Animation controller, animation control method, program, and integrated circuit

Abstract

Provided is an animation controller which can limit degradation in the display quality of an entire animation and which performs animation as intended by the application developer. This animation controller (10) is provided with: a priority specification unit (11) for specifying the priority of each of a plurality of animation components by referencing component priority information (d2),an animation execution unit (14),a decision unit (12) for deciding whether or not the computational load required for an animation is greater than a first appropriate value,and a component controller (13) for changing control content for an animation of a component to be changed, which is an animation component having low priority, from first control content to second control content when it has been decided the computational load is greater than the first appropriate value. The animation execution unit (14) performs the animation of components to be changed, in accordance with the second control content. The animation execution unit (14) performs the animation of components not to be changed, in accordance with the first control content.

Description

technical field [0001] The present invention relates to a device and the like for controlling animation of images displayed on a display. Background technique [0002] Conventionally, in order to operate home appliances such as TVs, video, and DVD (Digital Versatile Disc) players (hereinafter referred to as devices), users have used a GUI (Graphical User Interface) that displays images for receiving the operations on a display such as a TV. , graphical user interface) application program (hereinafter referred to as program). Also, applications with animations are increasing now. The so-called animation means that the state of the animation part (such as at least one of position, size, shape, color, and transparency) changes little by little according to a certain time interval to display the animation part. The certain time interval is determined in advance according to the display, specifically, by the update rate of the display set on the display called the vertical sync...

AI Technical Summary

Problems solved by technology

[0015] However, in the animation control device of the aforementioned Patent Document 1, the overall display quality of the animation is degraded, and there is a problem that the animation desired by the application developer cannot be realized.

[0016] Specifically, in the animation control device of the aforementioned Patent Document 1, when the CPU usage rate is low, the animation is performed by the application, but when the CPU usage rate is high, the frame rate of the animation, that is, the rendering process of the animation is not changed according to the application. amount to keep the CPU usage down

At this time, the quality of the overall screen displayed by the application, that is, the animation quality of all the animation parts on the display is degraded, and the animation desired by the application developer is not performed.
