Latest Patents

Among her latest inventions, Ishibashi developed a groundbreaking circuit for generating a signal that corrects registration in color television cameras. This digital registration circuit cleverly stores correction quantities corresponding to specific positions on the target of an image pickup tube in a digital memory. It efficiently converts the read-out digital signal into an analog form, which is then smoothed through a low-pass filter. The smoothed signal undergoes sampling at a frequency higher than the reading frequency, allowing for precision in correcting shading issues in images. Furthermore, her design includes a shift register that sequentially processes the output signal to enhance registration accuracy.

Another notable invention is her television camera, which effectively corrects shading caused by the digital registration faculty utilized in multi-tube type color cameras. This device employs differentiating circuits to produce correction waveforms, which are essential in adjusting registration and eliminating unwanted components that lead to image shading. Her inventions have paved the way for advancements in video technology, ensuring a higher quality of visual output.
