Image capture system with motion compensation

摘要

An example image system may include a lens that produces an image, an image sensor, an image stabilizer, and a controller. This image sensor has a first edge and an opposite second edge. The first edge is placed closer to lens such that it focuses on more distant objects. The image stabilizer provides a time-varying compensation of image motion at the image sensor. The controller operates the image capture system in a repeating cycle where the sensor exposes and reads out an image progressively from one edge to the opposite edge. The controller operates the image stabilizer to provide an image motion compensation that varies in time such that the image motion compensation is greater when exposing and reading the second edge of the sensor than when exposing and reading the first edge of the sensor.

主权项

1. An image capture system comprising:
a lens that produces an image; an image sensor having a first edge and a second edge opposite the first edge, the first edge being placed closer to lens such that the lens focuses on more distant objects; an image stabilizer configured to provide a time-varying compensation of image motion at the image sensor; and a controller configured to:
operate the image capture system in a repeating cycle, wherein during each cycle the controller operates the sensor to expose and read out an image progressively from one edge to the opposite edge, andoperate the image stabilizer to provide an image motion compensation that varies in time such that the image motion compensation is greater when exposing and reading the second edge of the sensor than when exposing and reading the first edge of the sensor.
