  • Publication number: 20240089604
    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.

  • Patent number: 11588984
    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.

  • Patent number: 11443403
    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.

  • Patent number: 11070742
    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.

  • Patent number: 10861127
    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.

  • Patent number: 10863155
    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.

  • Patent number: 10771712
    Abstract: Generating a time-lapse is disclosed. A method includes acquiring, using a camera, a first frame of the time-lapse; acquiring, using the camera, one or more preview images, the preview images are not included in the time-lapse; determining an exposure setting for a second frame of the time-lapse using the one or more preview images; and acquiring, using the camera, the second frame of the time-lapse using the exposure setting. A camera includes a memory and a processor. The processor is configured to execute instructions stored in the memory to acquire a first frame of the time-lapse; acquire one or more preview images, the preview images are not included in the time-lapse; determine an exposure setting for a second frame of the time-lapse using the one or more preview images; and acquire the second frame of the time-lapse using the exposure setting.
