摘要： PURPOSE:To remotely control a title inserting function by using a wireless remote controller or the like and to improve the operability of the camera with integrated VTR by providing a memory for incorporating pictographs to display titles. CONSTITUTION:A title switching signal is transmitted from a wireless remote control part 1, and the signal is received by a reception part 8 inside the main body of the camera. Only a pair of a title character and a voice stored in a ROM titler IC 9 is called from the received signal and sent to a title adder circuit 10. Video signals outputted from a camera part 11 or VTR part 12 are respectively processed at a video processing circuit 13, added with title signals at the title adder circuit 10 and outputted to a monitoring screen. When it is suddenly requested during photographing to insert the title or it is requested at a position where a photographer is away from the main body of the camera during photographing to insert the title, the desired title can be instantaneously projected by operating the title remote controller with one hand.

摘要： PURPOSE:To facilitate the formation of a title image, etc., by specifying starting and finishing positions on a superposing and recording tape with the value of a tape counter and selecting a character, a picture, etc., from a previously prepared image library. CONSTITUTION:The traveling quantity of a tape is calculated in the units of hours, minutes and seconds based on a microprocessor PC 11 or a CTL signal and a reel pulse and the information of a counter is formed. Thus, information as to the starting and finishing positions for superposing and recording a title in image is made into the information of the counter, it is stored in the PC 11 and superposing and recording are started and finished by making the value of the counter at the time of edition coincidnt with the stored one of the counter. A video signal from the outside supplied to synthesic circuits 18 and 19 via an input section 20 and the title image read out from a memory 10 by a titler circuit 9 is synchronized horizontally and vertically with a color phase and inserted as a composite picture.

摘要： PURPOSE:To prevent an unrecorded part (blank part) from being left by detecting the tail of a recorded part on a video tape before recording is started and holding the camera in a recording temporary stop state at the part. CONSTITUTION:A reproduced FM signal which is picked up by a video head 2 from the video tape 1 is amplified by a preamplifier 3, inputted to a comparator 6 through a detector 4 and a low-pass filter 5, and compared with a previously set voltage 7. Consequently, the comparator 6 outputs 'Lo' when the reproduced FM signal is larger than the voltage 7 or 'Hi' when not. The output of this comparator 6 is inputted to a servo part 9 through a microcomputer 8 for control. Then the tape is rewound by searching until the output of the comparator 6 becomes 'Hi' when 'Lo' or 'Lo' when 'Hi', and the camera is switched to a recording stand-by state at this time.

摘要： PURPOSE:To prevent such a case where the images are continuously recorded with lack of a subject by stopping automatically and temporarily the recording when the subject disappears out of a camera integrated with a VTR. CONSTITUTION:A variable resistor is provided at the periphery of a focusing ring 4 of a camera integrated with a VTR so that the resistance value varies in response to the ring 4. The varied resistance value is read to calculate the distance from a subject. This distance is compared with a distance range inputted previously for the desired recording. Then the camera is automatically set in a recording mode only when the subject is included in the desired distance range. Thus it is possible to automatically record the images only when the subject is included in the camera screen even when the subject is included or not included in the screen or moving.

摘要： PURPOSE:To adsorb the dispersion of the delaying time of 1 horizontal scanning period delaying circuit at a tandem filter. CONSTITUTION:In a tandem filter, 1 horizontal scanning period delaying circuit is constituted of a fixed delaying circuit 1 and a variable delaying circuit 2. By a first synchronization separating circuit 4 to separate the synchronizing signal of an input video signal, a second synchronization separating circuit 5 to separate the synchronizing signal of the 1-horizontal scanning delayed video signal, a phase detecting circuit 6 to detect the phase shift of two synchronizing signals and the output signal of the phase detecting circuit, so as to make equal the 1-horizontal scanning period of the input video signal and the delaying time of the 1-horizontal scanning period delaying circuit, the delaying time of the variable delaying circuit is controlled. In order to make always equal the 1-horizontal scanning period of the input video signal and the delaying time due to the 1-horizontal scanning period delaying circuit, the adjustment of the delaying time is simplified and the tandem characteristics are improved.

摘要： PROBLEM TO BE SOLVED: To easily know the recorded content in record information sections by showing a list of set picture codes in a record reservation information when booking the recording and inputting program category information. SOLUTION: About each recording booking and each picture recording program category picture codes are set to support the identification of their contents, a plurality of kinds of category picture codes are stored in a memory 18 and set (attached) to each recording program. In booking, a picture code suited to the program among the picture codes in a program category information memory 17 is set to book the recording. Using this identifying means, recording characteristics suited to the program are set by recording characteristics switch circuit 49. For recording e.g. a movie program, a picture code corresponding to the movie is set to send information indicating the recording of the movie program to the recording characteristic switch circuit 49, thereby recording with the movie recording characteristics set to frequency characteristics suited for the movie easy to see and with characteristics set to enhance the high and low frequency bands of voice.
