Abstract

A video display apparatus includes: an imager that captures a video of surroundings of a vehicle; a transparent display panel installed in a window glass of the vehicle; an identification unit that identifies, from the captured video, a visible range where a passenger views an outside as a range displayed on the transparent display panel; an operation unit that is operable on a surface of the transparent display panel; a recording controller that records the captured video in a storage; a replay controller that replays the recorded video; and a display controller that causes the transparent display panel to display a video of the identified range, wherein when operation is started, the replay controller causes the transparent display panel to display a video at a start of the operation, and when an operation direction is along a travelling direction, the replay controller replays, in a reverse direction, the recorded video.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a Continuation of PCT International Application No. PCT/JP2023/013943 filed on Apr. 4, 2023 which claims the benefit of priority from Japanese Patent Applications No. 2022-079448, No. 2022-079458, and No. 2022-079484, all filed on May 13, 2022, the entire contents of all of which are incorporated herein by reference. FIELD OF THE INVENTION The present application relates to a video display apparatus. BACKGROUND OF THE INVENTION A system that captures a video around a vehicle is put into practical use, and is used as, for example, a drive recorder. A video that is captured by the system as described above is temporarily recorded and thereafter overwritten with a new video unless the video is stored by event recording or the like. A technology for performing forward replay or reverse replay of a video by performing flick operation on a screen with reference to a vanishing point that serves as a reference point in the video of the drive recorder has been disclosed (for example, see Japanese Laid-open Patent Publication No. 2020-078083). In the technology disclosed in Japanese Laid-open Patent Publication No. 2020-078083, when a passenger of a vehicle is viewing surroundings of the vehicle while the vehicle is travelling, it is difficult to immediately check a video of a location that is passed by the vehicle by travelling.
