Abstract: Disclosed is a waveform evaluating apparatus for evaluating and adjusting a waveform measured by a measurement apparatus such as a synchroscope and, more particularly, a waveform evaluating apparatus having a plurality of neural network modules formed independently for each object of judgment, in which the neural weight ratio of each neural network module is determined by causing the module to learn with a first ideal waveform module as an ideal signal and the like. Such an arrangement is also made, in which a signal in phase with the learned teacher signal extracted from the signal from an object of judgment signal is input to the input layer, and in which phasic information is detected in a phase detecting portion and a waveform is sliced in a waveform slicing portion on the basis of the phasic information. Further, such an arrangement is made, in which signal waveform data as an object of evaluation is input to the input layer and an analog output is output from the output layer.

Abstract: A CCD image pickup apparatus comprises a CCD having a plurality of horizontal scanning lines and a plurality of picture elements arranged along each of the horizontal scanning lines, a plurality of video output signal lines connected to the CCD in such a manner that a plurality of video output signals are produced by the CCD and introduced into the video output signal lines, a video signal synthesizing means for synthesizing the video output signals so as to produce a single video signal, and an A/D conversion means for analog-digital converting the single video signal produced by the synthesizing means so as to produce a digital signal. A sampling-hold means can be used between the amplifier and the synthesizing means in place of the A/D conversion means and the D/A conversion means.

Abstract: An automatic marking device for a lensmeter comprising: a lens support member; a lens holder having a lens holding member cooperative with the lens supporting member for clamping therebetween the lens movably in a plane substantially perpendicular to a measuring optical axis of the lensmeter; a marking device having a marking unit movably mounted on the lens holder and having at least one marking stylus. The marking unit is carried for rotation about an axis which is parallel to the measuring optical axis. Two hands having inner surfaces are provided and adapted for contacting adjacent edges of the lens such as to clamp the lens therebetween. A hand moving device is provided for moving the hands in the plane in accordance with the result of measurement of the refraction characteristics of the lens.
