  • Patent number: 9478235
    Abstract: Up-sampler generates an up-sampled sound signal from the sound signal. From the up-sampled sound signal, odd-ordered high-harmonic generator generates an odd-ordered high-harmonic, and even-ordered high-harmonic generator generates an even-ordered high-harmonic. Vowel sound detector identifies whether or not the sound signal is vowel sound, and generates a first gain value and a second gain value. First gain controller amplifies or attenuates the odd-ordered high-harmonic based on the first gain value, and outputs the resultant odd-ordered high-harmonic. Second gain controller amplifies or attenuates the even-ordered high-harmonic based on the second gain value, and outputs the resultant even-ordered high-harmonic. Sound signal processing device adds the gain-adjusted odd-ordered high-harmonic and the gain-adjusted even-ordered high-harmonic to the up-sampled sound signal, and outputs the up-sampled sound signal having the high-harmonics added.

  • Publication number: 20160156862
    Abstract: The present disclosure relates to a solid-state image pickup device and an electronic apparatus capable of generating highly-accurate image pickup signals having a large dynamic range. Pixels each include a high-sensitivity pixel and a low-sensitivity pixel having a lower sensitivity than the high-sensitivity pixel. A control gate controls a potential of a photoelectric conversion device of the low-sensitivity pixel. The present disclosure is applicable to, for example, a CMOS image sensor that includes both the high-sensitivity pixel and the low-sensitivity pixel having a lower sensitivity than the high-sensitivity pixel and controls a potential of the photoelectric conversion device of the low-sensitivity pixel.

  • Patent number: 9245537
    Abstract: In a speech enhancement apparatus, a generator part generates a value representing likelihood of a consonant from an input audio signal, and a calculator part generates a consonant/vowel discriminating signal for discriminating a consonant portion and a vowel portion based on the generated value, detects a first signal level of the vowel portion and a second signal level of the consonant portion based on the audio signal and the consonant/vowel discriminating signal, and outputs a level-related signal. A determining part determines a gain coefficient that exceeds one when the second signal level is smaller than the first signal level based on the level-related signal so that the gain coefficient increases as the second signal level becomes smaller than the first signal level. A multiplier part multiplies the audio signal by the gain coefficient to output an audio signal having an emphasized consonant portion.
