IMAGE PROCESSING APPARATUS CAPABLE OF MOVIE RECORDING, IMAGE PICKUP APPARATUS, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM

摘要

An image processing apparatus that correctly acquires evaluation values when movie recording is performed at a fixed frame rate. A first readout unit reduces readout rows of an image pickup device, and acquires and outputs image data for movie recording from the reduced readout rows. A second readout unit acquires image data from readout rows that do not overlap with that by the first readout unit at higher rate than the first readout unit, and outputs the acquired image data simultaneously with the first readout unit. Whether a subject's state changes for both the image data acquired by the first and second readout units is determined. If it is determined that the subject's state in the image data acquired by the second readout unit is changed, a speed at which the second readout unit acquires image data is changed while the first readout unit maintains a fixed speed.

主权项

1. An image processing apparatus that controls driving of an image pickup device to record a movie, the image processing apparatus comprising:
a first readout unit configured to reduce readout rows of the image pickup device, and to acquire and output image data for movie recording from the reduced readout rows; a second readout unit configured to, in the image pickup device, acquire image data from readout rows that do not overlap with the readout rows read out by said first readout unit, at higher rate than said first readout unit, and output the acquired image data simultaneously with said first readout unit; a determination unit configured to determine whether a state of a subject changes or not, with respect to both the image data acquired by said first readout unit and the image data acquired by said second readout unit; and a changing unit configured to, if said determination unit determines that the state of the subject in the image data acquired by said second readout unit changes, change a speed at which said second readout unit acquires image data in accordance with the change in the state of the subject, while said first readout unit acquires image data at a fixed speed.
