Camera arrays including multiple cameras which are spaced at various distances from one another are implemented and used. Multiple camera pairs with very different camera baselines between the cameras allows for reliable depth determinations to be made. Disparity information obtained by comparing images of a closely spaced camera pair are used to limit the search for matching image portions of images of a more distantly spaced camera pair. This allows searching for matching image portions to be constrained in a way that the complexity of searching for matching image portions can scale at a lower rate than the rate at which the baselines between cameras increases. This allows depth determinations to benefit from the accuracy obtained from using large camera baselines in a manner that is efficient from a processor utilization perspective since comparing image portions can be processor intensive if implemented without the benefit of constraints.

Camera array and methods of using captured images from a camera array for depth determination purposes

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.

Methods and apparatus for capturing and using images in a system including wipers

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.

Methods and apparatus for using filtering to improve image patch matching and/or for using depth information generated from stereo images

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 generated 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.

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 may be and often will be the same.

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.

A method for reducing the peak-to-average ratio in an OFDM communication signal is provided. The method includes defining a constellation having a plurality of symbols, defining a symbol duration for the OFDM communication signal, and defining a plurality of time instants in the symbol duration. A plurality of tones are allocated to a particular communication device, and a discrete signal is constructed in the time domain by mapping symbols from the constellation to the time instants. A continuous signal is generated by applying an interpolation function to the discrete signal such that the continuous signal only includes sinusoids having frequencies which are equal to the allocated tones.

Methods and apparatus which allow a wireless terminal () to simultaneously maintain connections with multiple base stations () are described. Each wireless terminal () is capable of supporting multiple separate timing and/or other control loops one, for each base station connection thereby allowing the connections to operate independently and in parallel. Different control signals and/or data are transmitted on each connection that is established with a base station (). In this manner base stations () receive different data allowing for asynchronous data transmission. The data received by the base stations () can be supplied to a wired asynchronous network () without the need to combine the received data prior to supplying it to the wired network (). The communications techniques of the invention can be used to implement soft handoffs without the need to duplicate data transmissions to multiple base stations.

Methods and apparatus for wireless network connectivity

Transmission techniques using configurable channels for the downlink and/or uplink are described. In one aspect, the downlink channel and/or uplink channel may be independently selected for a terminal. The terminal may establish a connection with a base station on default downlink and uplink channels. Another downlink channel and/or another uplink channel may be selected based on various factors such as channel quality, loading, and interference. The terminal would then switch to the new downlink and/or uplink channel for communication. In another aspect, the base stations broadcast sector information used by the terminals for communication and/or channel selection. The sector information may include various types of information such as the available downlink and uplink channels, the frequencies of the available channels, the loading on the available channels, and QoS information. The terminals may select a sector, a downlink channel, and/or an uplink channel based on the sector information.

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.

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.

Wireless terminals and base stations support multiple modes of dedicated control channel operation wherein wireless terminals are allocated different amounts of dedicated uplink resources for reporting control information. A set of dedicated control channel segments is utilized by a wireless terminal to communicate uplink control information reports to its serving base station attachment point. Full tone and split-tone modes of dedicated control channel operation are supported. In full tone mode, a single wireless terminal is allocated each of the dedicated control channel segments associated with a single logical tone. In split tone mode, dedicated control channel segments associated with a single logical tone are allocated between different wireless terminals, with each of the multiple wireless terminals receiving a different non-overlapping subset of the dedicated control channel segments. Logical dedicated control channel tones can be dynamically reallocated for full-tone mode use or split tone mode use.
