Abstract: An apparatus for improving decoding accuracy of an equalized signal having a direct current (DC) level obtained from an optical disk is provided. A Viterbi decoder is configured to decode the equalized signal and output a Viterbi-decoded signal. A DC controller is configured to adjust the DC level of the equalized signal such that the equalized signal with the adjusted DC level is decoded.

Abstract: The invention provides an optical measurement device for measuring light to be inspected. The optical measurement device comprises a light receiving module, a light splitting module, and a plurality of color filters. The light receiving module is used for converting the light to be inspected into a first parallel light. The light splitting module is used for splitting the first parallel light into a plurality of parallel lights to be inspected. Each color filter receives at least one of the plurality of parallel lights to be inspected. The plurality of parallel lights to be inspected filtered by the plurality of color filters are used to calculate tristimulus values in the CIE color space.
