Abstract

PURPOSE:To design a film format of a high degree of freedom from outside by converting the defined format specifications into a simplified command list to register it into a command library and calling successively the command list out of the command library to interpret and edit it. CONSTITUTION:The latent film format specifications are converted into a simplified command list in the form of an editing processing procedure and then registered into an on-line library via a means 1b. As a result, the film format editing jobs so far carried out individually can be performed integrately by calling out properly the registered command list to reproduce it with a base editing processing means in an executing state and performing the editing control to a picture editing device 5 in response to the editing conditions. In addition, the format is added and changed easily as necessary just by correcting the command list in an on-line system. Thus a film is designed at a high degree of freedom in an on-line system.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a satellite image output control device that latently images satellite images on a film, and can be used in a wide variety of ways, particularly in response to the purpose of use of the film and user needs. The present invention relates to a satellite image output control device suitable for online film format design.

[Conventional technology]

Conventional satellite image output devices differ in the recording content of satellite image data (e.g., image size, number of bands, attached data, etc.) depending on the purpose of receiving the launched satellite, and also have different output specifications (e.g., in accordance with user needs). , image enlargement/
Display of reduced 2 characters and symbols, display position of latent image items, etc.).

Fix the output of diversifying film formats.
The format was edited using an understanding method. However, although editing processing modules for common output items (for example, editing of characters and symbols, editing of annotation information that is data attached to two images, etc.) in various film formats have been standardized, Line editing and output control, which control the layout, were developed on a case-by-case basis. In addition, the film format itself is a fixed format, and once designed and
Created format (actually editing/output program)
Changes occurred in the program and were not easily possible. Additionally, related devices of this type include:
For example, there is a description of ``Exploring the Earth from Space'' (written by Iwao Nakajima).

[Problems to be Solved by the Invention] The above-mentioned conventional technology requires the development and modification of editing processing means with film format in mind in order to accommodate new satellites and various types of sensors. There were problems in terms of expandability such as addition and maintenance.

An object of the present invention is to be able to design a variety of film formats online due to differences in satellite images individually recorded by various sensors and differences in output specifications depending on user needs.

[Means for solving problems]

The above purpose is to provide a means for externally defining physical film format specifications for each sensor for each output item or for each ordered plural output items, and a command format that simplifies the defined formats 1 to 1. The editing process includes a film design conversion device that converts the command list into a command list, registers it in a command library, and deletes it as necessary; and a latent image converter that sequentially calls the command list from the command library, interprets it, and issues editing control instructions. This is achieved by having a control device.

[Effect]

The satellite image output control device converts latent image film format specifications into a simplified command list as an editing process procedure, and registers it in an online library, making it possible to perform film format editing that was previously done on a side-by-side basis. , call the registered command list in a timely manner,
This is possible by reproducing the data in an editing processing means on a runtime basis and controlling the image editing device to edit according to the editing conditions.

Additionally, formats can be easily added or changed as needed by simply modifying the command list online, allowing for a high degree of freedom in film design online.

〔Example〕

The present invention will be explained in detail below.

FIG. 1 shows the configuration of a satellite image output device.

As a component, a film design conversion device 1.3 stores physical film format specifications to be outputted in advance into a command library 9 as an editing process procedure. Image input device for inputting CCT which is fingernail image data 2.
3. A buffer switching device that performs alternating buffer control and sequentially reads out the input image data in order to buffer it in the input buffer 8. 4. A WpI image control device that decodes the registered editing processing procedure and performs editing control;4. An image editing device 52 that edits the input image data and edits character patterns, symbols, etc.; an output control device 6 that controls DM, A transfer to the output device 7 in order to convert the edited data into a film latent image; It consists of

Next, the operation of the film design conversion apparatus 1 will be explained.

The man-machine input table [1a is the physical film format specification of the film corresponding to each user. Partition definition (definition for dividing one film into multiple parts according to the purpose of film output, satellite image size, etc. and outputting #2 collection) and each output item corresponding to the specifications for film format 1 in the partition Provides input support for the definition of each item, such as the AN attribute, output position, characters used and character size, display symbol specifications, etc.

In addition, in order to eliminate mistakes in film definition in advance, the input film format specifications are subjected to predetermined rationality checks and logic checks (for example, overlapping output items, protruding items, etc.) to ensure efficient film production. Provide a means of definition.

The conversion device 1b performs conversion into a simplified command list for editing based on the input specifications.However, if the editing processing for each output item in each partition is simply converted into a command list, it will be enormous. In order to reduce the amount of information and processing time, one editing process will be made common and the command list will be compressed. At the same time, all relative addresses are added to each output item, and map information (the length and width of the film are called lines and pixels, and coordinate management information in the line direction) manages the physical relative output position on the film. is converted into line map information and coordinate management information in the pixel direction is converted into pixel map information) and registered in the online command library 9 along with one editing procedure. Further, it was registered in the command library 9 as necessary. It has a library mechanism 10 that constantly updates related information online in response to additions/deletions to the command list and changes to information in the command list. Based on the command library 9 thus registered, the operation of the satellite image output device that performs film latent imaging will be explained.

The image input device 2 sequentially reads image data taken by one artificial satellite into a controlled input buffer 8 by a buffer switching device 3 that performs alternating buffer control based on the CCT recorded according to a predetermined format. put out. In addition, the scene information of the film latent image (shooting date, satellite orbit information, annotation information, etc.) is read out as image auxiliary information as necessary, separately from the input buffer.
On the other hand, the latent image control device 4 calls a predetermined command list and map information from the registered command library 9 to the analysis buffer of the core 2. The latent image method for film is a method in which editing and output for each line (n pixels x 1 line) is repeated for all lines (due to limitations on the output device), and one editing control is based on the latent image method described above. , the line MAP information called into the second core is compared with the first editing line counter to determine whether or not editing is to be performed. When the need for editing is detected, pixel map information corresponding to the line MAP information is automatically searched for and a start command is issued to the editing processing device 5 according to the editing classification of the command list. As a result, the editing processing device 5 sequentially analyzes the command list belonging to all the searched pixel MAP information, reproduces the line editing specifications for each output item corresponding to the corresponding line, and Character pattern generation circuit (outputs character information such as scene information and film latent image information) 1 Graphic generation circuit (outputs symbols, marks, etc.) and image editing circuit (FCC
Editing of the image data read from T is controlled to output black-and-white and color images.

:This will fill 1 line of edited data.
1. Control high-speed DMA data transfer to create a latent image.
A startup command is issued to the output control device 6.

As described above, by repeating line-by-line editing and output for a predetermined number of lines, a latent image is formed on the film corresponding to the intended film format.

According to this embodiment, the film latent images of various satellites and sensors can be obtained only in the M8 format by using the analysis method for the film format L.
