Abstract: PURPOSE:To reduce power consumption by decreasing a high speed operation section of a delay circuit. CONSTITUTION:The filter is the transversal filter with (2M+1) taps in which waveform is shaped with respect to an input signal quantized at a frequency mfs being a multiple of(m)of a transmission data speed fs and a data signal whose speed is fs is outputted.

Abstract: PURPOSE:To reduce the loss of the title circuit by providing plural analog switches and a logic gate or the like so as to synthesize two analog signals in using a logic IC and to output correctly an intermediate level of a synthesis signal. CONSTITUTION:When a high level is given to both input terminals 1, 2, only the output of an AND circuit 4 goes to a high level among outputs of the AND circuit 4, an exclusive OR circuit 5 and a NOR circuit 6. Thus, an analog switch 7 is made conductive and other analog switches 8, 9 are opened and a positive power voltage is outputted at an output terminal. When either an input signal of the terminals 1, 2 is at a high level and the other is at a low level, a constant voltage potential set to a half the power voltage is outputted and when both the input signals are at a low level, a negative power voltage is outputted. Even when a logic IC is employed for the switches 7, 8, 9, the two analog signals are synthesized and the intermediate of the synthesized signal is outputted correctly and the circuit loss is reduced.

Abstract: PURPOSE:To attain a picture processing even in travel conditions when a luminous quantity lacks so as to detect the ends of a road by deciding the ends of the travel road based on information on an area upper than an infinite line when the external luminous quantity is less than a prescribed value. CONSTITUTION:When the external luminous quantity is less than the prescribed value, the ends of the travel road is decided based on information on the area upper than the infinite line. Namely, the road lights and the like of the travel road, whose luminous quantity lacks, are continuously arranged, picture data of the road lights photographed on the upper part of the screen are processed and the ends of the travel road is detected. When a vehicle travels the center of a tunnel, for example, the position of a virtual center line 35 is obtained from the projection of a center point Q between sodium lights 30a and 30b for the road surface. Consequently, travel control can be executed by setting the virtual center line 35 to be an objective point. Thus, picture data of the road lights and the like photographed at the upper part of the screen of an image-pick up picture are processed so as to detect the ends of the travel road even if the actual end of the path cannot be recognized due to the lack of the luminous quantity.
