Patent Images
1. An image processing apparatus comprising:
- a determination unit configured to determine an intermediate rendering size smaller than a display rendering size by using vector data and a frame rate of the vector data;
a generation unit configured to generate intermediate raster data by rendering at the intermediate rendering size determined by said determination unit; and
a scaling unit configured to scale up the intermediate raster data generated by said generation unit to the display rendering size,wherein said determination unit temporarily renders the vector data at a size smaller than the display rendering size, and determines the intermediate rendering size by using a temporary rendering result.

Abstract
An image processing apparatus capable of reducing frame loss and smoothly playing back vector data-based images is provided. A determination unit determines an intermediate rendering size smaller than a display rendering size by using vector data and its frame rate. A generation unit generates intermediate raster data by rendering at the intermediate rendering size determined by the determination unit. A scaling unit scales up the intermediate raster data generated by the generation unit to the display rendering size.

4. An image processing method comprising:
-
a determination step of determining an intermediate rendering size smaller than a display rendering size by using vector data and a frame rate of the vector data; a generation step of generating intermediate raster data by rendering at the intermediate rendering size determined in the determination step; and a scaling step of scaling up the intermediate raster data generated in the generation step to the display rendering size, wherein in the determination step, the vector data is temporarily rendered at a size smaller than the display rendering size, and the intermediate rendering size is determined by using a temporary rendering result. - View Dependent Claims (5, 6, 7)
