Abstract

PURPOSE:To reduce the capacity of a memory and to reproduce continuously a still picture signal as for plural still picture signals by allotting a two-field memory for reproducing of still picture and allotting a one-field memory for rewrite of still picture signal and switching this one-field memory successively for reproducing of still picture. CONSTITUTION:With respect to still picture signals read out from RAMs, the RAM 3 is selected by an MPX 6 when odd field data of a still picture 1 are completely written in a RAM 3, and field pictures of the still picture 1 are outputted repeatedly. The MPX 6 selects RAMs 3 and 4 alternately to output frame pictures consisting of even odd fields from a point D of time, when even field data of the still picture 1 are completely written in the RAM 4, to a point F of time. In this case, odd fields of the next still picture 2 are written in a RAM 5 in the period from a point E of time to the point F of time. When even field data of the next still picture 2 are written completely in the RAM 5 at the point F of time, the MPX 6 selects only the RAM 5, and still picture data are outputted repeatedly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The aim of the misfire t3A is to use a reproducing device that is extremely suitable for producing a still image W that is still in good condition.

[Evening night in Kyoto]

One frame of stillness! Record one part on the audio track of the video chief or a recording medium such as the audio chief, and at the time of Niu, 41) Pressed stillness 1fflN! Write the number to memory, read it repeatedly, freeze and play it again. In this technique, seven words are recorded in a recording medium, as shown in Japanese Unexamined Patent Application Publication No. 40570 and Japanese Patent Application Publication No. 5-611j73. At the same time as the name became digital, it was buried in the time axis and became the name of the Emperor.
Records of low-speed walking are recorded on the body. In addition, in the 8 main case from the spherical mass, the still 11118 generation device equipped with the above memory performs threshold pressure movement and analogization when the still image signal is 881:, and the Uchitani frame is fil) Form the return video flight number Ding Φ0 here, on! d
In the device, two 1-field RAMs (Random Access Memories) are used as the above-mentioned memory, each of which can store still image signals or 1 field. The fields are entered one by one, and when they are spread, the 6th and 9th speeds of writing are written to each other with a direct line that is larger than the light.Thus, the original time is 4I.
A still image signal of one frame returned to llrc is repeatedly obtained, and the still image signal is returned to llrc. Where Il Niu is performed, a plurality of still signals are recorded on the recording medium, and when these t-l are reproduced next to sequentially perform still-reproduction,
In the above-mentioned prior art, a certain stationary I! Iig! When the next stationary number is erased from the recording medium during still-playback of the first issue, the next stationary number is erased from the recording medium. In order to perform the 118th generation, this reproduced stationary signal must be loaded into a large amount of RAM, and during this loading time, the stationary signal stops sweating. This is a rather large period, which is vague compared to the period of stationary signal which is dominated by 4% from the m* body. Also, multiple stationary 11
If No. 11g No. 1 is recorded on a recording medium in a short period of time, the reproduction of the next still image No. M starts immediately after the reproduction of one still image signal ends. In fact, a stationary lltIi88: is impossible.

ρ) In order to resolve Karuma Satoshi, the same RAM
When the next still image signal is played back from the recording medium while one pair of RAMs is being adjusted, the still image signal is added to the other pair of RAMs. It is conceivable that once the common practice of writing to RAM is completed, reading can be performed and the 5 RAM pairs can be used.

But/Yogara, it takes #stop! According to EE movie,
Otani Ju's number of 1@value RAM has increased, and it is still! I
There is a 5-room meal that will be priced at the market price with the Niu fi direct.

Purpose of lt #14] The purpose of the failure case is to solve the good luck point before the above-mentioned Jumei throw rM L
, memory valley Jtt 150 g, then continuously multiple stationary 1! It is to provide the stillness #J Niu t' which has been made 5 so that it is possible to do 5 by performing the 5th motion.

[Summary of the invention]

In order to avoid this problem, we used 3 fields' worth of memory for the unexploded case, 2 fields' worth of memory for the still image, and the remaining 1 field's worth of memory for the still image g7Iv standard. By cutting out one field's worth of memory for still image playback, it is possible to create a still image for a long time! ! There is a characteristic of a fish that smoothly cuts the length during the period in which the number is sent to χζ now 5. .

Still image signals for one field are stored in RA1M4 during the CND period, and in RAM5 during the periods E to F.

FIG. 5 is a timing chart showing the creation of the rigid embodiment.

In the case of Husband 71fI, which was previously shown in Figure 1 of Seed (Eng., B in Figure 2).
The period from point D to point D becomes a field theater group, and from point E to F.
Point σ] period is frame l! It can be seen that there are 11 rules, and the difference in the painting circle is noticeable. Therefore, in this 5A# example shown in Fig. 5, by taking advantage of the large correlation in the direction of the shoreline of the -volume, we use a line based on the otti field cheetah as aug le tweald data during the period when field attenuation is output. The field mftR obtained from the correlation is made into an ebb to be output.

In this way, until still image 1 -〇# Lutweald Cheetah is loaded into RAM 5, the line average field data written in RAM 4 is used instead of this aug Lutweald data. used as. This lees rice is superior in static m and RAM 5.5 by alternating the threads of RAM 5.4.
There are 21i1. There is no V-work.

Next, using the timing chart of FIG. 6, another creation based on the actual image shown in FIG. 5 will be explained. This creation is a still image 1M 2 ocLcL field data is RA
Up to the FQ injected into M2, it is the same as the creation shown in Figure 115. By the way, still image 2 from product F to point if
When I played it back, this still image 2 was unpopular, so
There are times when I want to hold on to the next still image. At this time, the address control circuit 8 stops sending the corrected screen generated by the signal processing 1kS13 to the HA skin 1, and controls the still image 5 to be transferred to the RAM 2 again. The static lllIm is static image 1 from point B to point F, static m lotus 2 from point F to point F, static image 1 from point H to point 1, and static image 3.4 from point I onwards. As mentioned above, by having a field memory for 3 fields and creating a correction law using frame correlation, it is possible to cut a standard still image from above to when it appears. It is possible to display the image while

(Effects of saEA) As explained above, according to the BA system of this invention, it is possible to carry out uninterrupted command of the standard stationary M8 student in response to the following signals that are being used one after another. , it is possible to reduce the memory load required for the still image reproduction, and to solve the problem 4I of the conventional technology described above, it is possible to provide a still image reproduction repair with a broken function.
