摘要： PROBLEM TO BE SOLVED: To prevent defocus caused by fluctuations in each lens, by updating a temperature correction coefficient based on a difference between the positional information of a focus lens group obtained by an autofocus control operation and the positional information of the focus lens group, calculated during a preset operation, and by further correcting an amount of temperature correction by the use of the updated temperature correction coefficient.
SOLUTION: The tracking control device for the focus lenses includes a temperature detector 18 disposed near the lens group in order to detect the temperature of the environment. An amount of temperature correction for coping with fluctuations in each of the lenses is calculated from the positional information of a variator lens group 2, the positional information of the focus lens group 4 in a predetermined lens position corresponding to the amount of temperature correction obtained from the positional information of the focus lens group 4 and the information of the environmental temperature detector, and the positional information of the focus lens group obtained by the autofocus control during focusing. The amount of temperature correction, obtained from a stored zoom trace curve, is further corrected.

摘要： PURPOSE:To improve the convenience of the telephone set by the user by automating dialing when a time and a content of telephone dialing are decided in advance in the case of dialing. CONSTITUTION:Input data by a ten-key of a numeral entry device 8 are stored in a time storage device 2 as time data. When a dial destination setting button 12 is depressed, a dialing destination telephone number entry is awaited, When a voice signal is inputted from a receiver 10, voice data are stored in a voice storage device 6. When a set button 14 is finally depressed, a controller 4 enters a dialing wait state and a timer device 1 starts comparison between time data from a clock 3 with data of the storage device 2. When both data are coincident, that is, the setting time comes, the timer 1 outputs a dial start signal commanding the start of dialing to the controller 4. Upon the receipt of the dial start signal, the controller 4 calls a destination telephone number from the destination telephone number storage device 5 and makes dialing from a terminal 7.

摘要： PURPOSE:To clearly record two kinds of sounds in the case that two microphones as sound input devices are set so that their positions are close to each other and besides, their sound collecting parts are opposite to each other in a magnetic recording/ reproducing device provided with two systems of the sound input devices whose phase characteristics of amplifiers are opposite to each other. CONSTITUTION:The sound generated from the sound source 6 of a subject is collected from the microphone 1, and is inputted to the amplifier 3, and the sound generated from the sound source 7 of a cameraman is collected from the microphones 1, 2, and is inputted to the amplifiers 3, 4. The amplifiers 3, 4 amplify the sounds the microphones 1, 2 collect in a way that their phase characteristics are opposite to each other, and output them to an adder 8. The adder 8 adds properly the sound amplified by the amplifier 3 and the sound amplified by the amplifier 4, and eliminates the excessive sound having passed through the microphone 1 and the amplifier 3 from the original sound having passed through the microphone 2 and the amplifier 4. A block 5 executes recording processing, and at the time of reproduction, the sound generated from the sound source 6 of the subject and the sound generated from the sound source of the cameraman can be clearly heard.

摘要： PURPOSE:To surely execute tracking by incorporating an infrared-ray sensor capable of sensing infrared rays with limited wavelength generated from a human body in an image pickup device, calculating a signal expressing obtained direction and distance, the existence of a human, etc., by a microcomputer and automatically executing the ON/OFF of a power supply for the device and the setting of an angle and magnification. CONSTITUTION:A distance measuring part 16 executes the pulse driving of infrared rays with a fixed frequency band to emit infrared rays through a light emitting window 5 and inputs a signal returned after being reflected by a subject through a light receiving window 6. The measuring part 16 calculates a distance up to the subject by using a time difference between light emission and light reception and inputs the data of the distance to the microcomputer 13, which controls a zooming function 4 and a lens control part 14 for controlling a focus based upon the input data and rewrites set data on occasion in accordance with the movement of a human based upon a series of operation. Thus the tracking of photographing is automatically executed and the optimum viewing angle of a human displayed on a monitor 20 can be confirmed.

摘要： PURPOSE:To make a picture easy to see by providing an object position discriminating circuit and a date position setting circuit to automatically change the display position of the date so that the date does not overlap the object. CONSTITUTION:The video signal picked up by a video camera 1 is inputted to an object position discriminating circuit 2. The, circuit 2 discriminates between the object and a background and sends the information to a date position setting circuit 3. The circuit 3 automatically sets such position of the date based on information from the object position discriminating circuit 2 that the date does not overlap on the object, and the information is set to a date generating circuit 4. The circuit 4 sends a date signal at this position to a date adding circuit 5, and the date signal is added to the video signal to display the date at the position other than the object. As the result, satisfactory photographing is performed without overlap of the date on the object during photographing of the video camera.

摘要： PURPOSE:To eliminate the cable for peripheral equipment control signal transmission and the cable for peripheral equipment power and to facilitate the installation of a video camera system by overlapping a video signal from a video camera with the power/control signals of the video camera and the peripheral equipment so as to transmit them. CONSTITUTION:A peripheral equipment controller 15 compares user input with a peripheral equipment control state which is set, and recognizes the control state of the peripheral equipment. Corresponding variable DC power signals for the video camera and the peripheral equipment are outputted from a power source for video camera/peripheral equipment driving 2 by control through the power controller 5 of a power overlap adapter main body 1 in accordance with the recognized result. Then, an overlap signal 18 where the signal is overlapped with the control signal for video camera/peripheral equipment and the video signal from a video camera main body 7 is transferred between the main bodies 1 and 7 by one cable. Thus, the cable for peripheral equipment control signal transmission and the cable for peripheral equipment power become unnecessary, and the installation and alteration of the video camera system become easy.
