Abstract

[Problem] To enable prior confirmation of the imaging area after controlling the imaging direction and magnification of the imaging device. [Solution] The information processing device acquires an image from an imaging device whose imaging direction and imaging magnification can be changed, and accepts a user operation to change at least one of the imaging direction and imaging magnification of the imaging device. The information processing device also displays at least one of a first frame corresponding to a first region set according to the user operation, and a second frame corresponding to a second region based on the range in which the first region and the imaging direction and imaging magnification of the imaging device can be changed according to the user operation. In this case, if the first region and the second region coincide, the information processing device displays the first frame superimposed on the image, and if the first region and the second region do not coincide, it displays the first frame and the second frame superimposed on the image.

Description

This invention relates to information processing technology for controlling the display of images. In recent years, the use of systems that remotely control network-connected imaging devices in video production has increased. These systems are known to have a function that allows users to specify an arbitrary area on the image displayed on a terminal device, thereby controlling the imaging direction (pan and tilt) and magnification (zoom) of the imaging device so that the image corresponding to that specified area is displayed. In the following explanation, this function will be referred to as area zoom. In area zoom, if the user specifies an area outside the control range of the imaging direction and magnification of the imaging device, the specified area and the image captured after area zoom will not match, resulting in the capture of an area unintended by the user. In contrast, Patent Document 1 proposes a technology that displays a warning when a designated area is not within the camera's movable range and visible range during area zoom. Furthermore, Patent Document 2 discloses a technology that, in area zoom mode, notifies the user by changing the frame color or displaying an icon or message if the designated area is outside the camera's movable range and visible range.
