With a total of 4 patents to his name, Hongoh's work has had a considerable impact on the photography industry.
Latest Patents
One of Hongoh's latest patents is a distance measuring device for cameras. This innovative device features a distance measuring optical system unit equipped with light-emitting and light-receiving elements. The system is designed to rotate across the photographing screen, allowing for precise distance measurement. The optical system unit can be stopped within a predetermined measuring range, controlled by a cam driven by a DC motor. Additionally, the device allows for switching between multiple distance measuring object ranges, accommodating both many-point and one-point distance measurements.
Another significant patent involves a pulse light emission system controlled by a microcomputer. This system emits light towards a photographed object, with the reflected light being captured by a semiconductor optical position detector. The outputs from this detector are processed through detecting circuits that logarithmically transform the current outputs. A differential detecting circuit then calculates the distance measuring signal, which is further refined by correcting for external light interference.
