Abstract: A color-calibration system is provided, which includes a host, a reference display apparatus, and a display apparatus. The host calculates peak-intensity change rates relative to different gain values for blue, green, and red colors using a first spectrum and second spectrum of a first display panel of the reference display apparatus respectively in a first display mode and a second display mode. The host calculates peak-intensity ratios for blue, green, and red colors using the first spectrum and a third spectrum of the first display panel in a predetermined color-temperature display mode. The host calculates blue/green/red gains of a second display panel of the display apparatus using a fourth spectrum of the second display panel in the first display mode, the peak-intensity change rates, and peak-intensity ratios, so that the first display panel and the second display panel display a consistent color in the same predetermined color-temperature display mode.

Abstract: A method and a system for vision-based defect detection are proposed. The method includes the following steps. A test audio signal is outputted to a device-under-test (DUT), and a response signal of the DUT with respect to the test audio signal is received to generate a received audio signal. Signal processing is performed on the received audio signal to generate a spectrogram, and whether the DUT has an unacceptable defect with respect to the predefined auditory standard is determined by analyzing a distribution of signal strength according to the spectrogram.
