Methods and systems for detecting frame tears

摘要

Methods and systems for detecting frame tears are described. As one example, a mobile device may include at least one camera, a sensor, a co-processor, and an application processor. The co-processor is configured to generate a digital image including image data from the at least one camera and sensor data from the sensor. The co-processor is further configured to embed a frame identifier corresponding to the digital image at least two corner pixels of the digital image. The application processor is configured to receive the digital image from the co-processor, determine a first value embedded in a first corner pixel of the digital image, and determined a second value embedded in a second corner pixel of the digital image. The application processor is also configured to provide an output indicative of a validity of the digital image based on a comparison between the first value and the second value.

主权项

1. A method comprising:
receiving, by a processor of a mobile device, image data from at least one camera of the mobile device and sensor data from at least one sensor of a plurality of sensors of the mobile device; generating, by the processor, a digital image that includes at least the image data and the sensor data, wherein the sensor data is embedded in pixels of the digital image; embedding, by the processor, a frame identifier corresponding to the digital image in at least two corner pixels of respective corners of the digital image, wherein the digital image comprises a first segment of pixels corresponding to the image data and a second segment of pixels corresponding to the sensor data and wherein embedding the frame identifier comprises embedding the frame identifier in pixels located in at least two corner pixels of respective corners of the first segment of pixels and at least two corner pixels of respective corners of the second segment of pixels; and providing, by the processor, the digital image to an application processor of the mobile device.
