ELECTRONIC PEN FOR CAPTURING AN IMAGE, AND METHOD THEREOF

摘要

PURPOSE: An image acquisition electronic pen and an image acquisition method thereof are provided to acquire an image using a single LED light emission operation for each line in an image frame. CONSTITUTION: An LED driving part(110) emits LED light when a vertical synchronization signal is created. The LED driving part operates an LED in order to maintain a photon charge quantity of a CMOS(Complementary Metal Oxide Semiconductor) image sensor until a next vertical synchronization signal is received. A controller controls an image acquisition process.
