摘要： PROBLEM TO BE SOLVED: To solve defects such as freeze of an image and block noise when a non-standard signal is inputted to an image compression circuit in a MPEG encoder, etc.
SOLUTION: A time base correction circuit 15 stores an input signal to a memory 6 and reads the stored signal in timing delayed for a predetermined time from V synchronization of the input signal. The circuit 15 resets a reading synchronization generating circuit 9 at each input field. The reset location proceeds 3H or 10H from V synchronization for reading. The circuit 15 detects if the input signal is a non-interlaced signal and field length deviates from a standard value and then corrects odd or even order of a synchronization signal and timing of synchronization. If the input signal is a non-standard signal, the circuit 15 provides a switch 18 which can output without passing image compression circuits 16, 17.

摘要： PROBLEM TO BE SOLVED: To allow a display screen to optionally orient, relative to a frame, thus facilitating handling. SOLUTION: Fig.(a) is a state of photographing and Fig.(b) is a state of variously operating an operating key unit 16, allowing a display screen 15a to optionally orient, relative to the apparatus body 41, according to its operating mode. The body 41 has an camera lens 5 incorporated in a video camera on the side and a counter 6 composed of a light-emitting element array of a plurality of LEDs and the like around it. At a snap photograph mode with a predetermined photographing time, the light-emitting state of the light-emitting element array varies with the photographing time lapsed and this can be seen from the photographing side, to thereby sensually recognize the lapse of the photograph and the photograph remaining time.

摘要： PROBLEM TO BE SOLVED: To provide a TBC capable of operating even in a special reproduction mode and realizing an added V adjustment function in a still mode in particular. SOLUTION: As the first method, this processor resets a tsync phase at prescribed timing generated by delaying the timing from the V synchronous information of a regenerative signal in each field in order to correct the accumulation quantity of time base errors between an input signal and a tsync and can further change the V synchronous phase of a TBC output signal while linking with the change of an added V phase by using added V signal information instead of the V synchronous information of the regenerative signal. As the second method, the processor can realize the change of the V synchronous phase by providing a variable function at such a vertically synchronous timing position as corresponds to an added V in the TBC memory read control.

摘要： PROBLEM TO BE SOLVED: To provide a video signal processor which performs video signal processing responding to the field length of the video signal. SOLUTION: Input processing of a first inputted video signal is performed in an input processing circuit 6 to output the processed signal as a second video signal. A separation circuit 13 separates the synchronous signal of the second video signal. The field length of the second video signal is discriminated by a field length discriminant circuit 14 from the separated synchronous signal. The processing of the second video signal is operation controlled by an output means 15 using an operation mode based on a discrimination result of the field length discriminant circuit 14.

摘要： PROBLEM TO BE SOLVED: To solve a problem of a conventional video camera recorder or video recorder that may have often brought about coding noises if an image to be inputted or a target object of a camera reaches a certain degree of complexity. SOLUTION: A video compression coding means of the recording apparatus is provided with a means for displaying a fact of excess of a prescribed coding amount. A user can easily grasp a coding state with sense by employing the display means that varies the display depending on the complexity of an image received by the recording apparatus such that the display means displays the increased magnitude of the coding rate when the complexity of the image received by the recording apparatus is greater and on the contrary displays the decreased magnitude of the coding rate depending on the simplicity of the received image. Since the display means displays the varied magnitude of the coding rate depending on the complexity of the received image and the varied display color when the prescribed code amount is exceeded and the user can understand with sense that coding noises appear and coding with excellent performance is not executed, the user grasps it during recording and can avoid it when the user can adjust an object of the camera. Further, by displaying the remaining volume and the coding rate of the recording medium associated therewith, the decreasing pace of the remaining volume and the remaining time caused by recording may be notified to the user.
