Latest Patents

One of his latest patents is the "Image Area Determining Apparatus." This apparatus acquires a multi-value image to determine whether an image signal belongs to a picture area or a character area. It includes a density detecting unit that checks if the density value of the multi-value image falls within a specific range. Additionally, a density variation amount detecting unit assesses whether the variation amount of the density value is below a preset threshold. The determining apparatus concludes that the multi-value image relates to a picture area when both conditions are met.

Another significant patent is the "Method for Automatically Transcribing Music and Apparatus Therefore." This system generates a musical score from an input acoustic signal, which may include vocal songs, humming, and music from instruments. The system extracts pitch and power information from the acoustic signal, corrects the pitch based on deviations from an absolute musical scale, and divides the signal into single-sound segments. It further determines the key, time, and tempo of the acoustic signal, compiling comprehensive musical score data.
