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.

Abstract: An image capture device may capture a series of images. The series of images may include a plurality of metering images interleaved with a plurality of preview images. The preview images may be captured using respective total exposure times (TETs) that are based on characteristics of at least one previously-captured metering image. A viewfinder of the image capture device may display a stream of display images. Each display image in the stream of display images may be derived from at least one of the preview images, and at least part of the capturing may occur contemporaneously with at least part of the displaying.

Abstract: Methods and systems for unlocking a screen using eye tracking information are described. A computing system may include a display screen. The computing system may be in a locked mode of operation after a period of inactivity by a user. Locked mode of operation may include a locked screen and reduced functionality of the computing system. The user may attempt to unlock the screen. The computing system may generate a display of a moving object on the display screen of the computing system. An eye tracking system may be coupled to the computing system. The eye tracking system may track eye movement of the user. The computing system may determine that a path associated with the eye movement of the user substantially matches a path associated with the moving object on the display and switch to be in an unlocked mode of operation including unlocking the screen.

Abstract: A plurality of images of a scene may be captured. Each image of the plurality of images may be captured using a different total exposure time (TET). The images in the plurality of images may be downsampled. A pixel value histogram based on pixel values of the downsampled images may be constructed. The pixel value histogram may be compared to one or more reference pixel value histograms. A payload TET may be determined based on comparing the pixel value histogram to the one or more reference pixel value histograms.

Abstract: A first set of pixels of a short exposure image and a second set of pixels of a long exposure image may be obtained. The short exposure image may have been captured using a short total exposure time (TET) and the long exposure image may have been captured using a long TET. The long TET may be greater than the short TET. The first set of pixels and the second set of pixels may be aligned. A first pixel value of a first pixel in the first set of pixels and a second pixel of a second pixel in the second set of pixels value may be compared. Based on the comparison, an alignment error value for the first pixel and the second pixel may be determined. Based at least on the alignment error value, an output image may be provided.

Abstract: Systems and methods for selecting an action associated with a power state transition of a head-mounted display (HMD) in the form of eyeglasses are disclosed. A signal may be received from a sensor on a nose bridge of the eyeglasses indicating if the HMD is in use. Based on the received signal, a first power state for the HMD may be determined. Responsive to the determined first power state, an action associated with a power state transition of the HMD from an existing power state to the first power state may be selected. The action may be selected from among a plurality of actions associated with a plurality of state transitions. Also, the action may be a sequence of functions performed by the HMD including modifying an operating state of a primary processing component of the HMD and a detector of the HMD configured to image an environment.
