20080143737, Jun 19, 2008

Filed:

Dec 12, 2007

Appl. No.:

11/955239

Inventors:

Steven Todd Weybrew - Portland OR, US
Simon Wilson - Dacono CO, US
Brian Ellis - San Diego CA, US

Assignee:

QUALCOMM INCORPORATED - San Diego CA

International Classification:

G09G 5/02

US Classification:

345592

Abstract:

An apparatus, method, and computer program product for applying transparency to a rendered surface. The apparatus comprises a graphics processor configured to render a surface, wherein a transparency parameter is associated with the surface, the transparency parameter defining a blending process. The apparatus further includes a display processor configured to blend the rendered surface in accordance with the transparency parameter. Preferably, the transparency parameter is an EGL surface attribute.

Inventors:

Steven Todd Weybrew - Portland OR, US
Brian Ellis - San Diego CA, US
Baback Elmieh - Carlsbad CA, US
Simon Wilson - Dacono CO, US

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

G09G 5/00

US Classification:

345630, 345629

Abstract:

In general, the present disclosure describes various techniques for overlaying or combining a set of rendered graphics surfaces onto a single graphics frame. One example device includes a first processor that selects a surface level for each of a plurality of rendered graphics surfaces prior to the device outputting any of the rendered graphics surfaces to a display. The device further includes a second processor that retrieves the rendered graphics surfaces, overlays the rendered graphics surfaces onto a graphics frame in accordance with each of the selected surface levels, and outputs the graphics frame to the display.

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

G09G 5/36

US Classification:

345548

Abstract:

In general, the present disclosure describes various techniques for providing multi-buffer support for off-screen surfaces in a graphics system. One example device includes one or more buffer areas and one or more processors. The one or more processors are configured to allocate multiple buffers within the buffer space that are all associated with an off-screen surface using in graphics processing. The one or more processors are further configured to identify a first buffer within the buffers as a write buffer for the off-screen surface and to further identify a second buffer within the buffers as a read buffer for the off-screen surface, such that information relating to the off-screen surface is written into the first buffer during a write operation and information relating to the off-screen surface is read out of the second buffer during a read operation.

International Classification:

G09G 5/02

US Classification:

345604, 345589, 345600

Abstract:

In general, the present disclosure describes various techniques for creation of surfaces using a platform interface layer wherein such surfaces may have different format layouts for various different color spaces, such as the YCbCr color space. One example device includes a storage device configured to contain surface information and one or more processors configured to create a graphics surface within a color space using a platform interface layer. The platform interface layer lies between a client rendering application program interface (API) and an underlying native platform rendering API. The one or more processors are further configured to specify a format layout of data associated with the surface within the color space using the platform interface layer and to store the format layout within the storage device. The format layout indicates a layout of one or more color components of the data associated with the surface within the color space.
