  • Patent number: 11463605
    Abstract: Systems and methods of the invention merge information from multiple image sensors to provide a high dynamic range (HDR) video. The present invention provides for real-time HDR video production using multiple sensors and pipeline processing techniques. According to the invention, multiple sensors with different exposures each produces an ordered stream of frame-independent pixel values. The pixel values are streamed through a pipeline on a processing device. The pipeline includes a kernel operation that identifies saturated ones of the pixel values. The streams of pixel values are merged to produce an HDR video.

  • Patent number: 11394895
    Abstract: A system, method, and computer program product for generating a digital image. The method comprises receiving a shutter release command and causing a camera module to sample a first image of a photographic scene based on a first set of sampling parameters in response to the shutter release command. Next, the first image within an image set is stored and a camera module is caused to sample a second image of the photographic scene based on a second set of sampling parameters in response to the shutter release command. Additionally, the second image within the image set is stored, and a strobe intensity value is specified based on a measured exposure for images in the image set. Lastly, a strobe unit is configured based on the strobe intensity value, and in response to configuring the strobe unit, the camera module is caused to sample a final image.

  • Patent number: 10523869
    Abstract: A camera shake detection unit detects a camera shake value. A shutter button that is a shutter operating unit is operated in imaging. A prediction range calculation unit calculates a prediction range of a camera shake value that occurs in a case where the shutter button is operated, on the basis of a history of the camera shake value after a previous operation of the shutter button. A camera shake display controller displays a locus of camera shake on an EVFLCD on the basis of the camera shake value detected by the camera shake detection unit before the operation of the shutter button, and displays the prediction range on the EVFLCD using a leading end of the locus as a starting point.
