Latest Patents

One of Lee's latest patents is a fingerprint recognition integrated circuit and fingerprint recognition device. This device includes a display, a touch sensor panel (TSP) that senses touch, and a fingerprint recognition integrated circuit (FPIC) that scans fingerprints. The FPIC features a pixel with a photoelectric element that receives light reflected by the fingerprint, a low noise amplifier (LNA) that outputs a signal voltage by converting an electric charge from the photoelectric element, and an analog-to-digital converter (ADC) that transforms the signal voltage into a digital signal. The ADC is equipped with a variable reference voltage generator, a comparator for correlated double sampling, and a counter that outputs the digital signal by counting the comparison signal.

Another notable patent is a digital photographing apparatus and control method. This apparatus includes a position sensor that detects the position information of a lens unit and an optical driving processor that calculates movement position variations of the lens unit. The processor compares these variations with a reference movement position variation to ensure accurate focusing.
