Filed: 1993-10-26
Abstract: PURPOSE:To reduce arithmetic operation processing and to attain stable pull-in by allocating a same tap coefficient to plural taps of each prescribed number adjacent to each other in a transversal filter. CONSTITUTION:When a 2BIQ code is sent/received via a digital subscriber line 5, an echo canceller 1 (decision feedback equalizer 3) include a transversal filter 6, 7. Then, an echo canceller 1 generates an echo replica used to cancel bypassed transmission signal.

Title: Image processor
Inventor: UENO SATOSHI
IPC: G06T1/00
Filed: 1986-11-11
Abstract: PURPOSE:To obtain a sharp binary image even from an input picture to which an object and its background are almost at the same light level by sequentially varying a threshold with changes in the video level of an input signal. CONSTITUTION:A comparator 7 compares the levels of signals outputted from a video processor 4. If a video signal goes to a high value, by the effect of a reversal attenuator 5, the threshold may be and a binarization signal may be set to a high level. As a result the light part of an image is emphasized. Conversely, if the video signal goes to a low value, the threshold is increased to emphasize the dark part of the image. Thus, even if the difference between the object and the background is not clear, a precise binarization can be made with the aid of the threshold by using a difference when the difference of some extent exists. Based on this the principle, the comparator 7 compares the levels, and outputs the high level signal if the video signal is higher than the threshold, otherwise, it outputs the low level signal.
