Abstract

Provided is a moving image generation device, which is configured to: render a frame image including a plurality of image elements; output rendering position information specifying a rendering position within the frame image of a confidential element whose viewing is to be restricted among the plurality of image elements; and generate a moving image by using the frame image while performing display restriction processing on a target region within the frame image which is specified by the rendering position information.

Claims

1. A moving image generation device, comprising:

a rendering section for rendering a frame image including a plurality of image elements;

a rendering position information output section for outputting rendering position information specifying a rendering position within the frame image of a confidential element whose viewing is to be restricted among the plurality of image elements; and

a moving image generation section for simultaneously generating

a restricted moving image by using the frame image, and when generating the moving image, performing display restriction processing on a target region within the frame image which is specified by the rendering position information, and

an unrestricted moving image without the confidential element,

wherein the restricted moving image is transmitted to one or more restricted users,

wherein the unrestricted moving image is transmitted to one or more unrestricted users different from the one or more restricted users, and

wherein each frame image of the restricted moving image and each frame image of the unrestricted moving are generated at the same time.

2. The moving image generation device according to claim 1, further comprising an application execution section for executing an application program,

wherein the rendering position information output section receives a rendering instruction for the confidential element from the application execution section, specifies the rendering position of the confidential element based on details of the rendering instruction, and outputs a rendering command for the confidential element to the rendering section.

3. The moving image generation device according to claim 2, wherein the application execution section outputs the rendering command for an image element other than the confidential element among the plurality of image elements directly to the rendering section.

4. The moving image generation device according to claim 1, wherein as the display restriction processing, the moving image generation section causes a bit rate of the target region to be lower than a bit rate of a region other than the target region to perform encoding.

5. A moving image generation method, comprising:

rendering a frame image including a plurality of image elements;

outputting rendering position information specifying a rendering position within the frame image of a confidential element whose viewing is to be restricted among the plurality of image elements;

simultaneously generating a restricted moving image by using the frame image, and when generating the moving image, performing display restriction processing on a target region within the frame image which is specified by the rendering position information and an unrestricted moving image without the confidential element,

wherein each frame image of the restricted moving image and each frame image of the unrestricted moving image are generated at the same time;

transmitting the restricted moving image to one or more restricted users, and

transmitting the unrestricted moving image to one or more unrestricted users different from the one or more restricted users.

6. A non-transitory computer readable information storage medium having a program stored thereon, the program including instructions for causing a computer to execute the procedures of:

rendering a frame image including a plurality of image elements;

outputting rendering position information specifying a rendering position within the frame image of a confidential element whose viewing is to be restricted among the plurality of image elements;

simultaneously generating a restricted moving image by using the frame image, and when generating the moving image, performing display restriction processing on a target region within the frame image which is specified by the rendering position information and an unrestricted moving image without the confidential element,

wherein each frame of the restricted moving image and each frame image of the unrestricted moving image are generated at the same time;

transmitting the restricted moving image to one or more restricted users, and

transmitting the unrestricted moving image to one or more unrestricted users different from the one or more restricted users.
