With a total of 6 patents to his name, Tanaka's work has had a considerable impact on various applications.

Latest Patents

One of Tanaka's latest patents is a photodetector output circuit. This innovative circuit comprises a plurality of adjacent photodetectors grouped into pairs, which generate signals indicative of light levels. It includes a first shift register for receiving signals from the first photodetectors and a second shift register for the second photodetectors. The circuit also features sample and hold circuits that sample and hold outputs from the shift registers. A comparator processes these outputs to deliver signals when there is a significant difference in light levels, effectively filtering out gradual variations caused by shading.

Another significant invention is his autofocus system. This system detects the image definition of an object using image sensors positioned along the light path of an optical system. It converts these definitions into electric signals to control the image-forming position. The system utilizes multiple electric signals from both a main image sensor and at least one sub-image sensor, which are processed to produce a focus control signal. This allows for precise adjustments in the position of the image-forming optical system, enhancing the clarity of captured images.
