Abstract: An example image capture device determines a region of interest using a first image captured while a light source is powered off and a second image captured while a light source is powered on and uses the region of interest to automatically set configurations. In one example an image capture device includes a controlled light source an image sensor configured to capture images and a processing unit configured to cause the image sensor to capture a first image of a scene while the controlled light source is powered off cause the image sensor to capture a second image of the scene while the controlled light source is powered on calculate luminance differences between a plurality of regions in the first image and a plurality of collocated regions in the second image and determine that a region of interest includes those regions for which the luminance differences exceed a threshold.

Abstract: This disclosure relates to techniques for providing hands free augmented reality on a wireless communication device (WCD). According to the techniques an application processor within the WCD executes an augmented reality (AR) application to receive a plurality of image frames and convert the plurality of image frames into a single picture comprising the plurality of image frames stitched together to represent a scene. The WCD executing the AR application then requests AR content for the scene represented in the single picture from an AR database server receives AR content for the scene from the AR database server and processes the AR content to overlay the single picture for display to a user on the WCD. In this way the user may comfortably look at the single picture with the overlaid AR content on a display of the WCD to learn more about the scene represented in the single picture.

Abstract: Apparatus and methods for conditional display of a stereoscopic image pair on a display device are disclosed. Particularly some implementations include receiving a first image and a second image determining a vertical disparity between the first image and the second images and displaying a stereoscopic image pair if the vertical disparity is below a threshold. Some implementations provide for correcting the vertical disparity by generating at least one corrected image and generating the stereoscopic image pair based on the corrected image. Some implementations may evaluate the quality of the stereoscopic image pair and display either a two dimensional image or the stereoscopic image pair based on the evaluation.

Abstract: Techniques are described for dynamic automatic exposure compensation within image capture devices. The techniques include dynamically adjusting a default target brightness for a scene to compensate an exposure value (EV) selected by an automatic exposure process. A sensor array obtains light information from the scene at a default target brightness and an image capture controller calculates brightness values of a plurality of regions in the scene based on the light information. An automatic exposure compensation module dynamically adjusts the default target brightness based on the brightness values for the plurality of regions in the scene and threshold values set for the sensor array to set an adjusted target brightness. The sensor array may then capture an image frame of the scene using an EV for the adjusted target brightness. The techniques also include building a hysteresis zone to substantially stabilize the adjusted target brightness over a sequence of image scenes.

Abstract: Described are a system, apparatus, and method to capture a stereoscopic image pair using an imaging device with a single imaging sensor. Particularly, discussed are systems and methods for capturing a first and second image through an image sensor, determining a vertical and horizontal disparity between the two images, and applying corrections for geometric distortion, vertical disparity, and convergence between the two images. Some embodiments contemplate displaying a directional indicator before the second image of the stereoscopic image pair is captured. By displaying a directional indicator, a more optimal position for the second image of the stereoscopic image pair may be found, resulting in a higher quality stereoscopic image pair.
