Abstract
A compositor selects a subset of image layers from a plurality of image layers with which to form an intermediate image. The compositor forms a resultant image from an intermediate image and one or more remaining image layers.
Claims20
A compositor comprising:
- a sorter configured to sort a plurality of image layers based on update information thereof and select first and second image layers according to a result of sorting the first to third image layers;
- and
- an intermediate image generator configured to generate an intermediate image by performing composition on the selected first and second image layers.
A system-on-chip (SoC) comprising:
- a compositor configured to sort a plurality of image layers based on update information thereof, select a subset of the layers according to a result of sorting the image layers, generate an intermediate image by performing composition on the selected image layers, and generate a resultant image by performing composition on the intermediate image and a remaining image layer;
- and
- a memory configured to store the resultant image generated by the compositor.
15-25. (canceled)
An apparatus, comprising:
- a processor configured to receive a plurality of image layers;
- the processor configured to composite a subset of the plurality of image layers to form an intermediate image;
- and
- the processor configured to composite the intermediate image and a remaining image layer to form a resultant image frame.
