    Abstract: An error voltage which includes serious fluctuation due to noise is applied to a LPF, and high frequency component due to noise is removed. The error voltage supplied through the LPF and a reference level, for example, 0-level voltage are supplied to a comparator. The comparator compares magnitude of theses two voltage each other, and outputs a signal which indicates polarity corresponding to the comparison result. As described herein above, by removing high frequency component included in the error voltage to be supplied to the comparator with the LPF, the polarity signal with reduced fluctuation due to noise and good quality can be obtained. Thus the polarity of an error voltage for controlling rotation of a disc can be judged correctly.

    Abstract: AN ERROR VOLTAGE WHICH INCLUDES SERIOUS FLUCTUATION DUE TO NOISE IS APPLIED TO A LPF (31), AND HIGH FREQUENCY COMPONENT DUE TO NOISE IS REMOVED. THE ERROR VOLTAGE SUPPLIED THROUGH THE LPF (31) AND A REFERENCE LEVEL, FOR EXAMPLE, O-LEVEL VOLTAGE ARE SUPPLIED TO A COMPARATOR (32). THE COMPARATOR COMPARES MAGNITUDE OF THESES TWO VOLTAGE EACH OTHER, AND OUTPUTS A SIGNAL WHICH INDICATES POLARITY CORRESPONDING TO THE COMPARISON RESULT. AS DESCRIBED HEREIN ABOVE, BY REMOVING HIGH FREQUENCY COMPONENT INCLUDED IN THE ERROR VOLTAGE TO BE SUPPLIED TO THE COMPARATOR (32) WITH THE LPF (31), THE POLARITY SIGNAL WITH REDUCED FLUCTUATION DUE TO NOISE AND GOOD QUALITY CAN BE OBTAINED. THUS THE POLARITY OF AN ERROR VOLTAGE FOR CONTROLLING ROTATION OF A DISC CAN BE JUDGED CORRECTLY.

    Abstract: When an interruption of a bus reset occurs in accordance with the IEEE1394 standard at the time of turn-on of a power source or the like, whether a loop connection has been made or not is discriminated. If it is determined that the loop connection has been made, "i.LINK NG" or "i.LINK LOOP" as a warning display showing that the loop connection has been made is displayed. By displaying such a warning, the user or the like can recognize the fact that the loop connection has been made. A measure for cancelling the loop connection can be performed. If it is determined that the loop connection is not performed, such a warning display is not performed but the ordinary operation according to the IEEE1394 standard is performed.

    Abstract: The present invention relates to an image information processing apparatus, an image capture apparatus, an image information processing method, and a program that allow a depth value to smoothly transition in a scene change of stereoscopic content. In a case where a rapid change occurs between a depth value 711 in an end portion of a chapter #i and a depth value 714 in a start portion of a chapter #(i+1), entire depth values are temporarily corrected to zero (infinity) on the occasion of the change between the chapters #i and #(i+1). On this occasion, a depth value is allowed to transition for a period of time of, for example, 0.5 seconds or longer. An original depth value 721 in the end portion of the chapter #i is allowed to sequentially transition so that a depth value 722 of the end frame becomes zero. Similarly, a depth value 723 of the start frame in the chapter #(i+1) is set to zero, and is allowed to sequentially transition to an original depth value 724 in the start portion.
