Abstract
A vision system is disclosed having an image sensor for capturing an image, the image sensor having a lens, an image processing unit and optionally a memory unit. The image processing unit is adapted to capture and/or store in the memory, for selected areas of the image, a set of frames from the past, where the division of the image in areas and/or the number of frames from the past depend on lens parameters, position and/or orientation of the image sensor, or image parameters of the captured image.
Claims14
A vision system comprising:
- an image sensor for capturing an image;
- at least one of a sensor setting ascertaining means for establishing an image sensor parameter, wherein the sensor setting ascertaining means comprises means for capturing and/or storing and/or calculating a position or an orientation of the image sensor, and an image analysis means for analysing an image taken by the image sensor and establishing an image parameter;
- an image dividing means for dividing the image into areas as a function of the established image sensor parameter and/or the established image parameter, and for assigning to each area a number of frames to be stored in a memory.
Method of processing an image captured from an image sensor, comprising:
- capturing an image using an image sensor;
- establishing at least one of an image sensor parameter, wherein the image sensor parameter comprises information on a position or an orientation of the image sensor, and an image parameter through analysis of the image captured by the image sensor;
- dividing the image into areas as a function of the established sensor parameter and/or image parameter;
- assigning to each area a number of frames to be stored in a memory, and;
- storing the number of frames for each area into memory.
An image processing data signal for storing an image from an image sensor into a memory, the signal comprising information on a division of the image into areas and for each area information on a number of frames to be stored in the memory.
