Abstract

PURPOSE:To shorten an adjusting time, by detecting an inclination of a television camera, and calculating one position in either the horizontal direction or the vertical direction of the adjusting point, by said inclination. CONSTITUTION:The inclination detector detects and stores a green point position 32 address (x, y) of the reference point, and a red R point 33 address (x, y) of a signal to be adjusted, before being corrected, also detects an angle of inclination theta42, and operates y2 of a point R2. When a vertical address of a television camera has become y2 by moving the R point 33 in the vertical direction A, the comparator outputs coincidence in the vertical direction, stops the operation of a data reversible counter, and the convergence adjustment in the vertical direction ends. Subsequently, when a horizontal address x39 of the G point 32 of the reference point is made to coincide with contents of a red horizontal position counter by varying a correction data in the horizontal direction of 1 frame memory, the horizontal direction is adjusted.
