Abstract: Various features relating to reducing and/or eliminating noise from images are described. In some embodiments depth based denoising is used on images captured by one or more camera modules based on depth information of a scene area and optical characteristics of the one or more camera modules used to captures the images. In some embodiments by taking into consideration the camera module optics and the depth of the object included in the image portion, a maximum expected frequency can be determined and the image portion is then filtered to reduce or remove frequencies above the maximum expected frequency. In this way noise can be reduced or eliminated from image portions captured by one or more camera modules. The optical characteristic of different camera modules may be different. In some embodiments a maximum expected frequency is determined on a per camera module and depth basis.

Abstract: 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.

Abstract: An exemplary camera calibration apparatus includes a movable, e.g., rotatable, support structure which is controllably positioned to allow for image capture of different test patterns and image capture of the same pattern at different distances by a mounted camera. A first test pattern is mounted on a wall, e.g., a pyramid shaped 4 sided wall formed by panels surrounding the camera under calibration. The movable support structure has a first mirror attached to a first side and has a second test pattern attached to a second side. A second mirror mounted on an internal sidewall of the calibration apparatus housing facilities a different image path distance between the camera capturing the image of the first test pattern and the first test pattern. The exemplary camera calibration apparatus is well suited for efficiently calibrating camera devices including a plurality of camera modules, e.g., optical chains, in a relatively small area.

Abstract: Methods and apparatus for reading out pixel values from sensors in a synchronized manner are described. Readout of rows of pixel values from different sensors are controlled so that pixel values of different sensors corresponding to the same portion of a scene are read out in a way that the same portions of a scene are captured at the same or nearly the same time by different sensors. In one embodiment a first sensor which captures a large scene area alternates between reading out rows of pixel values from a top portion and a bottom portion of the first sensor while sensors corresponding to smaller areas of the scene read out rows of pixel values in a consecutive manner. Sensors may read out rows of pixel values at the same rate despite corresponding to optical chains with different focal lengths. The image captured by the first sensor facilitates image combining.
