摘要: An image apparatus has a light-receiving section and light-blocking section. The receives light from an object to generate analog video signal. blocks the reference signals. signal is converted into digital signals are accumulated predetermined number of times accumulation starting point on scanning lines forming for specific period. averaged average A level adjusted based so that difference between becomes zero. decided as 2 n smaller than “m”, object. (m−2 )/2, “n” “m” being positive integers.
