  • Patent number: 9467627
    Abstract: Methods and apparatus for supporting zoom operations using a plurality of optical chain modules, e.g., camera modules, are described. Switching between use of groups of optical chains with different focal lengths is used to support zoom operations. Digital zoom is used in some cases to support zoom levels corresponding to levels between the zoom levels of different optical chain groups or discrete focal lengths to which optical chains may be switched. In some embodiments optical chains have adjustable focal lengths and are switched between different focal lengths. In other embodiments optical chains have fixed focal lengths with different optical chain groups corresponding to different fixed focal lengths. Composite images are generate from images captured by multiple optical chains of the same group and/or different groups. Composite image is in accordance with a user zoom control setting. Individual composite images may be generated and/or a video sequence.

  • Patent number: 9462170
    Abstract: 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.

  • Patent number: 9451171
    Abstract: 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.

  • Patent number: 9426365
    Abstract: 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.

  • Patent number: 9423588
    Abstract: Methods and apparatus for performing a zoom operation 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. The moveable light redirection device is moved to a position in accordance with a zoom setting, and a portion of a scene area of interest in captured. Different discrete zoom setting values correspond to different positions of the moveable light redirection device resulting in different capture areas. In some embodiments, multiple optical chains with moveable light redirection devices are used to capture different portions of a scene of interest. A composite image is generated from a plurality of captured images corresponding to different optical chains. A higher zoom setting corresponds to more overlap between captured images of different optical chains.

  • Patent number: 9374514
    Abstract: Camera methods and apparatus are described where the camera device includes multiple optical chains. In various embodiments two or more of the optical chains include light redirection devices such as mirrors or prisms. Sensors corresponding to multiple different optical chains, but not necessarily all optical chains, are parallel to each other. In some embodiments sensors corresponding to different optical chains are located in the same plane at the front or rear of the camera. However other sensor mounting positions are also possible.

  • Patent number: 9325906
    Abstract: Methods and apparatus for implementing a camera having a depth which is less than the maximum length of the outer lens of at least one optical chain of the camera are described. In some embodiments a light redirection device, e.g., a mirror, is used to allow a relatively long optical chain with a relatively large non-circular outer lens. In some embodiments the light redirection device has a depth, e.g., front of camera to back of camera dimension, which is less than the maximum length of the aperture of the outer lens in the aperture's direction of maximum extent. Multiple optical chains with non-circular outer lenses arranged in different directions may and in some embodiments are used to capture images with the captured images being combined to generate a composite image.

  • Patent number: 9282228
    Abstract: 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.
