摘要:
Methods and apparatus for processing images captured by a camera device including multiple optical chains, e.g., camera modules, are described. Three, 4, 5 or more optical chains maybe used. Different optical chains capture different images due to different perspectives. Multiple images, e.g., corresponding to different perspectives, are captured during a time period and are combined to generate a composite image. In some embodiments one of the captured images or a synthesized image is used as a reference image during composite image generation. The image used as the reference image is selected to keep the perspective of sequentially generated composite images consistent despite unintentional came movement and/or in accordance with an expected path of travel. Thus, which camera module provides the reference image may vary over time taking into consideration unintended camera movement. Composite image generation may be performed external to the camera device or in the camera device.

In various embodiments a camera with multiple optical chains, e.g., camera modules, is controlled to operate in one of a variety of supported modes of operation. The modes include a non-motion mode, a motion mode, a normal burst mode and/or a reduced data burst mode. Motion mode is well suited for capturing an image including motion, e.g., moving object(s) with some modules being used to capture scene areas using a shorter exposure time than other modules and the captured images then being combined taking into consideration locations of motion. A reduced data burst mode is supported in some embodiments in which camera modules with different focal lengths capture images at different rates. While the camera modules of different focal length operate at different image capture rates in the reduced data burst mode, images are combined to support a desired composite image output rate, e.g., a desired frame rate.

Methods and apparatus for capturing or generating images using multiple optical chains operating in parallel are described. Pixel values captured by individual optical chains corresponding to the same scene area are combined to provide an image with at least some of the benefits which would have been provided by capturing an image of the scene using a larger lens than that of the individual lenses of the optical chain modules. By using multiple optical chains in parallel at least some benefits normally obtained from using a large lens can be obtained without the need for a large lens. Furthermore in at least some embodiments, a wide dynamic range can be supported through the use of multiple sensors with the overall supported dynamic range being potentially larger than that of the individual sensors. Some lens and/or optical chain configurations are designed for use in small handheld devices, e.g., cell phones.

Methods and apparatus for controlling the read out of rows of pixel values from sensors corresponding to different optical chains used to capture portions of the same image area are described. The readout is controlled based on user input and/or determinations with regard to the rate of motion in captured images or portions of captured images. For a low rate of motion i, the readout rate of a sensor corresponding to a small focal length is slowed down while the pixel row readout rate of one or more sensors corresponding to one or more optical chains have larger focal lengths are allowed to proceed at a normal rate. For a high rate of motion, the read out rate of the sensor corresponding to the optical chain having the smaller focal length is allowed to proceed at the normal rate.

Illumination methods and apparatus are described. In some embodiments a lighting device includes one or more lighting modules. At least some but not necessarily all lighting modules include a light source, e.g., LED or bulb, a collimating lens positioned in front of said light source for generating a beam of light from light output by said light source and a beam flattening lens for flattening the beam of light in at least a first direction as it passes through the first beam flattening lens. In some but not necessarily all embodiments lighting modules are controlled based on which portion of a scene is being captured at a point in time thereby avoiding the need to illuminate the entire scene for the full duration of an image capture period. The lighting device may be used in combination with a rolling shutter and a sensor used to capture one or more images.

Methods and apparatus for performing zoom in and zoom out operations are described using multiple optical chains in a camera device. At least one optical chain in the camera device includes a moveable light redirection device, said light redirection device being one of a substantially plane mirror or a prism. Different zoom focal length settings correspond to different scene capture areas for the optical chain with the moveable light redirection device. Overlap between scene areas captured by different optical chains increases during zoom in and decreases during zoom out. Images captured by different optical chains are combined and/or cropped to generate a composite image corresponding to a zoom focal length setting.

Methods and apparatus for using optical chains, e.g., camera modules, with different lens configurations to support a wide range of focal lengths are described. In some embodiments a camera device includes a plurality of optical chains. In at least some embodiments non-circular outer lenses are used for optical chains with large focal lengths while optical chains of the same camera device which have smaller focal lengths use round outer lenses. Thus an exemplary camera device supports a number of different focal lengths.
摘要:
Methods and apparatus relating to image capture of image portions using optical chains with different focal lengths are described. In some embodiments different portions of a scene area of interest captured by different optical chains operating in parallel are combined. The combining in some embodiments is performed using depth information generated from two images captured by two different optical chains which capture at least some common overlapping portions of the scene area of interest. The depth information maybe generated using an image of the entire scene and one or more other images of the scene or portions of the scene area of interest. The use of multiple optical chains in parallel facilitates generation of an image with a higher overall pixel count than would be possible using a single sensor of one of the optical chains and/or with more light capture than would be captured using a single optical chain.
