Abstract
Methods for obtaining a shallow depth of field effect (DOF) and improved signal-to-noise (SNR) in an image through synthetically increase the camera aperture of a compact camera using at least one actuator included in such a camera for other known purposes, for example for providing optical image stabilization (OIS). The synthetically enlarged camera aperture enables to take a plurality of images at different aperture positions. The plurality of images is processed into an image with shallow DOF and improved SNR.
Claims18
A method, comprising:
- in a camera that includes a camera aperture, an image sensor and an actuator,
- operating the actuator to move the camera aperture relative to the image sensor to a plurality of different aperture positions;
- capturing a plurality of images, wherein each image of the plurality of images is captured at a respective different camera aperture position;
- and
- processing the plurality of images into a single image that exhibits a shallow depth of focus effect.

A camera, comprising:
- a camera aperture;
- an image sensor;
- and
- an actuator operative to move the camera aperture relative to the image sensor to a plurality of different aperture positions,
- wherein the camera is operative to capture a plurality of images, wherein each image of the plurality of images is captured at a respective different aperture position, and to process the plurality of images into a single image that exhibits a shallow depth of focus effect.
