Abstract: In order to continue transmission of extra traffic in the absence of an unused transmission path, a transmission system of the present invention is a wireless transmission system comprising two or more wireless transmission devices are connected via a plurality of wireless transmission paths. The wireless transmission device is a wireless transmission device for transmitting traffic to another wireless transmission device via a wireless transmission path selected from a plurality of connected wireless transmission paths. The wireless transmission system comprises a switching control unit which judges, when a fault has occurred in the wireless transmission path for transmitting the traffic, whether the traffic is transmittable with use of the wireless transmission path in which the fault has occurred, namely, a faulty transmission path, and which selects the faulty transmission path, as the wireless transmission path for transmitting the traffic, when judging that the traffic is transmittable.

Abstract: A method for color misregistration detection. Input image data is buffered and transferred to vector space. An examination window for a current pixel is established and foreground and background pixels within that window are selected. The current pixel is examined to determine if it is in an edge of a scanned object. If the current pixel is in an edge, it is deemed to have color misregistration. For pixels that have been deemed to have color misregistration, a correction value is determined and then adjusted prior to being applied to the pixel value.

Abstract: A method for color misregistration detection. Input image data is buffered and transferred to vector space. An examination window for a current pixel is established and foreground and background pixels within that window are selected. The current pixel is examined to determine if it is in an edge of a scanned object. If the current pixel is in an edge, it is analyzed for color misregistration. The analysis includes an application of Stokes' theorem. If the results of the application of Stokes' theorem indicate that the color misregistration is above a threshold, the pixel is identified as having color misregistration.
