TLDR
In this article, the frame position data is compared with an actual amount of film advancement detected when advancing the frame toward a print position, so as to determine whether the frame specification data corresponds to the actual frame placed in the print position.Abstract:
In an auto-printer, wherein original frames to be printed are sequentially and automatically printed at an optimum exposure amount, which is determined based on frame specification data which includes exposure correction data, frame number and position data and stored during negative inspection. The frame position data is compared with an actual amount of film advancement detected when advancing the frame toward a print position, so as to determine whether the frame specification data corresponds to the actual frame placed in the print position. Simultaneously, the actual frame number of the frame placed in the print position is determined based on frame number bar code read from the photographic film during advancing the film, so as to compare the actual frame number with the frame number data. If it is determined by either one of the above described comparison that the frame specification data does not correspond to the actual frame, the auto-printer is automatically changed from an auto-print mode to a manual print mode.read more

Method of making an index print
TL;DR: In this paper, a holder (24) and a method of making an index print using the holder(24) is described. But this method is not suitable for index printing, as it requires the insertion of at least one filmstrip (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 30) into the holder and scanning the holder to obtain a digital record.

Picture frame number discriminating method and apparatus therefor
Yoichi Ujiie,Syuji Tahara +1 more
TL;DR: In this article, the number of frames between the distance is obtained through division of the obtained distance by the pitch between frame number bar codes or frame numbers, and a frame number of a frame positioned at the film mask is discriminated based on the obtained number of frame and the read frame number.
Patent
Photographic film with latent image multi-field bar code and eye-readable symbols.
TL;DR: A multi-field latent image bar code is photographically recorded in every half frame of a strip of photographic film, at least one of the fields of the code representing information pertaining to the film type and another one representing the half-frame number as mentioned in this paper.

Photograph printing method
TL;DR: In this paper, the authors proposed to reduce an overall processing time by as much as overlapped stages by starting a printing-exposing operation before the operation of the exposure quantity of light of three colors is finished and orderly cutting color light which reaches the exposure quantities by a filter after the operation is finished.
