摘要： PROBLEM TO BE SOLVED: To highly accurately set the optimal value of laser power when data are recorded in a high-density optical disk. SOLUTION: A test signal with erasing power Pe fixed and recording power Pw changed is recorded in an optical disk. The recorded signal is reproduced to obtain a β value indicating asymmetry of the reproduced signal with respect to each recording power. Optimal recording power Pwo is set from recording power where the obtained β value is a target β value. In this case, the fixed erasing power Pe records another test signal and is decided from the measurement result of a modulation degree M value or complies with strategy information predetermined for the optical disk. Alternatively, Pe≈0 is used as erasing power Pe irrespective of the optical disk. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To precisely adjust the focus of an image pickup device which uses an automatic stop through easy operation.
SOLUTION: When the image pickup device is placed in adjustment mode, the stop is opened (S1) and the shutter speed is automatically adjusted (S2). An operator switches a display of an image (S3 to S5), manually adjusts the view angle over look at the whole image, and manually adjusts the focus over a look at an enlarged image for focus adjustment. At this time, focusing can be achieved in a state of shallow depth of field with an open aperture, so the focus can accurately be adjusted. After the adjustment (S6), the stop is automatically controlled (S7) and the shutter speed is fixed (S8). Consequently, the device enters image pickup mode.

摘要： PROBLEM TO BE SOLVED: To enhance a deviation between a privacy protecting range and a mask display position caused when a turning base with a monitor camera fitted thereto is turned at a high speed in masking for protecting the privacy from infringement caused by the monitor camera and to provide convenience to an operator by optionally varying a composite ratio between a privacy mask signal and a video signal within the privacy protecting range at the time of setting of a privacy mask. SOLUTION: A new correction mask is generated on the basis of data for calculating a mask position at mask display from an angle of each apex of mask setting coordinates stored at the mask setting, a distance of an object, panning and tilt angles of the camera turning base, a focal distance, and a length of one pixel of an imaging element, and of data for calculating the mask position at the mask display resulting from the same arithmetic operation as that at a preceding time, and the correction mask is added to the mask in its traveling direction and the resulting mask is displayed. Further, optionally setting the composite ratio at setting of the privacy mask allows the operator to simultaneously confirm the video signal and the mask position at the setting.

摘要： PROBLEM TO BE SOLVED: To mask a privacy protection area wherein a monitor camera is directed almost directly below or above, and set a mask near the end of a screen having the large distortion of an image in masking the monitor camera for protecting privacy without deteriorating monitoring functions, and reduce calculation errors of a mask display due to the mounting position deviation of the camera on its rotating mount.
SOLUTION: In a mask setting, a panning and tilt angle at a mask-setting coordinate are calculated from the mask-setting coordinate, a panning and tile angle of a camera rotating mount, a focal length, an object distance, a distance from an imaging element 2 to a panning/tilt rotation center, and the pixel length of an imaging element 2, and stored together with the distance of the object. In a mask display, a mask position at the mask display is calculated from the stored panning and tilt angle at the mask setting coordinate, the object distance, the panning and tilt angle of the camera rotating mount, the focal length, the object distance, the distance from the imaging element 2 to the panning/tilt rotation center, and the pixel length of the imaging element 2. The mask position of an image signal is combined with other signals.
