Exposure change control in low light environments

A method includes detecting, based on sensor data from a sensor on a mobile device, an environmental brightness measurement, where the mobile device comprises a display screen configured to adjust display brightness based on environmental brightness. The method further includes determining, based on image data from a camera on the mobile device, an extent to which the detected environmental brightness measurement is caused by reflected light from the display screen. The method additionally includes setting a rate of exposure change for the camera based on the determined extent to which the detected environmental brightness measurement is caused by reflected light from the display screen.

Multiplexed exposure sensor for HDR imaging

Optimizations are provided for a high dynamic range (HDR) sensor. This sensor is a spatially multiplexed image sensor that includes at least two sets of red, green, and blue (RGB) pixels. Each red pixel in the second set of RGB pixels is positioned proximately and sometimes, adjacently, to at least one red pixel in the first set of RGB pixels. Each green pixel in the second set of RGB pixels is positioned proximately to at least one green pixel in the first set of RGB pixels. Each blue pixel in the second set of RGB pixels is positioned proximately to at least one blue pixel in the first set of RGB pixel. This spatially multiplexed image sensor is able to generate a digital image with reduced motion blurring artifacts.

RESTORING FULL ONLINE DOCUMENTS FROM SCANNED PAPER FRAGMENTS

Searching for documents includes retrieving objects from a physical media image using a camera from a smartphone, a user selecting a subset of the objects, forming a search query based on the subset of objects, and applying the search query to a search engine to search for the documents. Retrieving objects from a media image may include waiting for a view of the camera to stabilize. Waiting for the view of the camera to stabilize may include detecting changing content of a video flow provided to the camera and/or using motion sensors of the camera to detect movement. Retrieving objects may include the smartphone identifying possible subsets of objects in the media image. The user selecting a subset of the objects may include the smartphone presenting at least some of the possible subsets to the user and the user selecting one of the possible subsets.
