Information processing apparatus, image processing system, and information processing method

Combined use of a recommended viewpoint and a free viewpoint is achieved without display of a position of the recommended viewpoint using a frame or the like. A detection unit detects a viewpoint position change instruction. An output unit outputs a part of an image to a display unit. In this case, an output range (an image range corresponding to a current viewpoint) is changed according to a viewpoint position change unit instruction after output of a recommended range such that the output range transits in a direction toward the recommended range on the basis of a predetermined condition. For example, the predetermined condition is deviation of the output range from the recommended range. Moreover, for example, a transition speed is controlled such that return to the recommended range is achieved faster as a positional difference between the output range and the recommended range becomes larger.

Image processing apparatus, image processing method, and program

A display apparatus () that is an example of an image processing apparatus includes: an output unit that outputs part of an image including recommended viewpoint information as a display image to a display unit; and a transition control unit that causes the display range of the image to shift, on the basis of the positional relationship between the viewpoint position corresponding to the display image output to the display unit and the viewpoint position corresponding to the recommended viewpoint information. The output unit outputs part of the image to the display unit, on the basis of the display range that has been made to shift.
