A user gestures with a wireless mobile phone device to control some aspect of its operation, or the operation of a remote system with which the device communicates. (The gestures may be sensed by tracking movement of a feature across a field of view of a mobile phone device camera.) The resultant operation may additionally depend on other data obtained by the wireless device, e.g., obtained from an electronic or physical object, or sensed from the environment. A variety of other features and arrangements are also detailed.

A digital portable communications device (1) for communication via a communications network (28) has circuitry for exchanging video signals between the device and an external video apparatus (25; 31). The circuitry for exchanging video signals is arranged to exchange the video signals in the form of analog video signals. When analog video signals are used, the exchange of video signals with external video apparatuses is not limited to apparatuses adapted to a specific protocol for the exchange of digital video signals. Thus, it is not needed to have specific software drivers for different digital protocols in the communications device in order to communicate with a camera or a display unit. Any digital or analog camera, video recorder or video display unit can be used as an accessory to the communications device.

Arrangements involving portable devices (e.g., smartphones and tablet computers) are disclosed. One arrangement enables a content creator to select software with which that creator's content should be rendered—assuring continuity between artistic intention and delivery. Another utilizes a device camera to identify nearby subjects, and take actions based thereon. Others rely on near field chip (RFID) identification of objects, or on identification of audio streams (e.g., music, voice). Some technologies concern improvements to the user interfaces associated with such devices. Others involve use of these devices in connection with shopping, text entry, sign language interpretation, and vision-based discovery. Still other improvements are architectural in nature, e.g., relating to evidence-based state machines, and blackboard systems. Yet other technologies concern use of linked data in portable devices—some of which exploit GPU capabilities. Still other technologies concern computational photography. A great variety of other features and arrangements are also detailed.

Cameras are installed at the front, right, left, and back side of a vehicle, and two feature points are located at each of the common field of view areas between the front-right cameras, front-left cameras, back-right cameras, and back-left cameras. A camera calibration device includes a parameter extraction unit for extracting transformation parameters for projecting each camera's captured image on the ground and synthesizing them. After transformation parameters for the left and right cameras are obtained by a perspective projection transformation, transformation parameters for the front and back cameras are obtained by a planar projective transformation so as to accommodate transformation parameters for the front and back cameras with the transformation parameters for the left and right cameras.

Another utilizes a device camera to identify nearby subjects, and take actions based thereon. Others rely on near field chip (RFID) identification of objects, or on identification of audio streams (e.g., music, voice). Some technologies concern improvements to the user interfaces associated with such devices. For example, some arrangements enable discovery of both audio and visual content, without any user requirement to switch modes. Other technologies involve use of these devices in connection with shopping, text entry, and vision-based discovery. Still other improvements are architectural in nature, e.g., relating to evidence-based state machines, and blackboard systems. Yet other technologies concern computational photography. A great variety of other features and arrangements are also detailed.

A method for producing video simulations uses two-dimensional HDR images and LIDAR optical sensor data to deliver a photo-realistic simulated sporting event experience to a display. The playing environment is mapped using a data collection process that includes contour mapping the environment, photographing the environment, and associating the images with the contour mapping data. Preferably, the HDR camera is used in conjunction with a differential global positioning system that records the position and heading of the camera when the photo is taken. A polygon mesh is obtained from the contour data, and each image is projected onto a backdrop from the perspective of a simulated camera to create a set, which is then stored in a set database. The simulated environment is created by selecting the set needed for the simulation and incorporating simulation elements into the set before rendering the simulated camera's view to the display.
