  • Publication number: 20190116304
    Abstract: An image sensor of an image capture device may capture an image. The captured image may be stored in a buffer of two or more previously-captured images. An oldest image of the two or more previously-captured images may be removed from the buffer. An aggregate image of the images in the buffer may be updated. This updating may involve subtracting a representation of the oldest image from the aggregate image, and adding a representation of the captured image to the aggregate image. A viewfinder of the image capture device may display a representation of the aggregate image.

  • Publication number: 20170318233
    Abstract: A plurality of images of a scene may be obtained. These images may have been captured by an image sensor, and may include a first image and a second image. A particular gain may have been applied to the first image. An effective color temperature and a brightness of a first pixel in the first image may be determined, and a mapping between pixel characteristics and noise deviation of the image sensor may be selected. The pixel characteristics may include pixel brightness. The selected mapping may be used to map at least the brightness of the first pixel to a particular noise deviation. The brightness of the first pixel and the particular noise deviation may be compared to a brightness of a second pixel of the second image. The comparison may be used to determine whether to merge the first pixel and the second pixel.

  • Patent number: 9253375
    Abstract: The present disclosure provides example methods operable by computing device. An example method can include receiving an image from a camera. The method can also include comparing one or more parameters of the image with one or more control parameters, where the one or more control parameters comprise information indicative of an image from a substantially unobstructed camera. Based on the comparison, the method can also include determining a score between the one or more parameters of the image and the one or more control parameters. The method can also include accumulating, by a computing device, a count of a number of times the determined score image exceeds a first threshold. Based on the count exceeding a second threshold, the method can also include determining that the camera is at least partially obstructed.

  • Patent number: 9195880
    Abstract: An image-stack viewer may switch between images in an image stack based on detected interactions with the images that are displayed in the viewer. In particular, a region-of-interest (ROI) in an image may be determined based on an interaction, and image characteristics of the ROI may be evaluated in two or more images in the image stack where the ROI best represents the evaluated characteristics.

  • Patent number: 9131118
    Abstract: In one embodiment, a method comprises projecting, from a projector, a diffused on an object. The method further includes capturing, with a first camera in a particular location, a reference image of the object while the diffused is projected on the object. The method further includes capturing, with a second camera positioned in the particular location, a test image of the object while the diffused is projected on the object. The method further includes comparing speckles in the reference image to the test image. The projector, first camera and second camera are removably provided to and positioned in a site of the object.

  • Patent number: 9118841
    Abstract: A first plurality of images of a scene may be captured. Each image of the first plurality of images may be captured with a different total exposure time (TET). Based at least on the first plurality of images, a TET sequence may be determined for capturing images of the scene. A second plurality of images of the scene may be captured. Images in the second plurality of images may be captured using the TET sequence. Based at least on the second plurality of images, an output image of the scene may be constructed.

  • Patent number: 9117134
    Abstract: A base m×n tile, X, of a base image of a scene, and an alternate m×n tile, Y, of an alternate image of the scene may be obtained. An m×n blend map, B, for X and Y may also be obtained. B(i,j) may take on a first value to refer to X(i,j), or a second value to refer to Y(i,j). An m×n conflict map, C, for X and Y may further be obtained. C(i,j) may take on a third value where X(i,j) and Y(i,j) are within a threshold value of one another, or a fourth value where X(i,j) and Y(i,j) are not within the threshold value of one another. Based on B and C, the pixel values of X and Y may be merged to form an m×n tile Z.

  • Patent number: 9087391
    Abstract: A first plurality of images of a scene may be captured. Each image of the first plurality of images may be captured using a different TET. Based at least on the first plurality of images, a long TET, a short TET, and a TET sequence that includes the long TET and the short TET may be determined. A second plurality of images of the scene may be captured. The images in the second plurality of images may be captured sequentially in an image sequence using a sequence of TETs corresponding to the TET sequence. Based on one or more images in the image sequence, an output image may be constructed.

  • Patent number: 9076033
    Abstract: Embodiments described herein may help a computing device, such as a head-mountable device (HMD), to capture and process images in response to a user placing their hands in, and then withdrawing their hands from, a frame formation. For example, an HMD may analyze image data from a point-of-view camera on the HMD, and detect when a wearer holds their hands in front of their face to frame a subject in the wearer's field of view. Further, the HMD may detect when the wearer withdraws their hands from such a frame formation and responsively capture an image. Further, the HMD may determine a selection area that is being framed, within the wearer's field of view, by the frame formation. The HMD may then process the captured image based on the frame formation, such as by cropping, white-balancing, and/or adjusting exposure.

  • Patent number: 8995784
    Abstract: A structure descriptor for an m×n pixel block of an image may be determined. The m×n pixel block may contain a primary pixel having a primary pixel value and a plurality of secondary pixels having respective secondary pixel values. The structure descriptor may include a plurality of structure indicators each associated with a respective secondary pixel. The respective structure indicators may be based on the primary pixel value and the respective secondary pixel value of the associated secondary pixel. Based on the structure descriptor, a structure value for the m×n pixel block may be determined. Based on the structure value, image processing may be applied to the m×n pixel block.

  • Publication number: 20140347521
    Abstract: A total exposure time (TET) may be selected. A plurality of images of a scene may be captured using respective TETs that are based on the selected TET. At least two of the images in the plurality of images may be combined to form a merged short-exposure image. A digital gain may be applied to the merged short-exposure image to form a virtual long-exposure image. The merged short-exposure image and the virtual long-exposure image may be combined to form an output image. More of the output image may be properly-exposed than either of the merged short-exposure image or the virtual long-exposure image.
