Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To utilize an equalization capability of a waveform equalizer to the utmost by detecting a produced amount of deep fading on the occurrence of the fading in a transmission channel and limiting a correction amount of an amplitude distortion equalizer based on the result. SOLUTION: A control signal 105 (104) of a primary (secondary) amplitude distortion equalizer 2 (1) is limited by a control circuit 9 (8) that receives a signal 102b (102a) from a controller 12 respectively. The controller 12 applies complementary limit control to control signals 104, 105 in response to a detection level of a prescribed frequency area component of an input signal. For example, the controller 12 places no limit on the control signal 105 for the primary amplitude distortion equalizer 2 when no fading exists or the frequency of the fading is at the outside of a resonance frequency band of the secondary amplitude distortion equalizer 1 but places limit on the control signal 104 of the secondary amplitude distortion equalizer 1. On the contrary case, it is controlled so as to have the opposite control operation.

Title: Picture motion correcting device
Inventor: NISHIDA YOSHIHIRO
IPC: H04N5/232
Filed: 1990-03-29
Abstract: PURPOSE:To attain smooth correction even when a pattern is moving upward or downward by selecting whether a picture is to be outputted synchronously with an odd number field or with an even number field depending whether memory readout addresses in vertical direction are increasing from those of a preceding frame or decreasing. CONSTITUTION:Suppose that a memory readout address command (a) in vertical (line) direction is outputted with respect to an odd number/even number field signal, a command value is increased more than a preceding command for periods A, C and the command value is decreased more than the preceding command for a period B conversely. Thus, a memory readout address command (b) varies synchronously with a down-edge of an odd number/even number field signal for periods A, C and synchronously with an up-edge of an odd number/even number field signal for a period B respectively. Thus, even when the memory readout address command is increasing or decreasing, the line is smoothly read.
