Benefits of technology

The patent text describes a system and method for combining image data from multiple cameras. The system includes multiple image sensors that are synchronized using a common control signal. The image data from each sensor is combined to create a synchronized data line, which is then processed by an image signal processor and output to a display. The technical effect of this invention is that it allows for seamless synchronization and processing of image data from multiple cameras, resulting in improved image quality and a more realistic and immersive viewing experience.

Problems solved by technology

Combining image data from each of the sensors typically involves performing frame synchronization and line synchronization, which may result in synchronization and alignment challenges.
In addition, filtering of image data from multiple sensors and interleaving such image data may be further complicated when source sensors provide data at different frequencies or phases.

embodiment 300

[0062]The image signal processor 208 is configured to process the line data 218 and to generate processed line data 240. In a particular embodiment, the processed line data 240 may be provided as processed frame data. While two sensors have been shown, it should be understood that other embodiments may include more than two sensors. For example, FIG. 3 depicts an embodiment 300 that includes more than two sensors. An Nth sensor 305 is configured to generate an Nth data stream, illustrated as an Nth image data stream 315. The Nth image data stream 315 includes an Nth data line 325. The Nth sensor 305 may be substantially similar to the first and second image sensors 202, 204 and may receive the common control signal 234 from the sensor synchronizer 230, enabling the first, second, and Nth sensors 202, 204, 305 to generate closely aligned data streams 212, 214, 315. For example, the data streams 212, 214, 315 may have substantially the same timing characteristics, such as frequency an...

second embodiment

[0085]Referring to FIG. 7, a diagrammatic representation of a first data stream at an output of a first image sensor and a second data stream at an output of a second image sensor being combined to form a synchronized data line is depicted and generally designated as 700. A first sensor, such as the first image sensor 202 of FIG. 2, generates a first data stream 702 that corresponds to first image data of an image. A second sensor, such as the second image sensor 204 of FIG. 2, generates a second data stream 704 that corresponds to second image data of the image. Data from the first data stream 702 and data from the second data stream 704 are combined to form a data out data stream 706.

[0086]In a particular embodiment, the first data stream 702 includes data associated with a first line of the first image data of the image and the second data stream 704 includes data associated with a corresponding line of the second image data of the image. The first data stream 702 includes line d...

first embodiment

[0091]Referring to FIG. 8, a diagrammatic representation of a phase diagram illustrating a two line phase difference between a first data stream from a first sensor and a second data stream from a second sensor is depicted and generally designated 800. A first sensor, such as the first sensor 202 of FIG. 2, generates a first data stream that includes first sensor first line data 802, first sensor second line data 804, and first sensor third line data 806. A second sensor, such as the second sensor 204 of FIG. 2, generates a second data stream that includes second sensor first line data 812, second sensor second line data 814, and second sensor third line data 816. Data from the first data stream and data from the second data stream are combined to form a combined line 820. In the particular embodiment illustrated in FIG. 8, first, second and third line data is illustrated. Alternatively, any number of line data may be generated (e.g., 720 lines as illustrated in FIGS. 6 and 7).
