摘要： Methods and apparatus for processing images captured by cameras for use in stereo depth determinations are described and/or for using depth information generated by processing such images is described. Images are captured using a reference camera and at least one additional camera. Filtering is implemented as part of a patch matching process to reduce the risk of erroneous matches, e.g., due to image blur in one image but not another. The filtering may be, and sometimes is, implemented on a patch basis. A candidate patch is generated by filtering a portion of an image captured by a camera, e.g., a second camera by performing a sharpening or blurring operation to a portion of the image to generate a candidate patch. The amount of blurring or sharpening that is applied to generate the candidate patch depends, in some embodiments, on the relative difference between the candidate patch and the reference patch. Thus in some embodiments the amount of sharpening and blurring is dependent on both the content of the reference patch as well as the portion of the second image used to generate the candidate patch.

摘要： Methods and apparatus for using a controllable filter, e.g., an liquid crystal panel, in front of a camera are described. The filter is controlled based on the luminosity of object in a scene being captured by the camera to reduce or eliminate luminosity related image defects such as flaring, blooming or ghosting. Multiple cameras and filters can be used to capture multiple images as part of a depth determination processes where pixel values captured by cameras at different locations are matched to determine the depth, e.g., distance from the camera or camera system to object in the environment. Pixel values are normalized in some embodiments based on the amount of filtering applied to a sensor region and sensor exposure time. The filtering allows for regional sensor exposure control at an individual camera even though the overall exposure time of the pixel sensors maybe and often will be the same.

摘要： A wiper is controlled to sweep a surface area, e.g., a portion of a windshield, in front of a camera, e.g., a camera mounted inside a vehicle. An image captured from the camera after the wiper completes, e.g., immediately completes, the sweep of the surface area in front of the camera is used in generating a depth map. In some embodiments a first wiper is controlled to clear a surface area in front of a first camera while a second wiper is controlled to clear a surface area in front of second camera at the same time, and the first and second cameras are synchronized to initiate image capture at the same time, capturing images through recently cleared area, and the captured images are used to generate a depth map. A vehicle control operation, e.g., a direction, braking or speed control operation is performed based on the depth map.

摘要： Camera device including multiple optical chains, e.g., camera modules, some of which have different orientations relative to the base of the camera device and methods of using such a camera device are described. The orientation of the camera modules within the camera device is taken into consideration when determining the direction in which lines of the sensors of the individual camera modules are read out. Information with regard to the read out direction to be used with particular camera modules is stored in some embodiments and used to control the readout of sensors, e.g., sensors which use a rolling shutter to capture images of a scene area. The sensors may have the same field of view or overlapping fields of view.

摘要： A camera device including multiple optical chains receives user input indicating one or more user selectable control option setting(s), e.g., a user selected depth of field control option setting and an aspect ratio control option setting. The indicated control option settings are stored in memory in the camera device. Multiple optical chains of the camera device capture an image during an image capture time interval. A set of captured images are stored in a file along with metadata including the user indicated control option settings. A composite image is generated from a set of captured images in accordance with the stored indicated control option settings, e.g., generating a composite image with a user selected depth of field and/or a user selected aspect ratio. In some embodiments, at least some of the user selected control option settings are not used during image capture operations but are used in subsequent image processing.

摘要： Methods and apparatus relating to a camera including one or more optical chains with a light redirection device, e.g., mirror, and an outer protective cover are described. The cover maybe a flat or sloped surface or a lens. Features avoid stray light rays from reaching an image sensor of an optical chain. In some but not all embodiments a 2-sided anti-reflection coating is used on the cover to avoid or reduce back reflections from the cover into the optical system. In some embodiments mirror angles are limited to a range in which stray light reflections are directed away from the camera module. In some embodiments a tilted cover configuration is used where the cover is sloped relative to a face of the camera and/or camera module. Different features such as the sloped cover glass, control of mirror angle, and/or antireflective coating can be used alone or in combination.

摘要： A camera device with a sensor which is mounted at an angle relative to a mounting surface or other reference surface is described. Camera modules, which include mirrors for light redirection, which are mounted at different angles in the camera device have sensors with different amounts of rotation. In some embodiments modules without mirrors use camera modules without rotated sensors while camera modules with mirrors may or may not use sensors which are rotated depending on the angle at which the modules are mounted in the camera device. By rotating the sensors of some camera modules rotation that maybe introduced by the angle at which a camera module is mounted can be offset. The images captured by different camera modules are combined in some embodiments without the need for computationally rotating an image thanks to the rotation of the sensor in the camera module used to capture the image.
