ID number is written in machine readable format which can be read by an apparatus and in man readable format which can be read by an operator to specify a photographic film. When ID number in machine readable format is read in error, ID number is represented in man readable format, and when ID number is input by an inputting device, the photographic film is specified by the input ID number, so that a predetermined testing process is effected.

Photographic film and method of testing the photographic film and

An image testing method which improves an image testing ability and enables rapid testing processing. When an operator effects testing for an image displayed at a set test position and instructs alteration of a printing condition set by the testing, the image is scrolled and the next image is displayed at the test position without the altered image being displayed. When the next image is displayed at the test position, the operator starts testing for the next image without moving his/her line of vision.

Image testing method

A photographic film inspection apparatus for inspecting a photographic film before it undergoes exposure. The photographic film inspection apparatus includes an exposure condition reading unit for reading from the photographic film information regarding exposure conditions necessary for exposure including information regarding each picture frame, a digital image information capturing unit for dividing an image recorded on each picture frame of the photographic film into a plurality of pixels and for capturing them as data, an image presence/absence detection unit for detecting whether or not an image is recorded in a predetermined photographable area of the photographic film, an exposure condition calculation unit for calculating exposure conditions used during exposure based on the exposure condition information read by the exposure condition reading unit, and a digital image information correction unit for correcting the digital image information so as to permit images captured by the digital image information capturing unit to be properly reproduced on the photosensitive material though exposed under standard exposure conditions. With this structure, various inspection processes can be performed efficiently using a single inspection apparatus before printing images on a printing paper through exposure.

Photographic film inspection apparatus

A film analyzer calculates exposure correction amounts for red, green, and blue colors in an image of an original frame of a spliced long film by using the characteristic values of a scene determined from the output of a color image sensor. For a low LATD frame having a minimum value of three-color LATDs smaller than a reference value, a density of an ND filter to be used for printing is calculated in accordance with a difference between the minimum value and the reference value. The long film is loaded into an auto-printer from the film analyzer. A photometry sensor measures three-color LATDs of an original frame set to a print station of the auto-printer. A print exposure time of each color is calculated from the three-color LATDs and exposure correction amounts. Immediately before the low LATD frame is set to the print station, an ND filter having the density determined in advance is inserted into a printing path. Three-color LATDs are measured while the ND filter is inserted into the printing path.

Photographic printing method and system

A scanner as a film analyzer, which inspects a frame on photo film, is consecutively supplied with the film by a notcher, which forms a notch in the film. The scanner includes an image area sensor which subjects the frame on the film to photometry. A pair of feeding rollers feed the film, so the film passes the photometric station. A winding shaft winds the film fed from the photometric station. A dancer roller displaces one portion of the film from a feeding path to form a loop. A set of loop checking sensors is disposed with the dancer roller, and checks displacement of the film in comparison with a predetermined upper limit. The notcher is disabled if the film displacement is greater than the upper limit. The displacement of the film is checked in comparison with a predetermined lower limit. The image area sensor is disabled if the film displacement is smaller than the lower limit.
