IMAGE ORIENTATION ADJUSTMENT BASED ON CAMERA ORIENTATION

摘要

Systems and methods are disclosed to rotate an image recorded by an image sensor to compensate for angular rotation or tilt of the image sensor. For example, a camera can include an image sensor having a plurality of pixels arranged in an array, an accelerometer, a memory, and a processing unit. The processing unit can be configured to read a first plurality of pixels corresponding to an imaging area of the image sensor. The processing unit can also be configured to receive an acceleration value from the accelerometer, and determine an tilt angle value from the acceleration value that represents at least in part the tilt of the image sensor relative to the Earth's gravitational field or the horizon. The processing unit may also be configured to rotate at least a subset of the first plurality of image pixels of the image sensor based on the tilt angle value.

1. A camera comprising:
an image sensor having a plurality of image sensor elements arranged in an array; a motion sensor; a memory; and a processing unit coupled with the image sensor, the accelerometer, and the memory, the processing unit configured to:
receive an image from the image sensor, wherein the image comprises a plurality of pixels that comprise a value received from a corresponding image sensor element of the image sensor;receive a value from the motion sensor that corresponds at least in part to an orientation of the image sensor relative to the Earth's gravitational field; androtate the pixels in the image based on the value.
