Information processing apparatus and information processing method and computer program

Abstract

The present invention relates to an information processing apparatus, an information processing method, and a computer program. Theinformation processing apparatus simultaneously displays video content obtained from two or more sources. In displaying video content obtained from two or more sources in parallel to each other or as superimposed on each other, an information processing apparatus normalizes each image by use of the information such as the scale of each image and the corresponding area thereof. In the normalization, image manipulation such as digital zooming for example is executed on digital images such as a still image and a moving image. If one of the images to be displayed in parallel to each other or as superimposed on each other is an image taken with a camera block, optical control such as panning, tilting, or zooming is executed on an actual camera.

Description

Technical field [0001] The present disclosure relates to an information processing device, an information processing method for the device, and a computer program, wherein the device has a display screen that is also used as an input block based on, for example, a touch panel. More specifically, the present disclosure relates to the following information processing apparatus, information processing method, and computer program, which are configured to allow two or more users to perform cooperative operations through a touch panel having a large screen commonly used by these users . Background technique [0002] Recently, tablet terminals have rapidly spread, and these tablet terminals each have a display screen that is also used as an input block based on, for example, a touch panel. The tablet terminal has an interface based on widgets and a desktop, and therefore it is easy for the user to intuitively understand the operation method, so that the user can use the tablet more ea...

AI Technical Summary

Problems solved by technology

If a touch area occupied by each user is set, and each user performs an operation on an object given operation authority within this area, it is difficult to realize a collaborative task

[0008] Furthermore, if the GUI (Graphical User Interface) displayed on the screen of the terminal is constant regardless of, for example, the user's distance or the user's state, there is a problem that, for example, for a user who is very far away from the screen, the screen displayed The information is too small to be understood, or for example, the amount of information displayed on the screen is too small although the user is close enough to the screen

Therefore, there is a problem that the size of the object to be displayed varies depending on the screen size and resolution (dpi)

[0010] Furthermore, in prior art display systems, concurrently or superimposed display of two or more items of video content from two or more sources on the screen may result in: The size relationship between images, resulting in varying sizes and positions of image areas, makes it difficult for users to see images

[0011] Furthermore, changing the orientation of the screen in a terminal with a swivel mechanism makes it difficult for the user to see the display, so the display must be rotated for optimal viewing by the user
