摘要： PURPOSE:To increase a processing speed, and to reduce a memory capacity, by generating the interpolation value of an interpolating point by adding a constant obtained from a memory, on a one preceding interpolation value at every interpolating point. CONSTITUTION:A subtraction circuit 11 operates the differential value of digital data. A ROM6 outputs an increment D multiplied by 1/N setting the differential value as an address at every interpolating point, and a ROM7 outputs the rate input pulse R of a binary rate multiplier BRM8 setting the differential value as the address. The BRM8 frequency-divides an input frequency, and through FFs 10 and 11, inputs an interpolation value correcting pulse CA to an adder circuit 4. The adder circuit 4 adds the increment D, and the pulse CA, on the interpolation value of the preceding interpolating point obtained from a latch circuit 9, and generates the interpolation value. A selector 5 selects the output of the circuit 4, and sends it to the circuit 9, then outputs an output H. In this way, the processing speed can be increased, and the capacity of the ROM can be reduced.

摘要： PURPOSE:To detect welded parts at a high accuracy by a method wherein output of an amplifier is memorized with invariable analog-digital conversion when reflected waves are attenuated most with the rotation of a steel pipe and determined to coincide with the value being memorized. CONSTITUTION:A steel pipe 1 is rotated with a turning roller control circuit 13. A signal received with a probe is amplified with an amplifier 8 and sent to a comparator 9 and an analog-digital converter 14. The signal is compared with a set value L by means of the comparator 9 and when the output of the amplifier 8 is below the set value, the analog-digital converter starts to work and the lowest value with a comparator 15 is latched with a latch 16. When the output of the amplifier 8 is larger than the set value L, the operation of the analog- digital converter 14 is stopped to halt the rotation of the steel pipe. Then, as the output of the amplifier 8 lowers below the set value L, with the rotation of the steel pipe 1 in the opposite direction, the analog-digital converter 14 is operated to allow a data coincidence detection circuit 17 to determine that the latch 16 coincides with the analog-digital converter 14 and a signal is outputted to stop the rotation of the steel pipe.

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.
