摘要:
A computer, a power saving method and a method for reducing output current are disclosed. The computer includes a driving module, an application module, and a daemon module. The driving module initializes the web camera when the web camera connects to the computer. When the web camera outputs signals to the application module, a signal channel is established. The daemon module detects the signal channel. When the signal channel stops, the daemon module set the web camera into the standby mode through the driving module.
摘要:
A web camera suitable for capturing an image data and storing the image data in a portable storage device is provided. The web camera includes a photosensitive device, a processing chip, and a dynamic image processing chip. The photosensitive device is suitable for capturing the image data. The processing chip is coupled to the photosensitive device and is suitable for receiving the image data output by the photosensitive device. The dynamic image processing chip is coupled to the processing chip. When the image data is a dynamic image data, the dynamic image processing chip outputs a control signal to the processing chip, and the processing chip stores the image data into the portable storage device according to the control signal.
摘要:
A method for dynamically adjusting an image taken by a webcam. After providing a first threshold value, an environmental reference value is calculated according to an exposure time and an average brightness value. The environmental reference value is compared with the first threshold value to determine whether to enter a noise-reduction mode to reduce noises of the image.
