Latest Patents
One of Narita's latest patents is an apparatus and method for preparing index prints. This innovation effectively utilizes photographic paper by reading magnetic information in accordance with the feed of a negative film. The method allows for the selection of a relevant index format based on the number of photograph frames, determining an index print size that corresponds to the selected format. Each frame undergoes exposure processing to accumulate image data, which is then used to produce an index print in a size that corresponds to the number of frames.
Another significant patent involves a shading correction method for photographic printers. This method addresses light amount irregularities by exposing an image displayed on a two-dimensional display unit. An LED light source is activated with a predetermined driving voltage, and the image is exposed for a specific duration. The density at each pixel is measured, and the light transmittance correction amount is determined to ensure that the density conforms to a predetermined reference density. This innovation enhances the quality of photographic prints produced.
