<p>PROBLEM TO BE SOLVED: To cancel the increase of the error component of quantization with the lapse of time and to display a precise rotation angle. SOLUTION: In a picture processor constituted of an angular velocity detection sensor, an operation circuit, an A/D converted and an operation processor, the operation of the rotation angleθ(t) from a prescribed original point is calculates asθ(t)=θ(t-1)+V(t)-k×θ(t-1). Here,θ(t-1) is set to be a previous angle operation result, V(t) to be a value obtain by amplifying and A/D- converting angular velocity sensor output by an operation amplifier circuit and (k) to be an arbitrary proportional constant.</p> |
