Abstract: An image processing apparatus comprises a first processor that processes an image signal output from an image sensor; a second processor, connected in downstream of the first processor, that processes an image signal transferred from the first processor; and a controller that selects any of the first processor and the second processor to be used to perform a predetermined process on the image signal output from the image sensor based on a predetermined condition. The controller controls to stop an operation of the second processor in a case where the controller selects the first processor, the predetermined condition includes an instruction for live view display, and the controller selects the first processor in a case where the live view display is instructed.

Abstract: An image sensor outputs captured image data by discriminating whether to add a result of an imaging plane phase difference AF calculation to a top of the captured image data or whether to add the result to an end of the captured image data, thus reducing a time lag between exposure and focus position movement.

Abstract: An image pickup apparatus that makes it unnecessary to temporarily stop image pickup performed by an image pickup device to thereby improve operability of the image pickup apparatus, and achieves power saving. In an image pickup apparatus having an electronic viewfinder function, first image signals for live view are acquired by thinning read lines of an image pickup device, and second image signals for AF evaluation value calculation are acquired from the other read lines at a higher speed than the first image signals, for simultaneous output with the first image signals. Reading of the second image signals is started when the state of the object of image data changed or when one photographing mode is changed to another by a user's operation, and is terminated when a reading termination condition set in advance in association with the reading start condition is satisfied.

Abstract: An image capturing apparatus comprises an image sensor, a controller, and a signal processor. The image sensor includes pixels each having a photoelectric conversion element and a signal storing unit. When in a simple reproduction mode in which the image signals read out from the image sensor undergo simple reproduction, the controller stores, in the signal storing unit, image signals from all pixels output from the image sensor, converts the size of the image signals stored in the signal storing unit into a size for simple reproduction to transfer the image signals to the signal processor, and upon the simple reproduction starting, the image signals from all pixels stored in the signal storing unit are transferred to the signal processor.

Abstract: 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.
