A user monitoring system receives a first data stream from a first recording device and a second data stream from a second recording device. Each of the first data stream and the second data stream include data relating to an eye of the user. The first data stream and the second data stream overlap temporally. The system processes the first data stream to determine a first blink sequence of the user, processes the second data stream to determine a second blink sequence of the user, and compares the first blink sequence and the second blink sequence to detect a blink pattern present in both the first blink sequence and the second blink sequence. The system determines a temporal offset of the first data stream and the second data stream by comparing respective positions of the blink pattern in the first data stream and the second data stream.

The information processing apparatus obtains first viewpoint information for specifying a virtual viewpoint corresponding to a virtual viewpoint image and second viewpoint information representing a viewpoint of a first image capturing apparatus existing in an image capturing range of a second image capturing apparatus that is used for generating the virtual viewpoint image and performs control so that the image captured by the first image capturing apparatus is output in a case where a position of the first image capturing apparatus specified by the second viewpoint information is included in a field of view of the virtual viewpoint specified by the first viewpoint information.

In a three-dimensional image display method, a processor acquires first three-dimensional data and second three-dimensional data of a subject from a recording medium. The processor converts a first three-dimensional coordinate system of the first three-dimensional data and a second three-dimensional coordinate system of the second three-dimensional data into a three-dimensional common coordinate system on the basis of structure information related to a geometric structure of the subject. The processor displays an image of the first three-dimensional data in the common coordinate system and an image of the second three-dimensional data in the common coordinate system on a display.

An image processing apparatus obtains information that on a first video and a second video at least one of which is a captured video obtained by an image capturing apparatus, the information related to the first and second videos includes information on first and second viewpoints corresponding to the first and second videos of a same timing. The image processing apparatus, in a case where switching a video to be outputted from the first video to the second video, generates information on a virtual viewpoint corresponding to a period from an end of output of the first video until a start of output of the second video, based on the obtained information on the first viewpoint corresponding to the period and the obtained information on the second viewpoint corresponding to the period.
