Title: The Innovations of Takuma Kodama
Introduction
Takuma Kodama is a notable inventor based in Kokubunji, Japan. He has made significant contributions to the field of television technology, particularly in the area of color television cameras. With a total of 3 patents to his name, his work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is a circuit for generating a signal for correcting registration in a color television camera. This digital registration circuit utilizes a multi-tube television camera, where correction quantities corresponding to positions on a target of an image pickup tube are stored in a digital memory. The digital signal for the correction quantity is read out from the digital memory and converted into an analog signal, which is then smoothed through a low-pass filter. The smoothed signal is sampled at a frequency higher than that of the correction quantities, and the resulting digital signals are applied to a shift register. The output from the adder is used for correcting registration, effectively preventing shading generation.
Another significant patent is for a television camera capable of correcting shadings caused by the digital registration faculty in a multi-tube type color television camera. This invention includes differentiating circuits that generate differentiated waves of correction waveforms for adjusting registration. Non-linear circuits process these differentiated waves, and their outputs control the gain of a video signal circuit, removing components responsible for shading from the video signal.
