- the main content display control unit 1801 renders the free viewpoint video at the switching destination based on the set sensation size (for example, the height of the viewpoint position and the eye width), and the sensation size of the free viewpoint space is rendered. Make the scenery according to the.
- FIG. 20 summarizes the filtering conditions.
- the filtering conditions are roughly classified into three types of filtering conditions: a filter based on information in the screen, a filter based on viewers, and a filter based on viewing conditions.
- the filter based on the information in the screen determines whether or not to select a sub-content depending on whether or not a certain feature point or object (for example, the face of member A of the idol group) is included in the screen.
- a certain feature point or object for example, the face of member A of the idol group
- the filter by the viewer uses the log of the viewer who is currently viewing the main content or the log other than the viewer as a filter.
- a filter based on viewer attributes is used.
- the attributes mentioned here include friends, acquaintances, social graphs / experts, viewing history such as watching similar works, viewing logs in the main content (tend to see the same object), etc.
- Profile information such as age and gender.
- Filters based on viewing status include viewing time zone, location / region, type and size of viewing device.
- FIG. 21 is a flowchart showing the processing procedure for determining the playback position in the sub-contents, the display position of the omni window, and the display size, which is performed in step S1904 in the flowchart shown in FIG. Show.
- the viewing state of the main content is acquired (step S2101), and information and filters used for filtering for selecting the sub content are provisionally determined.
- step S2102 the viewing information and filter used for the next analysis are analyzed. decide.
- step S2103 the viewing information of the sub-content is analyzed (step S2103), and the viewing information associated with the content is analyzed based on the filter provisionally determined in step S2101. If it is valid, the filter and score (weight) are calculated. Determine.
- step S2103 based on the filter determined in step S2103, a score is assigned for each information, and a voting with a score (weight) is performed on the content space-time for each unit time, each unit space, and each unit field of view (step S2104).
- step S2104 the score distribution of the voting result in step S2104 is estimated spatially and temporally (step S2105).
- step S2106 the evaluation functions other than the constraint condition and the log are integrated (step S2106), and contraction for suppressing a rapid change from the main content to the sub-content or suppression by the evaluation function is performed.
- step S2107 the combination of the maximum score and the parameter in that case after the constraint is applied in step S2106 is calculated.
- the field of view (viewpoint position and line-of-sight direction) of the maximum score and the reproduction start time are extracted, and the display position and display size of the omni window are determined according to the viewing method (step S2108).
