Title: Picture signal processing method
Inventor: MORI MASANORI
IPC: H04N1/40
Filed: 1987-12-17
Abstract: PURPOSE:To attain binarization processing with high picture quality by using a specific noise cut level, slicing a picture signal in preceding over blur correction processing, and eliminating noise included in white and balck background. CONSTITUTION:An image sensor 20 consists of a CCD line sensor or a CCD area sensor and is driven by a pulse supplied from a pulse circuit and outputs a picture signal (a).
