The present invention provides an image display system in which images can be displayed at at least a predetermined framerate even with limited processor performance. The image display system having a head-mounted display capable of displaying a three-dimensional image, the image display system includes a selection unit for selecting a viewing object desired by a viewer from the three-dimensional image, a detection unit for detecting a part to view corresponding to the viewing object selected by the selection unit, and a resolution increasing unit for increasing a resolution of the part to view that has been detected, wherein the head-mounted display displays the three-dimensional image in which the resolution of the part to view has been increased at at least a predetermined framerate.

Image display system

An image capturing apparatus comprises an image sensor, a display, a processor; and a memory holding a program which makes the processor function as a focus detection unit for detecting a focus position of the imaging lens, an imaging control unit configured to carry out the focus bracketing, and a display control unit configured to cause the display device to display a guide indicating a first area and a second area before the focus bracketing is carried out, the first area being an area in which an object suitable for focus detection of the imaging lens by the focus detection unit is arranged, and the second area being an area in which an object suitable for a user to determine an image that is in focus is arranged.

Image capturing apparatus capable of highly-accurate autofocus calibration and control method thereof, and storage medium

An apparatus includes a sensor outputting a first signal having a parallax, an image sensor outputting a second signal having a parallax, at least one processor, and a memory holding a program which makes the processor function as an acquisition unit configured to acquire an adjustment value. The acquisition unit selects a mode from a plurality of modes and acquires the adjustment value in the selected mode, the plurality of modes including a first mode for acquiring the adjustment value based on the result of the focus detection which is based on the first signal and a second mode for acquiring the adjustment value by a method different from a method in the first mode based on the result of the focus detection based on the first signal and a result of the focus detection which is based on the second signal.

Image pickup apparatus having a function for adjusting a detected in-focus position and control method for image pickup apparatus

A pair of pupil regions of an exit pupil, through which light beams received by a pair of photoelectric conversion units included in a pixel portion of a first image sensor respectively pass, are overlapped. A pair of pupil regions of an exit pupil, through which light beams received by a pair of photoelectric conversion units included in a pixel portion of a second image sensor respectively pass, are overlapped. A second base length, which is a distance between centroids of the pair of pupil regions corresponding to the pair of photoelectric conversion units included in the pixel portion of the second image sensor, is longer than a first base length, which is a distance between centroids of the pair of pupil regions corresponding to the pair of photoelectric conversion units included in the pixel portion of the first image sensor.

Imaging apparatus with two image sensors

A focus detection apparatus includes a focus detection unit configured to detect a focus state in each of a plurality of focus detection regions, an acquisition unit configured to acquire an adjustment value used for adjustment of a detection result, for each of the focus detection regions, and a control unit configured to switch between a first mode and a second mode based on focus states detected in the focus detection regions. In the first mode, the acquisition unit acquires the adjustment values for the focus detection regions, based on a focus state in a specific first focus detection region. In the second mode, the acquisition unit acquires the adjustment value for each of the focus detection regions, based on a focus state detected in each of the focus detection regions.
