20110185017 | METHODS AND APPARATUS FOR OBTAINING CONTENT WITH REDUCED ACCESS TIMES - Methods and apparatus for obtaining web content are disclosed. The method includes transmitting, responsive to a user request for a webpage, a primary-content-item-request to obtain a primary content item of the webpage. And a request list that is stored on the client device is accessed to obtain a list of secondary-content-item-requests that are typically needed, in connection with the primary content item, to render the webpage. The secondary-content-item-requests are then transmitted in advance of receiving a response to the primary-content-item-request. And the web page is rendered using the primary content item and the secondary content items. | 07-28-2011 |
20140307044 | Reference image selection for motion ghost filtering - Exemplary methods, apparatuses, and systems for image processing are described. One or more reference images are selected based on image quality scores. At least a portion of each reference image is merged to create an output image. An output image with motion artifacts is compared to a target to correct the motion artifacts of the output image. | 10-16-2014 |
20140307960 | Generation of ghost-free high dynamic range images - Apparatuses and methods for reading a set of images to merge together into a high dynamic range (HDR) output image are described. Images have a respective HDR weight and a respective ghost-free weight. Images are merged together using the weighted average of the set of input images using the ghost-free weight. A difference image is determined based on a difference between each pixel within a HDR output image and each respective pixel within a reference image used to create the HDR output image. | 10-16-2014 |
20140362773 | LOCAL IP ACCESS SCHEME - Local IP access is provided in a wireless network to facilitate access to one or more local services. In some implementations, different IP interfaces are used for accessing different services (e.g., local services and operator network services). A list that maps packet destinations to IP interfaces may be employed to determine which IP interface is to be used for sending a given packet. In some implementations an access point provides a proxy function (e.g., a proxy ARP function) for an access terminal. In some implementations an access point provides an agent function (e.g., a DHCP function) for an access terminal. NAT operations may be performed at an access point to enable the access terminal to access local services. In some aspects, an access point may determine whether to send a packet from an access terminal via a protocol tunnel based on the destination of the packet. | 12-11-2014 |
20140375865 | SYSTEMS AND METHODS TO SUPER RESOLVE A USER-SELECTED REGION OF INTEREST - Systems, devices, and methods are described for efficiently super resolving a portion of an image. One embodiment involves capturing, using a camera module of a device, at least one image of a scene, and creating a higher resolution image of a user-selected region of interest. The super resolution of the region of interest may be performed by matching a high resolution grid with a grid that is at the resolution of a device camera, populating the high resolution grid with information from an image from the camera, and then populating the remaining points of the grid that are not yet populated. | 12-25-2014 |
20150062370 | METHOD AND APPARATUS FOR GENERATING AN ALL-IN-FOCUS IMAGE - Techniques are described for generating an all-in focus image with a capability to refocus. One example includes obtaining a first depth map associated with a plurality of captured images of a scene. The plurality of captured images may include images having different focal lengths. The method further includes obtaining a second depth map associated with the plurality of captured images, generating a composite image showing different portions of the scene in focus (based on the plurality of captured images and the first depth map), and generating a refocused image showing a selected portion of the scene in focus (based on the composite image and the second depth map). | 03-05-2015 |
20150063694 | TECHNIQUES FOR COMBINING IMAGES WITH VARYING BRIGHTNESS DEGREES - Techniques are described for combining two or more images that are taken with varying brightness degrees to generate a composite image. In one embodiment, at least two weight masks are generated based on one or more characteristics of the two or more images. A first image A first weight mask is used to combine color channels of one or more pixels of the two or more images and a second weight mask is used to combine intensity channels of the one or more pixels of the two or more images. | 03-05-2015 |
20150063718 | TECHNIQUES FOR ENHANCING LOW-LIGHT IMAGES - Techniques are described for enhancing quality of a first image that is captured in a low-light environment. In one embodiment, a second image is generated by brightening a plurality of pixels in the first image based on a predefined criteria. A third image is generated using an edge-preserving noise reduction algorithm based on the second image. Further, a composite image is generated by obtaining a weighted average of the first image and the third image. The techniques described herein can be applied to an image and/or to each frame of a video that is captured in low-light environments. | 03-05-2015 |
