Abstract:
A luminance sensing system and method and a computer program product thereof are provided. The system includes: a first luminance sensing unit, arranged at a first position, and used for sensing a light ray luminance at the first position to generate a first illumination value; a second luminance sensing unit, arranged at a second position, having a displacement unit, and used for sensing a light ray luminance at the second position to generate a second illumination value; and a computing unit, electrically connected to the first luminance sensing unit, the displacement unit, and the second luminance sensing unit, and used for acquiring the first illumination value and the second illumination value, acquiring luminance range information by using the first illumination value, and determining whether the second illumination value conforms to the luminance range information, so as to decide whether to control the displacement unit to move.
Abstract:
A plant image capture device and a method thereof are provided. A first mirror is disposed at a side of an image measurement position, so as to generate an mirror image of a plant disposed on the image measurement position; a first image capture device obtains at least one image including a direct image and the first mirror image of the plant; an image processing module uses a frame of the first mirror as a feature, so as to divide the at least one image including the direct image and the first mirror image of the plant and obtain the direct image and the first mirror image of the plant; an operation processing module processes the mirror image of the plant, so as to obtain a first image of the plant.
Abstract:
A portable audio recording and playback system is provided. The portable audio recording and playback system can synchronously display the corresponding lyrics or character contents, and it also can selectively record user's voice or the mixed signal of the user's voice and a background music including music and a human voice of singer during playback. Or the volume of the human voice in the background music can be increased or decreased corresponding to that of the music and be outputted or repeatedly played with changing speech speed without the tone changed for achieving the effects of on-the-go vocal and/or music accompaniment, voice recording, and language learning with changing speech speed without the tone changed.
