed according to image processing control statistics collected at the first image processing pipeline. The resulting processed image may then be encoded. A processed image output from the second image processing pipeline has a higher resolution than the altered image output from the first image processing pipeline.

Abstract: Adaptive acquisition control timing control for image and video acquisition and processing includes obtaining, by an auto-exposure compensation component of an image processing pipeline of an image capture apparatus, during a current sensor readout window corresponding to obtaining current input image data from an image sensor of the image capture apparatus, in accordance with defined image acquisition and processing timing data, current auto-exposure compensation data for processing subsequent input image data obtained from the image sensor during a subsequent sensor readout window sequentially immediately subsequent to the current sensor readout window, and outputting, to a second data storage unit instance of the image processing pipeline, by the auto-exposure compensation component, during the current sensor readout window, the current auto-exposure compensation data.

Abstract: A method for reducing overexposure or underexposure in a time-lapse includes acquiring, using an image capture device, a first frame of the time-lapse using a first exposure setting; and acquiring, using the image capture device, a second frame of the time-lapse. The first frame of the time-lapse is acquired under a first luminance condition. The second frame of the time-lapse is acquired under a second luminance condition that is different from the first luminance condition. The second frame of the time-lapse is acquired using an exposure setting that is determined based on respective exposure settings of one or more preview images obtained between the first frame of the time-lapse and the second frame of the time-lapse. The one or more preview images are not included in the time-lapse.

Abstract: An image captured using an image sensor is processed to determine control statistics and to produce an altered image which can be output for display or further processing at an image capture device, and the image is then processed according to the control statistics to produce a processed image which can be output for display or further processing at the image capture device or at another device. The altered image may have a lower resolution than the processed image. The image may be stored in a buffer. For example, the image may be retrieved from the buffer to produce the altered image, and again retrieved from the buffer to produce the processed image. The altered image may replace the image within the buffer. For example, the processed image may be produced to represent the altered image at a higher resolution.

Abstract: A processor of a camera for capturing a time-lapse is configured to acquire a first frame of the time-lapse; calculate an exposure setting for a second frame of the time-lapse; and acquire the second frame of the time-lapse using the exposure setting. The exposure setting prevents a flickering effect in the time-lapse. The exposure setting is determined using one or more preview images that are previewed in a time gap between the first frame and the second frame.
