Title: Ken Tanabe: Innovator in Motor Control and Light Source Estimation
Introduction
Ken Tanabe is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the fields of motor control and light source estimation, holding a total of 14 patents. His innovative work has had a lasting impact on technology and engineering.
Latest Patents
One of his latest patents is a motor controller that includes a first control circuit, a second control circuit, a determination circuit, and a command circuit. The first control circuit outputs a first control value based on a rule base from a command value of an angular velocity and a measured value of an angular velocity. The second control circuit outputs a second control value based on a learned model from the command value of the angular velocity and the measured value of the angular velocity. The determination circuit determines a state based on at least the second control value. The command circuit acquires and outputs a control command value from the first control value and the second control value based on a result determined by the determination circuit.
Another notable patent is a light source estimating apparatus and image pickup apparatus. This apparatus has a sensitivity ratio spatial distribution calculating unit configured to extract a first color pixel and a second color pixel which have close spectral sensitivity and which have different sensor responses from a first picked up image captured with an image sensor under an arbitrary light source. It calculates a ratio between a signal value of the first color pixel and a signal value of the second color pixel to acquire a first sensitivity ratio spatial distribution. Additionally, a similarity determining unit estimates the type of the arbitrary light source based on similarity between a second sensitivity ratio spatial distribution group calculated using a second picked up image captured with the image sensor under a known light source and the first sensitivity ratio spatial distribution.
