IMAGE PICKUP APPARATUS AND IMAGE PICKUP METHOD

摘要

An image pickup apparatus includes an image sensor that reads out an image in a time period Te, a mechanical shutter that opens and closes in a traveling time Tm that satisfies Te>Tm, a system control section that controls the mechanical shutter to set a time period from opening to closing of the mechanical shutter to T1 and causes the image sensor to continuously read out images of a plurality of frames in a time period T2 that satisfies T1>T2, and an image combining section that generates a combined image from the images of the plurality of frames. The system control section performs control to fully read out electric charges exposed in any pixel in the time period T1.

主权项

1. An image pickup apparatus comprising:
an image pickup device configured to receive an object light image in a plurality of two-dimensionally arrayed pixels, generate image data, and read out the image data in a readout time Te; a mechanical shutter disposed on a front surface of the image pickup device and configured to control an exposure time of the image pickup device according to opening and closing actions in a traveling time Tm that satisfies Te>Tm; a control section configured to control the mechanical shutter to set a total exposure time from opening to closing of the mechanical shutter to T1 and control, with an electronic shutter, the image pickup device to continuously read out image data of a plurality of frames in a one-frame exposure time T2 that satisfies T1>T2; and an image combining section configured to combine the image data of the plurality of frames to generate combined image data of at least one frame, wherein the control section performs control to fully read out electric charges exposed in any pixel in the total exposure time T1.
