Abstract: PROBLEM TO BE SOLVED: To provide an image quality correction circuit for evading image degradation conventionally generated in the images of a low bit rate in the process of reproducing the images compressed and encoded at a variable transfer rate. SOLUTION: The frequency characteristics of a frequency variable circuit 3 are controlled corresponding to the result of comparing a DC obtained by passing video signals through a band-pass filter 4, an amplifier circuit 5 and a rectifier circuit 6 with a fixed value, a frequency component passed through the BPF 4 is turned to the fixed value, a high band is emphasized more for a soft screen and image quality is improved.  By MPEG for sending image compressed digital signals at a low transfer rate in video images with less high band components, since block-like noise is generated at the moment of turning to the screen of quick motion, in order to evade it, the transfer rate of data from a digital processing part is detected in a bit rate detection circuit 9, the motion state of the images is detected in a motion detection circuit 10, the characteristics of the frequency variable circuit 3 are controlled by a control circuit 8 based on both detection signals and the emphasis of the high band is stopped or reduced for the video images for easily generating the block noise.

When the arc welding is conducted under the control of the welding line copying, and the welding torch height, the method recognizes the changes of outer form of the molten pool directly under the arc, caused by a variation of root gap G of the groove, from the waveforms of arc welding voltage VT or a welding electric current I. First, a VT wave, obtained under an optimum welding condition against a gap Gref being a datum, is memorized in a memory 12 as a datum waveform VTref , and obtain a deviation part area |ΔSG|, of a current waveform VT against a datum waveform, by an absolute value integrator for each arc rotation or a rotation period.  Furthermore, plus or minus of ΔSG is determined by a code reader, and obtain ΔSG based on the integration code of deviation part behind the arc rotation position integrated by the integrator. Detection can be done in process by recognition of the current root gap G from the current ΔSG value compared with the pre-tested relationship between the ΔSG value and root gap G.
