    摘要: A recording and playback device having a recording and playback controller that determines a temperature of a recording and playback medium. The controller determines the temperature by finding a recording light intensity at which a duty ratio of a playback light signal matches a duty ratio of the data to be recorded and estimating the temperature based on the recording light intensity. The controller may also determine the temperature by measuring the temperature with a temperature sensor. Based on the temperature, the recording and playback device calculates a playback light intensity at which a temperature distribution remains constant in a portion of the recording and playback medium illuminated by a playback light having the playback light intensity when the temperature of the recording and playback medium changes. The recording and playback controller also adjusts the playback light intensity based on a linear velocity of the recording and playback medium.

    摘要: A camera is capable of both silver-halide shooting, through which object images are recorded on silver-halide film, and video shooting, although its distance measurement device is placed substantially in the same way and its mirror box has substantially the same size as in ordinary single-lens reflex cameras. In this camera, a pellicle mirror splits the light flux having passed through a taking lens into a first light flux and a second light flux, and a rotatable mirror switches the subsequent path of the second light flux between the optical path for a third light flux and the optical path for a fourth light flux. The pellicle mirror, through its light flux splitting function, directs the first light flux to a silver-halide shooting system, and directs the second light flux to the rotatable mirror. The rotatable mirror, through its optical path switching function, either directs the third light flux to an optical viewfinder system, or directs the fourth light flux to a video shooting system.

    摘要: The data containing reference data is transformed into signature data by a method which depends on a variable generated by the reference data, and the identification data is certified by inverse transformation of the signature data. The signature generating rule changes in dependence on the reference data, and it is therefore extremely difficult to analyze the signature generating rule from the medium or the card reader/writer so that the forgery or modification of magnetic or other data, which is otherwise easy to duplicate, can be made extremely difficult. Therefore, even when a reader is illicitly obtained, and analyzed, it is extremely difficult to estimate the signature generating rule as it owes to the difficulty of solving a set of multivariate simultaneous equations.
