Image signal generating device e.g. graphic card, testing method for computer, involves comparing test image data with created and outputted image data by device, and determining test results based on comparison result

摘要

The method involves providing test image data to an image signal generating device (5), and outputting image signals generated by the generating device. The generated image signals are transmitted to a device (10) that is arranged in such a manner that the image data is created from the image signals and is outputted. The created and outputted image data is read by the device. The provided test image data is compared with the created image data. Test results are determined based on the comparison result. Independent claims are also included for the following: (1) a device for creating image data from image signals (2) a computer program product with program code for executing a method for testing an image signal generating device (3) a testing system for testing an image signal generating device (4) a manufacturing method for a computer with an image signal generating device.
