Sep 13, 1994

Appl. No.:

8/305153

Inventors:

Louis A. Lippincott - Roebling NJ

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H04N 5228

US Classification:

348222

Abstract:

A method and video camera for generating time varying video images.

Inventors:

Louis A. Lippincott - Roebling NJ

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G09G 506

US Classification:

345431

Abstract:

In the system of the present invention an individual displayed pixel is a weighted combination of a video pixel and a graphics pixel. For example, a pixel displayed on a monitor may be three-quarters graphics and one-quarter video. In this system a color lookup table providing a red, a green and a blue lookup table output value is extended to provide a further lookup table output value. The further lookup table output value is a weight value representative of the relative weights of a video pixel and a corresponding graphics pixel. The weight value is applied to a matrix multiplier which also receives video pixel information and graphics pixel information. The matrix multiplier determines a weighted combination of the video and graphics pixel information according to the weight value to provide a blended pixel. A YUV standard to RGB standard conversion matrix is provided within in order to receive video signals in a YUV format and apply the video signals to the matrix multiplier in an RGB format.

Abstract:

The reprogrammable RAM cartridge of the present invention is adapted for use as a reprogrammable video game. The cartridge uses an optoisolator connected in a circuit between the shield and ground lines to detect the presence of a signal indicating that the cartridge is in a programmer, rather than in a video game unit. While in the programmer, the program stored in the RAM can be changed. However, when removed from the programmer, the cartridge acts like a standard video game cartridge.

Inventors:

Louis A. Lippincott - Roebling NJ

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 1300

US Classification:

345508

Abstract:

Visual data in a first color format stored in first memory locations are merged with visual data in a second color format, which different from the first color format, stored in second memory locations to form a merged pixel stream. An analog signal is generated representative of the merged pixel stream. In a preferred embodiment, one set of visual data is graphics data in an 8-bit CLUT format and the other set is video data in an 8-bit packed YUV9 format (also known as the 4:1:1 format). In this embodiment, the video data is unpacked and chromakeying is applied to generate the merged pixel stream.

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H04N 530

US Classification:

348222

Abstract:

A method and video processing system for receiving and processing consecutive sets of video signals from a video camera. A first capture signal is transmitted to the video camera. A first set of one or more video frames is received from the video camera in response to the first capture signal. The first set of one or more video frames is processed by the video processing system.

Inventors:

Louis A. Lippincott - Roebling NJ

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H04N 5275

US Classification:

348592

Abstract:

A chroma keying device is provided for switching between graphics images and video images. An input signal and a reference are compared to provide a switching signal for performing the switching between graphics and video. A switching signal is provided when the input signal color information indicates that the input signal represents a true black image. Thus, switching is triggered upon black in the chroma keying device of a present invention. The black level is determined when each of the red, blue and green inputs of the device receives substantially zero current. A very sensitive comparison is performed between these input lines and a reference voltage in order to detect this condition. In the chroma keying device of the present invention, this sensitive comparison is accomplished using matched diodes within a common integrated circuit.

International Classification:

G06T 1100

US Classification:

Abstract:

A method and apparatus for processing signals for display using a single frame buffer. In a preferred embodiment, a plurality of pixels are received, wherein one or more of the plurality of pixels corresponds to a first display and one or more of the plurality of pixels corresponds to a second display. A display bit map and a display mask are generated in accordance with the plurality of pixels. If a pixel of the plurality of pixels corresponds to the first display and a corresponding mask field of the display mask has a first-display value, then the pixel is stored in the display bit map, wherein the mask field comprises at least one mask bit. Otherwise, if the pixel corresponds to a key color, then the mask field corresponding to the pixel is set to the first-display value. Otherwise, the pixel is stored in the display bit map and the mask field corresponding to the pixel is set to a second-display value.
