  • Patent number: 8416253
    Abstract: When a processor, which transits from a first mode that causes a guest operating system to operate to a second mode that causes a virtual machine monitor managing the guest operating system to operate, when previously set transition condition is satisfied, transits to the second mode, a determining unit determines a cause or the transition. When it is determined that an execution of a process related to a completion of writing the image information in an image storage unit on the guest operating system is the cause, a detecting unit detects an updated portion representing an unmatched portion of the image information between before and after writing.

  • Publication number: 20130077878
    Abstract: According to one embodiment, an image relay apparatus includes a reception unit, a determination unit and a transmission unit. The reception unit receives compressed image data from a relay source apparatus. The determination unit determines whether or not the compressed image data is processable through a first path not involving decompression of the compressed image data, based on data on a relay destination apparatus. The transmission unit transfers, to the relay destination apparatus, either the compressed image data processed through the first path or recompressed image data obtained by processing the compressed image data through a second path involving decompression, drawing, and recompression of the compressed image data.

  • Patent number: 8401847
    Abstract: An unknown word is additionally registered in a speech recognition dictionary by utilizing a correction result, and a new pronunciation of the word that has been registered in a speech recognition dictionary is additionally registered in the speech recognition dictionary, thereby increasing the accuracy of speech recognition. The start time and finish time of each phoneme unit in speech data corresponding to each phoneme included in a phoneme sequence acquired by a phoneme sequence converting section 13 are added to the phoneme sequence. A phoneme sequence extracting section 15 extracts from the phoneme sequence a phoneme sequence portion composed of phonemes existing in a segment corresponding to the period from the start time to the finish time of the word segment of the word corrected by a word correcting section 9 and the extracted phoneme sequence portion is determined as the pronunciation of the corrected word.
