Abstract
Providing an image combination device and/or a display system comprising the same. The image combination device including an SGL control unit separating a plurality of layers into a first group layer and a second group layer not overlapping the first group layer, and a multi-layer blender combining the first group layer to produce a first composite image in a first frame and combining the second group layer including updated layers with the first composite image of the first frame to produce a second composite image in a second frame subsequent to the first frame.
Claims20
A display system, comprising:
- a processor configured to combine some layers of a plurality of layers to produce a first composite image and combine other layers of the plurality of layers to produce a second composite image;
- a memory storing the first composite image;
- and
- the processor includes,
- a multi-layer blender configured to receive the plurality of layers and output the first and second composite images,
- an sparse group layer (SGL) output unit configured to transmit the first composite image to the memory,
- a composite output unit configured to transmit the second composite image, and
- a SGL control unit configured to control the multi-layer blender, the SGL output unit and the composite output unit,
- wherein the processor is configured to produce the first composite image when any one of layers included in a first group layer is set by the SGL control unit in a first frame and is stored in the memory, and
- the processor is configured to produce the second composite image by using the first composite image stored in the memory when all of layers included in the first group layer are not updated in a second frame after the first frame.

An image combination device, comprising:
- a sparse group layer (SGL) control unit configured to separate a plurality of layers into a first layer group and a second layer group, the layers of the second layer group not including the layers of the first layer group;
- a multi-layer blender configured to combine the first layer group to produce a first composite image in a first frame and combine the second layer group including updated layers with the first composite image of the first frame to produce a second composite image in a second frame subsequent to the first frame;
- a memory configured to store the first composite image;
- a SGL output unit configured to receive the first composite image and transmit the received first composite image to the memory;
- and
- a composite output unit configured to receive the second composite image and transmit the received second composite image to an external device, wherein
- the first composite image is produced by combining at least two of the plurality of layers input to the multi-layer blender, and
- the second composite image is produced by combining all of the plurality of layers input to the multi-layer blender.

An image combination device, comprising:
- a layer receiving unit configured to receive a plurality of layers corresponding to a current frame;
- a sparse group layer (SGL) control unit configured to separate the plurality of layers into a first layer group and a second layer group, the layers in the second layer group not overlapping the layers in the first layer group, the SGL control unit including a sparse attribute register (SAR) configured to store update attribute information about the plurality of layers that are activated;
- a memory configured to store a first composite image of a frame prior to the current frame;
- a multi-layer blender configured to combine the first composite image transmitted from the memory with the second layer group to produce a second composite image;
- an SGL output unit configured to receive the first composite image and transmit the received first composite image to the memory;
- and
- a composite output unit configured to receive the second composite image and transmit the second composite image to an external device.
