摘要:
A method and associated apparatus for detecting the amount, size, shape, and location of anomalies, such as dirt and scratches, on the surface of a test photographic element after the application of a cleaning procedure and for objectively determining the effectiveness of the film cleaning devices and procedures at removing dirt from photographic negatives and slides and the scanner's sensitivity to the artifacts on the test photographic element's surface. The test photographic element is scanned and the scanned image is digitized and converted to color digital count values. The count values are corrected for systematic errors and a set of context dependent threshold values on the corrected data is computed. If the corrected data passes any of the series of threshold tests it classified as anomalous otherwise it is considered to be background or clean. A series of statistics are calculated for the detected anomalies and are reported to the operator. This report enables the operator to monitor and maintain the quality of the cleaning process.
摘要:
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel. A replenishment pump calibration system is integrated into the processor so that no manual measurements or special tools are required to set replenishment solution rates.
摘要:
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel. The apparatus accurately maintains the processing solution level by keeping the upper surface of the processing solution below the high impingement devices solution exit.
摘要:
A low volume photographic material processing apparatus, that utilizes a plurality of processing modules, that have a narrow horizontal processing channel. The processing modules may be arranged in either a horizontal or a vertical direction to solve the space constraints and the rigidity of prior photographic processor designs.
摘要:
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. The channel is formed by a repeating combination of squeegee pinch rollers and impingement slot nozzles. Photographic processing solution is introduced through the impingement slot nozzles and the squeegee pinch rollers are used to remove the processing solution from the photosensitive material and provide transport of the photosensitive material. Solution level control is achieved by drains positioned below the tops of the upturned sections.

摘要:
A low volume photographic material processing apparatus that utilizes a tank having integral means through which processing solution is pumped and a rack which has integral means to facilitate its insertion and removal from the tank, the rack and the tank are relatively dimensioned so that a small volume for holding processing solution and photosensitive material is formed between the rack and the tank. The apparatus accurately maintains the processing solution level by keeping the upper surface of the processing solution below the high impingement devices solution exit.
摘要:
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. The channel is formed by a repeating combination of squeegee pinch rollers and impingement slot nozzles. Photographic processing solution is introduced into opposite ends of alternating impingement slot nozzles, having delivery channels and the squeegee pinch rollers are used to remove the processing solution from the photosensitive material and provide transport of the photosensitive material. Solution level control is achieved by drains positioned below the tops of the upturned sections. The slot nozzles and the pinch rollers work interactively to break down the chemical barrier layer.
摘要:
In a photographic film process after a film negative has been bleached, but before being fixed, an image of the negative is electrically captured. This captured image is used to determine if a print should be made.

A discrete micro continuous tone image provided on a photosensitive media, a product containing the micro discrete continuous tone image, and a method of making same. The micro discrete continuous tone image can be formed using near field optics which results in forming images of about 20 microns in size.
