Equivalent tone region detecting device |
摘要 |
In an equivalent tone region detecting device, a position on a color picture is specified, so that video signals are provided separately according to the tricolor hues for the specified position through a scanning operation with a television camera, and similarly video signals are provided for another position through the succeeding scanning operation. The former and latter video signals are compared with one another, respectively, to determine whether or not the tone of the second position is equivalent to that of the specified position, whereby a region which is equal in tone to the specified position is detected.
