    Abstract: PROBLEM TO BE SOLVED: To provide a motor controller, a control method and a control program thereof which can control a rotating speed of a capstan motor with higher precision within a large range of rotating speed without large change in a circuit structure. SOLUTION: A rotation detector 20 outputs FG signals SFG1, SFG2 depending on the rotating speed of a capstan motor 10, and an A/D converter 30 converts such FG signals to digital signals. Thereafter, these digital signals are outputted to an angle detection circuit 40 to calculate angular information SA. A comparison circuit 70 generates a pulse signal SP depending on the FG signal. A rotation speed detector 56 of a microcomputer 50 detects the rotation speed of motor depending on the pulse signal SP, selects one of the angular information SA or pulse signal SP depending on the detected rotation speed, outputs the selected signal to a servo operation circuit 54 in order to calculate an error between the rotation speed and the target speed, and outputs an error signal SE. Therefore, a drive circuit 60 generates a drive signal SD depending on the error signal SE to drive the capstan motor 10.

    Abstract: PROBLEM TO BE SOLVED: To provide an imaging device that absorb a variation of an imaging optical system for capturing a left-eye image and an imaging optical system for capturing a right-eye image, and generate image data that allows displaying a stereoscopic image without a sense of discomfort, and to provide an autofocus method and a program.SOLUTION: A left-eye image imaging unit 31L converts a subject optical image formed via a left-eye imaging optical system 21L into an electric signal to generate an image signal for a left-eye captured image. A right-eye image imaging unit 31R converts a subject optical image formed via a right-eye imaging optical system 21R into an electric signal to generate an image signal for a right-eye captured image. A control unit 45 independently controls the left-eye imaging optical system 21L and the right-eye imaging optical system 21R, and individually performs focus adjustments for the left-eye captured image and the right-eye captured image. Even if the variation of in-focus lens positions in the imaging optical systems for the left-eye image and the right-eye image occurs, the variation is absorbed and the image data that allows displaying a stereoscopic image display without the sense of discomfort can be generated.
