The means 11a, 11b, and 11c of the mode controller 11 show some of the functions of the CPU of the mode controller 11.
[0016]
Next, the operation of the video printer of this embodiment will be described with reference to the flowchart of FIG. 3 and the operation explanatory diagram of FIG. It is assumed that a cassette tape (not shown) on which a video signal is recorded is loaded in the cassette storage section of the VTR 16. The normal running reproduction (FRD), fast forward (FF), rewind (REW), fast forward reproduction (CUE), rewind reproduction (REVIEW), stop (STOP), and pause of the cassette tape by the tape traveling drive unit 21 are performed. (PAUSE) and the like can be operated by an operator of the main body of the VTR 16 or an operator of a remote controller (not shown), and also controlled by an operation of an operator of the operation unit 12 of the printer 1 as described above. I'm used to getting it.
[0017]
Next, a multi-array reduced image mode (auto memory mode) by operating the operation unit 12 is selected. At this time, the cassette tape stored in the cassette storage section of the VTR 16 is assumed to be stopped at an arbitrary tape position. At this time, the position address (tape position signal) of the cassette tape obtained from the tape position signal generator 20 is supplied to the mode controller 11 as the address of the start position S (tape start position signal). The signal is stored in the signal storage / division position determining means 11b (step ST-1).
[0018]
The tape traveling drive control signal generating means 11a of the mode controller 11 automatically generates a fast-forward control signal for the tape traveling drive device 21 to quickly advance the cassette tape. {Step ST-2, FIG. (A / D converter) ｝. Then, when the cassette tape is wound up to near its end, the running of the cassette tape is stopped by the control of the system controller 19 of the VTR 16 on the tape running drive 21 (step ST-4). In this case, the fact that the cassette tape has been wound up to near its end is supplied from the system controller 19 to the mode controller 11, whereby the tape traveling drive control signal generating means 11a of the mode controller 11 transmits the tape traveling drive device. The cassette tape may be stopped by automatically generating a stop control signal for the cassette tape 21. Then, the tape position signal storage / division position determination of the mode controller 11 is performed by using the position address (tape position signal) of the cassette tape obtained from the tape position signal generator 20 as the address of the end position E (tape end position signal). It is stored in the means 11b (step ST-5).
[0019]
Thereafter, a tape rewinding control signal for the tape traveling driving device 21 is automatically generated from the tape traveling drive control signal generating means 11a of the mode controller 11, and the cassette tape is set in a rewinding state {step ST-6, FIG. 4 (tail)). Then, when the cassette tape is in the rewinding state near its start end, the traveling of the cassette tape is stopped by the control of the system controller 19 of the VTR 16 with respect to the tape traveling drive device 21 (step ST-8). In this case, the fact that the cassette tape has been wound up to near its end is supplied from the system controller 19 to the mode controller 11, whereby the tape traveling drive control signal generating means 11a of the mode controller 11 transmits the tape traveling drive device. The cassette tape may be stopped by automatically generating a stop control signal for the cassette tape 21.
[0020]
Next, the length between the start position address and the end position address stored therein or the time during steady running is divided into a plurality of M by the tape position signal storage / divided position determination storage means 11b of the mode controller 11. , M-1 divided positions S1 to S15 (FIG. 4) are determined (calculated) and stored (step ST-9). Here, M is 16, for example. Next, the tape traveling drive control signal generating means 11a of the mode controller 11 automatically generates a fast-forward control signal for the tape traveling drive device 21 to bring the cassette tape into the fast-forward state (FF or CUE state) {Step ST -10, FIG. 4 (C)).
[0021]
The tape position address (tape position signal) from the tape position signal generator 20 of the VTR 16 based on the start position address and the division position address stored in the tape position signal storage / division position determination storage means 11b of the mode controller 11. Is determined to be the address immediately before the start position address and the division position address (several seconds before) (step ST-11), and if YES, the tape travel drive control signal generation means 11a outputs the tape travel drive signal. A playback running control signal for the device 21 is automatically generated to put the cassette tape into a playback state {step ST-12, FIG. 4C}, and the tape position signal generator 20 of the VTR 16 is output by the tape position signal detecting means 11c. The tape position address (tape position signal) It is determined whether or not it is a position address. If YES, one frame or one field of the cassette tape video signal at the start position address or the division position address is stored in the frame memory 5 under the control of the memory controller 6. It is fetched and stored {FIG. 4 (data)}, and the signal is reduced to 1/16 (step ST-14).
[0022]
Then, one frame or one field of the video signal of the cassette tape at the (M-1) th, that is, the fifteenth division position address is fetched and stored in the frame memory 5, and the signal processing for reducing the signal to 1/16 is performed. It is determined by the determining means (not shown) of the mode controller 11 whether or not the processing has been completed. If NO, a series of operations of steps ST-10 to ST-14 is repeated. As shown in FIG. 5, the memory controller 6 arranges and processes the video signals stored in the frame memory 5 so that M, that is, 16 reduced images are arranged and printed in a 4 × 4 matrix. Then, the stored contents are read out and supplied to the line head 8 to perform the 4 × 5 yellow, zenta, and cyan mixed color printing. Is printed on the photographic paper 25 (step ST-16, FIG. 5). In this case, if a video signal is not recorded at the start position or the division position of the cassette tape by chance, the expected reduced image is not printed thereon.
