Latest Patents

Among his latest innovations is an image processing apparatus that features a high gradation mode. This apparatus includes an input device that processes a digital input signal representing gradation. A timing signal generator produces a predetermined timing signal, while a delay device adjusts this timing signal based on the gradation expressed by the digital input signal. Additionally, a pulse width modulation signal generator creates a pulse width generation signal that corresponds to the gradation of the digital input signal. This technology allows for intermediate gradation control without the need for offset and gain adjustments typical of analog circuits. In one operational mode, a single dot corresponds to one pixel of the digital input signal, while in another mode, one dot corresponds to multiple pixels.

Another notable patent involves an image forming apparatus equipped with a digital modulator. This apparatus utilizes a first delay generation circuit that does not require high-frequency clocks to obtain a pixel formation start timing signal from a digital input signal. It also includes a second delay generation circuit for obtaining a pixel formation end timing signal, along with a unit that derives a pixel formation interval signal from the start and end timing signals.
