Image capturing apparatus having a γ-characteristic corrector and/or image geometric distortion correction

摘要: An image capturing apparatus capable of performing a suitable illuminance nonuniformity correction by setting γ-characteristic every block even in the case that size character projected on sensing surface changes according to an magnification, and extracting boundary area between white board portion background applying processing this during for picked image, representation such as characters drawn manner obtained is clear easy see suitably color capturing, detecting regularly reflected light with high accuracy can thereby securely prevent error obtaining low quality preventing flash-image under insufficient illumination effectively perform correction.
