1. a biological information input media, is characterized in that, this biological information input media comprises:

  • Collecting biological feature information device (10,31), for reading the live body position relatively moving several topographies that gather continuously described live body position as biological information;

    Moving direction detector (11), for the described biological information gathering according to described collecting biological feature information device (10,31), detect the moving direction of described live body position with respect to described collecting biological feature information device (10,31);

    Coordinate transformation device (14), carries out coordinate transform for the described biological information that utilizes the y axle component of the described moving direction that described moving direction detector (11) detects to gather described collecting biological feature information device (10,31);

    Biological information display device (15,81), this biological information display device (15,81) is for showing the biological information that has carried out coordinate transform by described coordinate transformation device (14);

    AndMoving direction hunting zone reduction means (12), this moving direction hunting zone reduction means (12) is when being consecutively detected identical moving direction and registration higher than predetermined threshold when described moving direction detector (11), the preset range that moving direction hunting zone is narrowed down to the moving direction detecting described in comprising, described moving direction hunting zone is defined as the scope that described moving direction detector (11) detects described moving direction;

    Wherein, when described y axle component is during with respect to described biological information directed in orthogonal and direction upwards, described coordinate transformation device (14) is carried out coordinate transform by affined transformation, in described affined transformation, described biological information be rotated so that described y axle component with respect to postrotational biological information directed in orthogonal and downward direction, thereby in described biological information display device (15,81) the upper erect(ing) image that shows described biological information, andWherein, if following condition meets N time when above, described moving direction hunting zone reduction means (12) is dwindled described moving direction hunting zone, described condition be described moving direction remain unchanged and registration higher than described predetermined threshold,Wherein, this biological information input media also comprises the mobile pick-up unit (13) that stops, this moves and stops pick-up unit (13) stopping for detection of the movement at described live body position, wherein, in the time that described movement stops pick-up unit (13) and the stopping of movement at described live body position detected, stop inputting described biological informationWherein, if represent to stop matching degree (MAX_Cv) that the matching degree (MAX_CS) of coincidence degree of the image in monitoring range exceeded the coincidence degree that represents the image within the scope of moving speed estimation more than pre-determined number, mobile the stopping of movement that stops pick-up unit (13) and detect described live body position.
