Image sensor cropping images in response to cropping coordinate feedback

摘要

Reducing consumption of image sensor processor bandwidth includes capturing an image containing subject matter with an image sensor and cropping the image to generate a cropped image. Cropping the image is performed by the image sensor in response to coordinates received from an image sensor processor. The cropped image is sent from the image sensor to the image sensor processor and new coordinates based on a position of the subject matter in the cropped image are determined with the image sensor processor. The new coordinates are then sent to the image sensor.

1. A method for reducing consumption of image sensor processor bandwidth, the method comprising:
capturing an image containing subject matter with an image sensor; cropping the image to generate a cropped image, wherein cropping the image is performed by the image sensor in response to coordinates received from an image sensor processor; sending the cropped image from the image sensor to the image sensor processor; determining, with the image sensor processor, new coordinates based on a position of the subject matter in the cropped image, wherein said determining the new coordinates based on the position of the subject matter comprises determining the new coordinates based on movement between the cropped image and a previously cropped image that was cropped by the image sensor processor prior to cropping the cropped image; and sending the new coordinates to the image sensor.
