Image capturing apparatus and control method thereof

摄像装置及其控制方法

Abstract

According to this invention, even when an image capturing apparatus has a plurality of read modes, the frame rate can be prevented from decreasing in a high-resolution video photographing mode. The image capturing apparatus includes an image sensor and drive unit. The image sensor includes an effective image sensing area having a plurality of pixels at the center portion of the image sensor, and a light-shielded pixel area having a plurality of light-shielded pixels at the peripheral portion of the image sensor. The drive unit can drive the image sensor in a plurality of modes, and drives the image sensor such that the plurality of read modes are almost equal to the light-shielded pixel read time BL-MIN for reading pixel signals in the light-shielded pixel area.
本发明提供一种摄像装置及其控制方法。根据本发明,即使当摄像装置具有多个读取模式时,也可以在高分辨率视频拍摄模式中防止帧频减小。该摄像装置包括图像传感器和驱动单元。图像传感器包括:在图像传感器的中心部分具有多个像素的有效图像传感区;以及在图像传感器的外周部分具有多个被遮光的像素的遮光像素区。驱动单元可以以多个模式驱动图像传感器,使得多个读取模式近似与用于读取遮光像素区中的像素信号的遮光像素读取时间BL-MIN相等。
