Optical test pattern for correcting convergence defects of a color camera
摘要:
An optical test pattern for correcting convergence defects of a color camera comprises LN pattern elements (1.sub.ln) each disposed within one of the LN rectangles which result from a camera-screen lattice arrangement formed by L groups each consisting of M lines and by N columns, each pattern element being constituted by a vertical component and a diagonal component.
