Abstract: An image processing apparatus comprises: an input unit that inputs an image signal from an image sensor, the image sensor being capable of carrying out first readout control, in which each line in a first region is read out at a first timing, and second readout control, in which each line in a second region is read out at a second timing different from the first timing; an acquisition unit that acquires a shake amount from a shake detection unit at the first timing and the second timing; and a correction unit that corrects distortion in the image signal caused by the shake amount. The correction unit changes a correction amount used in the correction on the basis of a difference between the first timing and the second timing.

Abstract: An image pickup apparatus capable of performing proper image evaluation in photographing a moving image by changing the exposure condition. An image pickup unit picks up an image of an object and a driving unit drives a focus lens in an optical axis direction. A control circuit controls a focus state of the object by causing the driving unit to move the focus lens in the optical axis direction. A focus evaluation value is acquired from each image. The control circuit causes the image pickup unit to pick up images of a multistage exposure image group by changing exposure time, selects an image according to exposure time, updates a direction of driving the focus lens using the focus evaluation value acquired from the selected image, and causes the driving unit to move the focus lens in the updated driving direction.
Abstract translation: 一种摄像装置，其能够通过改变曝光条件来拍摄运动图像时进行适当的图像评估。 摄像单元拾取物体的图像，驱动单元沿光轴方向驱动聚焦透镜。 控制电路通过使驱动单元在光轴方向上移动聚焦透镜来控制对象的聚焦状态。 从每个图像获取焦点评估值。 控制电路使得图像拾取单元通过改变曝光时间来拾取多级曝光图像组的图像，根据曝光时间选择图像，使用从所选图像获取的聚焦评估值来更新驱动聚焦透镜的方向， 并使驱动单元在更新的行进方向上移动聚焦透镜。
