摘要： A CPU of a controller of an imaging apparatus includes an imaging controller, a detection unit, and a focus adjustment unit. The imaging controller controls a readout operation of an image signal from an imaging element. The detection unit detects a target region of automatic focus control. The focus adjustment unit performs the automatic focus control based on the target region. In the readout operation, the imaging controller first thins out and reads out a signal for detection which is an image signal for detecting the target region, and reads out a residual image signal after an end of the thinning out and reading out.

摘要： An apparatus comprising a sensor capable of generating a signal pair used in focus detection. The apparatus obtains, based on a defocus amount obtained using the signal pair, a focus distance of a lens unit that is mounted to the apparatus and adjusts a focus distance of the lens unit based on the obtained focus distance. When the lens unit is a multi-scopic lens unit having a plurality of optical systems having different axes, the apparatus obtains the focus distance using an adjustment value obtained based on an axis position that is a position on the sensor through which an axis of the multi-scopic lens unit passes.

摘要： An error is reduced in phase difference detection of an imaging element including a phase difference pixel with an on-chip lens in common for a pair of pixels. The imaging element includes a pixel, an individual on-chip lens, a plurality of phase difference pixels, a common on-chip lens, and a pixel circuit. The individual on-chip lens individually collects incident light for each pixel. The phase difference pixels are arranged adjacent to each other to detect a phase difference. The common on-chip lens is arranged in common for the plurality of phase difference pixels and collects incident light in common. The pixel circuit is formed in a semiconductor substrate and generates an image signal on the basis of a transferred charge. Charge transfer units of the plurality of phase difference pixels are in a region between the common on-chip lens and the individual on-chip lens.

摘要： A method and device for predictive autofocus on an object are provided. The method includes capturing an image of a target object to be tracked by a user of camera of a device, selecting a region of interest (ROI) corresponding to a target point of the captured image of the target object, initializing a target object tracker via input of the selected ROI at i-th frame, where i=1, updating the target object tracker based on data at previous (i−1)th frame for i-th frame, where i>1, determining current camera lens position for the tracked target object at current frame, when the target object is out of the camera focus, determining disparity for the selected ROI at i-th frame from previously collected data defining dependence of distance between the target object and lens surface on the camera lens position, determining delta lens position to focus the camera on the target object as a function of disparity and current lens position or target object position in the frame by a computing unit, calculating predicted target object position and delta lens position for N future frames from coordinates of current ROI and current delta lens position, and providing predicted autofocus in real time.
