Embodiment approach 1

[0030] figure 1 It is a functional block diagram showing a schematic configuration of the image display device 1 according to Embodiment 1 of the present invention. Such as figure 1 As shown, the image generation device 1 has a screen change request unit 11, a control unit 12, data storage units 13, 14, 15, an animation data generation unit 16, a rendering unit 17, an OSD (On Screen Display) memory 18, and an image display unit. 19. The control unit 12, the animation data generation unit 16, and the rendering unit 17 constitute an image generation unit.

[0031] The screen change request unit 11 has a function of receiving, for example, input data based on key operations by the user or text data transferred from an external device (not shown). The screen change request unit 11 includes a key input device (such as a keyboard, a remote controller), a pointing device (such as a mouse), and an interface circuit having a communication function with an external device. The scree...

Embodiment approach 2

[0057] Next, Embodiment 2 of the present invention will be described. The basic configuration of the image display device according to Embodiment 2 is the same as that of the image generating device 1 according to Embodiment 1 described above. In Embodiment 2, the structure of the OSD memory 18 is Figure 10 The configurations shown in (A), (B), and (C). Such as Figure 10 As shown in (A), the OSD memory 18 of Embodiment 2 has a Figure 8 The first surface P shown in (A) to (C) A and side 2 P B The storage area of ​​the same storage area, and also has multiple faces P C ,P D , ... the storage area. These faces C ,P D , ... are areas for registering animation data and screen display lists in advance. For example, on these faces P C ,P D , ..., data for urgent special display, data that is frequently selected, or data that takes time to dynamically generate is developed in advance.

Abstract

Disclosed are a device and a method for image generation which can restrict the size of storage areas required to display animated images. In an image generation device (1), processing blocks (12, 16, 17), which form an image generation unit, acquire object data (130p) and a display operation pattern which should be applied to the object data (130p) from data storage units (13, 14) on the basis of specified screen configuration information (150i), and generate animated images from the object data (130p) on the basis of the object data (130p) and the display operation pattern.

Description

technical field [0001] The present invention relates to an image processing technique for generating animated images (moving images) using data in the form of vectors. Background technique [0002] Vector graphic data includes parameters representing information such as coordinates, color, size, and shape of the start point and end point of the curve to be displayed. Use these parameters to perform deformation processing such as zooming in, zooming out, or rotating the image, so high-quality rendering output can be obtained . In addition, since data in the vector format is smaller in data size than data in a raster format such as bitmap data (raster graphics data), it is suitable for displaying moving images. [0003] For example, Japanese Patent Application Laid-Open No. 2007-121758 (Patent Document 1) discloses a technique for generating moving images using vector graphics data. To realize the function of displaying different animation images for each scene screen, if ve...
