A frame rate conversion section converts a frame rate for an input image. A motion vector detection section detects motion vector V0 between frames in the input image and finds motion vector V after the frame rate conversion based on the detected motion vector V0.

A sub-field conversion section converts each frame into luminescent data for multiple sub-fields. A sub-field correction section relocates the luminescent data for the sub-fields using the corrected motion vector V1.

Abstract: An Ethernet-compatible synchronization process between isolated digital data streams assures synchronization by embedding an available time code from a first stream into data locations in a second stream that are known a priori to be unneeded. Successive bits of time code values, generated as a step in acquiring and digitizing analog sensor data, are inserted into least-significant-bit locations in a digitized audio stream generated along with digitized image data by a digital video process. The overwritten LSB locations are shown to have no discernable effect on audio reconstructed from the Ethernet packets. Telemetry recovery is the reverse of the embedment process, and the data streams are readily synchronized by numerical methods.

Abstract: An image acquisition system for machine vision systems decouples image acquisition from the transmission of the image to a host processor by using a programmable imager controller to selectively disable and enable the transmission of data to the host and by using a system of buffers to temporarily store image data pending allocation of memory. This enables the image acquisition system to acquire images asynchronously and to change the exposure parameters on a frame-by-frame basis without the latency associated with the allocation of memory for storage of the acquired image. The system architecture of the invention further permits interruption and resumption of image acquisition with minimal likelihood of missing data. Data throughput is further enhanced by transmitting to the host only that data corresponding to the region of interest within the image and discarding the data from outside of the region of interest at the camera stage.

Abstract: The present invention provides an innovative technique for rapidly and accurately determining whether two audio samples match, as well as being immune to various kinds of transformations, such as playback speed variation. The relationship between the two audio samples is characterized by first matching certain fingerprint objects derived from the respective samples. A set (230) of fingerprint objects (231,232), each occurring at a particular location (242), is generated for each audio sample (210). Each location (242) is determined in dependence upon the content of the respective audio sample (210) and each fingerprint object (232) characterizes one or more local features (222) at or near the respective particular location (242). A relative value is next determined for each pair of matched fingerprint objects. A histogram of the relative values is then generated. If a statistically significant peak is found, the two audio samples can be characterized as substantially matching.

The synchronization signal detection circuit determines a precise main path by determining powers in consideration of the influence of multiple paths near signals located at a peak value location and guarantees a stable operation of an equalizer by using error values output from a decoder to generate a synchronization locking control signal.
