A method and system for detecting short-term stress of a subject person and generating alerts in an indoor environment are disclosed. The system may receive data on the subject person's heart rate, galvanic skin response, and accelerometer movement from a wearable device, and also capture image frames through a camera. After that, the system may perform bio-signal analysis in accordance with the heart rate and the galvanic skin response data, and perform skeletal motion analysis in accordance with the image frames. Based on bio-signal index and skin conductance index generated from the bin-signal analysis and skeletal motion analysis respectively, the system may perform data fusion to determine the short-term stress.

A method of reducing power consumption in a liquid crystal display illuminated by a backlight device includes dimming the backlight and adjusting the intensity of the image to compensate for the dimmed backlight. A dimming factor for the backlight is based on a clipping point determining from the pixel intensity distribution of the image signal. The intensity of the image is adjusted based on the dimming factor, wherein a first tone mapping function is used to adjust pixel intensities below an intensity threshold and a second tone mapping function is used to adjust pixel intensities above the intensity threshold.

LCD backlight dimming, LCD/image signal compensation and method of controlling an LCD display

A method and apparatus for image enhancement in a display illuminated by a lighting device. Enhancement is via use of a non-linear mapping function. An illumination level for the lighting device is determined and used with the mapping function to find a compensation factor for each pixel of the image. The brightness property of each pixel is adjusted by its compensation factor.

A debinarizer and a hardware-based method for debinarizing a binary bit stream into symbols comprising predefined binary sequences are disclosed in which predefined binary sequences and their corresponding symbols are represented as tree structures. A binary sequence is debinarized by traversing one of the tree structures to determine a corresponding symbol. Similar tree structures may be combined to form a single tree structure. The tree structures may be implemented as a finite state machine.
