摘要： PROBLEM TO BE SOLVED: To provide an excellent operability to an operator by improving a displacement between a mask-displaying position and a privacy-protection region generated when a turntable with a monitoring camera mounted thereon is rapidly rotated, and arbitrarily varying the synthetic rate of an imaging signal in a region of privacy protection and a privacy masking signal on setting a privacy mask, in a masking for the privacy protection of the monitoring camera. SOLUTION: A newly corrected mask is produced from the calculated data of a mask position on displaying the mask, from angles in each of tops in a mask-setting coordinate stored when setting the mask, a distance of photographic subject, the pan and the tilt angle of a turntable, a focal distance, and a length in one pixel of a pickup device; and the calculated data of the mask positions on displaying the mask by the same procedure as before. The corrected mask is added to its moving direction for display. The operator can check the imaging signal simultaneously with the mask position by arbitrarily setting the synthetic rate when setting the privacy mask. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To speedily additionally photograph one more picture through the indication calling rephotographing when camera shaking occurs during photographing by providing an output means for calling rephotographing by issuing the alarm of camera shaking corresponding to the output of a vibration detecting means for detecting vibrations on the main body of a camera. SOLUTION: Vibration detectors 11 and 12 are provided for detecting the vertical and horizontal vibrations of the camera. Vibration detecting signals from the vibration detectors 11 and 12 are amplified by a vibrate signal amplifier 13 and fetched later into a CPU 14 of a DSP. On the assumption that a photographer presses a photograph button 18, in this case, the signal of that photographing ON is fetched into a main CPU 15 and while a digital signal processing IC (DSP) 5 fetches images, the CPU 14 of the DSP monitors the vibration detecting signals outputted from the vibration detectors 11 and 12. When vibrations caused by camera shaking are detected, these signals are sent to the main CPU 15 and the occurrence of camera shaking is displayed on a display device 17.

摘要： PROBLEM TO BE SOLVED: To reduce leakage of signals not selected into a selected signal by stopping an output signal of an image pickup element not selected in the case that any of output signals of a plurality of CCD image pickup elements is selected. SOLUTION: An output signal 5 of a CCD image pickup element 1 is fed to an input of a switch 3 and an output signal 6 of a CCD image pickup element 2 is fed to an input of a switch 4. Output sides of the switches 3, 4 are connected and either the output signal 5 or the output signal 6 is selected by switching selection signals 7, 8, and a selected output signal 9 is obtained. The selection signals 7, 8 are used to control continuity/interruption between switch input and output and to generate reset gate pulses 12, 13 of the CCD image pickup elements 1, 2. A drive state of the CCD image pickup elements 1, 2 is controlled based on the reset gate pulses 12, 13. Since its output signal is stopped when a CCD image pickup element is not selected, the output signal does not appear an input of the switch 3 or 4.

摘要： PROBLEM TO BE SOLVED: To provide a system whereby a battery charging operation is surely carried out even when a child or an elderly person possesses a mobile type slave unit and to provide a system whereby a sure contact can be obtained from the mobile unit for a response to an important and particular instruction such as tracing of missing people even when the residual capacity of battery is decreased.
SOLUTION: In the case that the charging of battery of the slave unit is not quickly executed even when the battery residual capacity of the slave unit is decreased, a master unit possessed by the parent displays the reduction of the battery residual capacity of the slave unit. Further, in the case that the battery residual capacity of the slave unit is decreased resulting in causing risk of arising hindrance to the operations, the master unit stores particular instruction contents to a nonvolatile memory in the slave unit or to a management server so that operations in response to the instruction can be carried out after the battery residual capacity is restored to a sufficient capacity. Thus, the parent can monitor the reduction in the battery residual capacity of the slave unit possessed by the children or the like to prevent a worn-out battery, and even when the battery residual capacity of the slave unit is deficient, the slave unit can respond to the particular important instruction after the restoration of the battery residual capacity.

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.

摘要： PROBLEM TO BE SOLVED: To make it possible to bring out a clear complexion color by holding white balance to a state several fields before when a color content difference between a maximum value and a minimum value of color contents between blocks exceeds a subject detected value and having an automatic white balancing function operate when the difference is equal to or below the subject detected value. SOLUTION: In an automatic white balancing function control device 6, a signal from a signal converter 3 is sectioned into several blocks as a photographed image and calculated. A way of sectioning the blocks can be freely changed. Then, automatic white balancing of a signal processing circuit 4 is controlled so that a difference between a block of the darkest color and a block of the lightest color is smaller than a set value (a subject detected value), the white balancing is executed and the white balance immediately before the value becomes large is fixed to the one when the difference in color darkness between the block of the darkest color and the block of the lightest color is larger than the subject detected value.

摘要： PROBLEM TO BE SOLVED: To improve the operating convenience by setting a channel on a sub-menu of a remote commander not depending on processing a main image outputted on the television receiver that incorporates two reception channel selection circuits. SOLUTION: A television signal from a 2nd reception channel selection circuit 8 is led to a television signal modulation circuit 9, where the signal is modulated and the modulated signal is sent from a remote commander television signal transmission section 10 to a remote commander 12. The signal is received by a remote commander television signal transmission section 13 in the remote commander 12 and a reception demodulation circuit 14 demodulates the signal. A remote commander image processing circuit 15 applies processing such as color demodulation to the television signal, separates a synchronizing signal from the received television signal and generates deflection pulse to allow a remote commander side video output section 16 to output a video image. A remote commander audio processing circuit 17 demodulates an audio signal modulated by an audio subscarrier led from the reception demodulation circuit 14 and a remote commander audio output section 18 to output a television audio signal.
