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.
Claims27
A method, comprising:
- a) providing a camera that includes a camera aperture, a lens having a lens optical axis, an image sensor, and an actuator;
- and
- b) operating the actuator to synthetically enlarge the camera aperture to obtain a shallow depth of focus effect in an image formed from a plurality of images obtained with the image sensor.
A camera, comprising:
- a) a camera aperture;
- b) a lens having a lens optical axis;
- c) an image sensor;
- and
- d) an actuator operative to synthetically enlarge the camera aperture to obtain a shallow depth of focus effect in an image formed from a plurality of images obtained with the image sensor.
