In addition, when you stop recording the data of one joint point to the recording/reproducing section a3 and create a joint screen by sensing the reproduction signal from the recording section a, please follow the above-mentioned mark (1) # Komoto. Joint 1
Point data may also be created.

Next, FIG. 2 is a block circuit diagram of a still image information reproduction system in the Kokagaru Eirin signal generator of the present invention.

The reproduced output from the recording reproduction unit aa, that is, still image information, is transferred to, for example, 16 frame image memories M1 to M, 4 and written in numbers as shown in FIG. 3(1)4.

Also, the above-mentioned joint 0 point data f(L,

The analog video signal is converted and output.

The address generator (7) is supplied with an address shift control signal, and as shown in Figure 3 (bl), the start address for reading is shifted by one line per frame. .

As a result, the explanatory area of the memory is gradually rubbed, for example, in Figure 4 a% b% C...
The image is shifted upward at a rate of 1 screen every 4 seconds, as in .

The address generating section (a) can be easily created using microcomputer software, but it can also be constructed using hardware as shown in FIG. Counter (c) & 41r2 in Figure 5! j-・For music..., data U1, U2, Us... of one point of top end of each image.

It is applied to the preset data input P8 of . . . and is loaded at the timing of ■/2. The counter @ (to) counts the horizontal synchronizing signal, and its output is stored as horizontal line address data in the memories M1, M2, M5... You will be given a number.

First, at the timing of the V/2 pulse, the Ml counter (
C) is loaded into the upper end seam data U1 as shown in FIG. 6, and its output is further loaded into the counter (C). The memory M1 is read out using the output address of this counter (c), and the address is led out to the outside via a changeover switch. When the output data of the counter (2) reaches the lower end joining point L1 of the first stroke P1, this is detected by the comparator, and the output is given to the enable power E of the horizontal line counter for M2, and the sixth As shown in FIG. C, the counter starts supplying addresses to the memory M2 from the upper end splicing point U2 of the second image P2. At the same time, a switching signal that is set at Ll and reset at synchronization (2) as shown in FIG.

In the next ■ synchronization, the memory output warps from M2 to Ml,
The even field screen of the first image gIP1 is played back, and then the address of M1 is set to the lower edge gauze point L1 of the first image P1.
When reaching ', the memory output is switched from M1 to M2f based on the switching signal shown in FIG. 6B. At this time, the address where the counter is generated is 2-'II P 2
1 point of upper end joint [J2/G completed.

At the next V/2 timing, the memory output is again Mlf
At the same time, the count value of the counter (c) is increased by one, and the same operation as described above is performed with the start address shifted by one line. by this.

The first P12 and second P2 connected at one joint point shift upward on the monitor screen. It will be done.

As the screen shift progresses, the output of the M2 counter (5) reaches the lower end joint point L2, so the memo II-Ml
The counter (c) for M! starts counting from its preset value Us based on the output of the comparator (to). An address is given to I, and the memory output is transferred from M2 to Mi.
It can be switched. In this state, the memory output changes twice from M1 to M2 to M5 on the seven-unit screen.

Thereafter, when the count of the counter (c) increases and the first image P1 completely disappears from the monitor screen, the comparator all detects this based on the bottom seam data L1 of the first image P1, and uses the output for M2. address shift counter (
2) starts working. The starting address of the output of the counter (goods) is preset in the counter (5),
A counter (5) operates based on this start address. The monitor screen is the 2nd mfl! Pt → 3rd painter P
s or the second P2 → third Ps → fourth P4 (not shown). The operation is the same as described above. Note that the output of the comparator Cυ is sent to changeover switch 01 in order to select the group of memos tJ-M2 and Ms%M4.

As described above, the images in each memory are spliced together at one splicing point to form a continuation of the screen that moves upward by the same number. The moving speed of the screen can be arbitrarily selected by the step rate of the start address. In addition, using the same method, the horizontal direction of the screen and the memory M1. M2...
If a memory chip selection signal for selecting each chip of . Furthermore, instead of a moving screen, a still screen spanning overlapping still image information can be formed in the same way.

According to the present invention, a series of objects to be imaged are imaged, as well as a sign indicating the joint position point, and a stationary i! 1111I! This is intended to form continuous video information that spans the overlapping still images by splicing the information together (by splicing C). As a result, based on the information of the overlapping still images captured and recorded, Information on duplicate still images, moving screens such as numbered tickers,
Alternatively, the formation of still screen video information can be automated with improved operability while requiring a smaller memory capacity.

Moreover, since the information of overlapping still images can be extremely easily joined together using the markers indicating the joint positions, the operability is extremely good and further automation can be achieved.
