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.
Claims25
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, wherein the operating the actuator to synthetically enlarge the camera aperture includes operating the actuator to move the lens relative to the image sensor in a first direction substantially perpendicular to the lens optical axis.
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, wherein the actuator is operative to synthetically enlarge the camera aperture by moving the lens relative to the image sensor in a first direction substantially perpendicular to the lens optical axis.
