Title: Method and device for deciding position of picture frame
Inventor: ITO TOSHIO
IPC: G03B27/32
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To specify the position of a picture frame, which is recorded on a photographic film, which a high precision. SOLUTION: The film base density is detected from a one-photographic film portion of picture data. A threshold is added to the film base density to obtain a reference value. Pixels exceeding this reference value are extracted from the overall area of the photographic film. It is decided whether or not an approximately rectangular pixel group consisting of a set of extracted pixels is close to a standard picture frame size. Position data of the pixel group which is close to the standard picture frame size is registered as a picture frame having distinct edges. An average frame length and an average gap are obtained on the basis of settle edge positions. With respect to pictures the edge positions of which are undetermined, edge position candidates are extracted.  Distances between edge position candidates and a determined edge are found in the film forwarding direction and the film reversing direction. One of these distances which is the closest to an average value found from settled frames is determined as the edge position. Thus edge positions are specified with a high precision with respect to frames the edge positions of which are indistinct.
