User interface for providing feedback for handheld image capture

摘要

A method may include capturing, by a computing device and during a time interval, a plurality of images. The computing device may determine a sharpness of a first image from the plurality of images based on detection of a difference between sharpness of a first plurality of high-contrast areas within the first image and sharpness of a corresponding, second plurality of high-contrast areas within a second image from the plurality of images. The first image may be sent to a search service. Image recognition data based on the first image or indication of unavailability of the image recognition data may be received from the search service. The determining may further include detecting a movement from at least a portion of the first plurality of high-contrast areas within the first image to a corresponding portion of the second plurality of high-contrast areas within the second image.

主权项

1. A method, comprising:
receiving, by a processor, a plurality of images captured by an image capturing device during a capture period of a predetermined amount of time; identifying, by the processor, a feature located at a first position in a first image of the plurality of images and a second position in a second image of the plurality of images; responsive to determining, by the processor, that the second position is more than a threshold distance from the first position, resetting the capture period prior to expiration of the predetermined amount of time; sending the first image to a search service; and receiving, from the search service, image recognition data based on the first image.
