Abstract: A magnetic head and line sensor are mounted along the transport passage of a color negative film. The magnetic head reads trimming information recorded on a magnetic recording layer of the negative film, and sends the trimming information to an image processing unit. The line sensor scans an original frame of the negative film synchronously with the transportation of the film and reads the image data of the frame one line after another. In accordance with the trimming information, the image processing unit generates image data for a trimmed image so as to fully use the width of the color paper, and sends the image data to a line printer unit. The line printer unit scans a light beam synchronously with the transportation of the color paper, to record the trimmed image, one line after another, on the color paper.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A radiation image of an object is formed with radiation, which has passed through the object. The radiation image is then photoelectrically read out, and an image signal made up of a series of image signal components representing the radiation image is thereby obtained. Frequency processing is carried out on the image signal in accordance with a predetermined emphasis coefficient .beta.. When the frequency processing is carried out on image signal components corresponding to a peripheral region in the radiation image, which peripheral region has a predetermined width, the value of the emphasis coefficient .beta. used during the frequency processing is decreased monotonously from a value for an image signal component corresponding to a position on the radiation image, which position is closer to the middle part of the radiation image, to a value for an image signal component corresponding to a position on the radiation image, which position is closer to the exterior of the radiation image.

Abstract: In image signal storing method and apparatus, a continuous tone image signal representing a continuous tone image and a binary image signal representing a binary image, which carries information giving specifics about the continuous tone image, are obtained. A redundancy imparting process is carried out on the binary image signal in accordance with irreversible signal compression processing such that the information represented by the binary image signal may not be reduced when the irreversible signal compression processing is carried out. Thereafter part of the continuous tone image signal, which part corresponds to part of the region in the continuous tone image, is replaced by the binary image signal, which has been obtained from the redundancy imparting process. The irreversible signal compression processing is then carried out on an image signal, which has been obtained from the replacement. An image signal, which has been obtained from the irreversible signal compression processing, is then stored.

Abstract: Disclosed herein is a radiation image information reading apparatus for reading radiation image information recorded on a stimulable phosphor sheet and erasing the remaining radiation image information from the sheet. The apparatus generally includes a reading unit, an erasing unit, a light-intransmissive device, a first filter and a second filter. In the above apparatus, the sheet is first illuminated with stimulating rays to emit light therefrom, thereby photoelectrically reading the light to produce radiation image information. Erasing light is applied to the sheet from which the radiation image information has been read to erase remaining radiation image information as the sheet is read by the reading unit. The light-intransmissive device prevents the erasing light from entering into the reading unit.
