With a total of 4 patents to his name, Suzuki's work has had a lasting impact on the industry.

Latest Patents

One of Suzuki's latest patents is a simulator for automatic photographic printing apparatus. This simulator is designed for use in an automatic photographic printing apparatus where a negative image carried by a color negative film is printed on photographic paper through a light source system that operates under automatic exposure control. The simulator features a CRT that displays a positive image corresponding to the negative image. It includes an inversion circuit that inverts the output from an image pickup device, allowing for the accurate display of the positive image. Additionally, the simulator has a first conversion circuit that compensates for differences in integrated density between the negative image and the photographic paper. A second conversion circuit is also included to equalize tristimulus values based on the emission spectral characteristics of the CRT and the dye absorption characteristics of the print. This innovation ensures that a positive image, identical to the intended print, is displayed on the CRT with high accuracy.

Another significant patent by Suzuki involves a method for dividing the density range of component dyes in color hard copy. This method ensures that the lightness of the gray scale in the color hard copy is equally divided according to the level number of quantized color image signals. The density range division is characterized by the equal division of lightness among the component dyes, enhancing the quality of color reproduction in printed materials.
