A videotelephony system has an electronically controllable camera with a field of view, a visual token disposed within the field of view, and a camera controller. The camera controller is configured to detect the visual token and reconfigure the field of view relative to a detected position of the visual token.

System and method of videotelephony with detection of a visual token in the videotelephony image for electronic control of the field of view

An interface () to a video imaging device () that generates captured frames of a video image () is described. The interface includes control registers () that store at least two sets of stream parameters () corresponding to at least two regions of interest (ROIs) and a function () that generates at least two corresponding ROI video streams () that are derived from the captured frames as essentially simultaneous output signals using the at least two sets of stream parameters. In some embodiments a new selection value () is determined from a current selection value and a derivative parameter stored as a portion of a set of stream parameters. In these embodiments, the generating of the at least two corresponding ROI video streams as essentially simultaneous output signals includes using the new selection value.

An array transform system for parallel computation of a plurality of elements of an array transform includes a memory for storing an array of data elements. Each column of data elements from the memory is copied to a shifter that shifts the column of data elements in accordance with a shift value to produce a shifted column of data elements. The shifted columns of data elements are accumulated in a plurality of accumulators, with each accumulator producing an element of the array transform. A controller controls the shift value dependent upon the position of the column of data elements in the array of data elements.

A streaming data interface device () of a streaming processing system () is automatically generated by selecting a set of circuit parameters () consistent with a set of circuit constraints and generating () a representation of a candidate memory interface device based upon a set of stream descriptors. The candidate streaming data interface device is evaluated () with respect to one or more quality metrics and the representation of the candidate streaming processor circuit is output () if the candidate memory interface device satisfies a set of processing system constraints and is better in at least one of the one or more quality metrics than other candidate memory interface devices.

Automatic generation of streaming data interface circuit

A streaming processor circuit of a processing system is automatically generated by selecting a set of circuit parameters consistent with a set of circuit constraints and generating a representation of a candidate streaming processor circuit based upon the set of circuit parameters to execute one or more iterations of a computation specified by a streaming data flow graph. The candidate streaming processor circuit is evaluated with respect to one or more quality metrics and the representation of the candidate streaming processor circuit is output if the candidate streaming processor circuit satisfies a set of processing system constraints and is better in at least one of the one or more quality metrics than other candidate streaming processor circuits.
