  • Patent number: 10999506
    Abstract: Described are systems, methods, and apparatus for generating motion extracted images having a high dynamic range (“HDR”) based on image data obtained from one or more image sensors at different times. The implementations described herein may be used with a single image sensor or camera that obtains images at different exposures sequentially in time. The images may be processed to detect an object moving within the field of view and pixel information corresponding to that moving object extracted. The non-extracted image data may then be combined to produce a motion extracted HDR image that is substantially devoid of the moving object.

    Abstract: The invention disclosed herein concerns a privacy enhancing device for use with IP cameras and related methods. The privacy device includes an adjustable light filter and is configured to be placed over the lens of an IP camera such that the image captured by the IP camera passes through the filter. The transparency of the light filter is controlled using a control module in response to user inputs received using an on-board user interface so as to provide varying levels of privacy ranging from an opaque state and a transparent state. Inputs that serve to facilitate and enhance operation of the device can also be received from other input sources such as connected computing devices. For security, the control path defined by the control module and the on-board user input device can be isolated from other more sophisticated control devices that can be prone to hacking and remote control.

    Abstract: Provided is a device and a method in which an HDR image of which a setting luminance is higher than the highest allowable luminance of a display unit, can be displayed as a bright image in a bright audiovisual environment. An adjusted luminance for output is calculated by multiplying an output luminance calculated according to an input/output transfer function corresponding to an input HDR image, and a predetermined gain, together, and thus, a display image is generated. An image signal processing unit sets a reference point P to be in a position based on the highest allowable luminance of a display unit, and calculates the adjusted luminance for output by applying a gain function of setting a gain, based on the reference point P, to an input/output transfer function according to the input HDR image, and thus, generates the display image.

  • Patent number: 10498970
    Abstract: “Programmed manual modes” mimic the processes a digital camera user goes through manually, but at the speed of the processor built in the camera. Each program preferably includes an exposure condition and a set of exposure parameters, with each exposure parameter having a plurality of exposure settings and a plurality of exposure setting priorities. The processor automatically applies an exposure value from each exposure setting and determines if the exposure condition is met. If the exposure condition is met, the processor captures and stores the image. If not, the processor applies a different exposure value and determines if the exposure condition is met based on the different exposure value.

  • Patent number: 10498971
    Abstract: Aspects of the present disclosure relate to systems and methods for generating High-Dynamic Range (HDR) images. An example device may include a camera, one or more processors, and a memory. The memory may include instructions that, when executed by the one or more processors, cause the device to determine, from a preview image captured with an initial exposure value by a camera, a first exposure value for capturing a reference image, and a second exposure value for capturing a first non-reference image, wherein the second exposure value is based on a difference between the initial exposure value and the first exposure value. Execution of the instructions may further cause the device to capture the reference image using the first exposure value, capture the first non-reference image using the second exposure value, and blend the reference image and the first non-reference image in generating an HDR image.

  • Patent number: 10498963
    Abstract: Described are systems, methods, and apparatus for generating motion extracted images having a high dynamic range (“HDR”) based on image data obtained from one or more image sensors at different times. The implementations described herein may be used with a single image sensor or camera that obtains images at different exposures sequentially in time. The images may be processed to detect an object moving within the field of view and pixel information corresponding to that moving object extracted. The non-extracted image data may then be combined to produce a motion extracted HDR image that is substantially devoid of the moving object.

  • Patent number: 10484619
    Abstract: An imaging apparatus mounted to a vehicle includes a lens, an image sensor, a light-blocking panel, and a control unit. The image sensor has a light-receiving surface which receives light from the lens and a plurality of pixels provided on the light-receiving surface. The image sensor acquires brightness of light at each of the pixels on the light-receiving surface. The light-blocking panel is disposed between the lens and the image sensor, which has a plurality of cells that are arranged so as to correspond to the plurality of pixels in the image sensor. In the light-blocking panel, transmittance of light of the cells is variable for each cell. The control unit sets the transmittance of each of the cells in the light-blocking panel corresponding to each of the pixels in the image sensor, based on the brightness of light at each of the pixels acquired by the image sensor.

  • Patent number: 10477185
    Abstract: The present disclosure relates to methods and systems that may improve and/or modify images captured using multiscopic image capture systems. In an example embodiment, burst image data is captured via a multiscopic image capture system. The burst image data may include at least one image pair. The at least one image pair is aligned based on at least one rectifying homography function. The at least one aligned image pair is warped based on a stereo disparity between the respective images of the image pair. The warped and aligned images are then stacked and a denoising algorithm is applied. Optionally, a high dynamic range algorithm may be applied to at least one output image of the aligned, warped, and denoised images.

  • Patent number: 10467732
    Abstract: Methods, apparatus and computer programs are provided for storing a set of sensor output images for multi-exposure high dynamic range processing to produce a processed image. The multi-exposure high dynamic range processing combines pixel values from one or more of the sensor output images to produce the processed image. In one example, a method comprises receiving from an image sensor a first sensor output image. The first sensor output image has a first exposure. The method also comprises receiving from the image sensor a second sensor output image. The second sensor output image has a second exposure different than the first exposure. First image pixels of the first sensor output image having pixel values which are unlikely to have a substantial contribution to the processed image are identified, and the amount of information stored in relation to the first image pixels is reduced on the basis of the identifying step.
