Abstract: An exposure-control system and an associated exposure control method are provided. The exposure-control system includes: an image capturing unit configured to capture a long-exposure image and a short-exposure image with a first exposure value and a second exposure value, respectively; and a processor, configured to calculate histograms of the long-exposure image and the short-exposure image, and calculate an exposure ratio according to the calculated histograms, the first and second exposure values, wherein when the exposure ratio is smaller than a first threshold, the processor switches a current exposure mode to a low dynamic range mode. When the exposure ratio is larger than a second threshold, the processor switches the current exposure mode to a high dynamic range mode. When the exposure ratio is between the first threshold and the second threshold, the processor does not switch the current exposure mode.

Abstract: A head mounted system includes a physiological signal sensor, a signal processing circuit, a memory, an application processor, and an eyeglass frame. The physiological signal sensor monitors a physiological state to output a physiological signal. The signal processing circuit determines whether the physiological state is abnormal according to the physiological signal. When it is not abnormal, the signal processing circuit controls the physiological signal sensor to monitor the physiological state at a first monitoring frequency. When it is abnormal, the signal processing circuit outputs a warning signal, and controls the physiological signal sensor to monitor the physiological state at a second monitoring frequency greater than the first monitoring frequency. The application processor receives the warning signal and stores physiological data corresponding to the physiological signal in the memory. The eyeglass frame carries the first physiological signal sensor, the signal processing circuit, the memory, and the application processor.
