  • Patent number: 8872963
    Abstract: A lens drive unit drives a focus lens. An imaging element obtains an image signal. An evaluation value calculation unit calculates an AF evaluation value from the image signal read out based on an interlace system. A determination unit determines whether the continuous AF evaluation values have a distribution of continuous increases and decreases. If the AF evaluation values are determined to have the distribution of continuous increases and decreases, an in-focus position calculation unit calculates an in-focus position by obtaining an interpolation curve from an intermediate value of the AF evaluation values adjacent to each other, otherwise, calculates the in-focus position by obtaining an interpolation curve of the AF evaluation value. A control unit drives the focus lens to the in-focus position.

    Abstract: A game machine of playing a game is provided in which music unique to a character is generated as the character advances its morphologic changes. The game machine of the present invention obtains a morphology changing factor and changes a morphologic change status of a character. When the morphologic change status of the character satisfies any of the evolution requirements provided to the next evolution stage of the current character, the game machine sets the evolution morphology correlated to the evolution requirement as a character morphology. It also generates an evolution melody on the basis of the character melody for the character and a morphology melody which is a melody unique to the evolution morphology of the character, and sets the evolution melody generated as an advanced character melody.
