Imaging apparatus adapted to perform normal imaging and high-speed imaging

摘要

An imaging apparatus includes an imaging unit having a discrete pixel structure that outputs directly signals of respective M sample points corresponding to M pixels per single frame for normal imaging and imaging at a first frame rate. The imaging unit adds signals of respective N pixels out of M pixels per single frame and outputs signals of M/N sample points (M and N are integers equal to or greater than 2) at each frame for high-speed imaging and imaging at a second frame rate greater than the first frame rate. An operation unit outputs directly output signals from the imaging unit for normal imaging and performs interpolation operations on the output signals from the imaging unit for interpolating signals of the (N−1) sample points between respective sample points to output interpolated signals of the M sample points for high-speed imaging.
