摘要： An audio data processor (120) performs a decoding process and a compression (encoding) process with respect to audio data in units of frames each containing a predetermined number of samples. The resultant encoded data is temporarily accumulated in an encoded data buffer (110). A song boundary detector (106) detects a frame boundary which should be used as a song boundary based on song position information corresponding to the audio data and feature information output from a feature extraction signal processor (107). A frame boundary divider (111) modifies the encoded data accumulated in the encoded data buffer so that a frame boundary of the encoded data matches the detected frame boundary.

摘要： The present invention provides a technique enabling the amount of time required to evaluate the light fastness of a liquid crystal panel to be shortened. A method of testing the light fastness of a liquid crystal panel comprising a pair of substrates and a liquid crystal layer interposed between the substrates comprises the steps of: irradiating a test subject area of the liquid crystal panel with a laser beam, with at least one of the wavelength, the irradiation energy, and the irradiation duration of the laser beam set as a variable parameter; irradiating the liquid crystal panel with an observation beam and detecting the condition of the observation beam after passing through the liquid crystal panel; and evaluating the light fastness of the liquid crystal panel on the basis of a difference in the condition of the observation beam corresponding to the setting of the variable parameter of the laser beam.
