TITLE OF THE PAPER : "PICTRAL a MATRA line of 
image processing terminals 
for large size imagery". 
Author : SELIGMANN

Country + + FRANCE 
Comission number : IT 
With the new generation of large, high resolution satellite 
images such as LANDSAT D and SPOT, a new range of image | 
processing systems is needed. 
The solution proposed by MATRA is the PICTRAL line of products 
which provides large virtual memory and high resolution 
display. 
Main PICTRAL features : 
  
User oriented dialogue 
PICTRAL makes the interactive dialogue easier. Step by step 
guidance enables non computer specialists to operate with a 
direct access to PICTRAL SOFT man functions and PICTRAL SOFT 
macro files management software. 
New functions 
With PICTRAL, the field of image processing is widened at the 
highest performance level : 
. - large roam 
- stereoscopy 
- more graphic capabilities : color graphics connected to the 
image and following it (zooming, translations, etc..) as 
well as independant graphics (texts, charts for instance). 
Powerful local processing capability 
PICTRAL is controlled by a high speed Motorola 68000 
microprocessor. Its memory may be extended by disk. This 
enables users to work on a stand-alone mode and to implement 
new functions using a high level language. 
PICTRAL SOFT pan 
Panning view of 9000 x 9000 images. In addition to the classic 
roam function using 4 refresh memories to view parts of a 
double size image (1024¢ for the 512 standard, 2048“ for 
the 1024 standard). PICTRAL SOFT pan does more with access to 
9000¢ images and to multispectral images as well. PICTRAL 
SOFT pan works with 81000 KB image memory stored on disks. 
PICTRAL NET 
Connected To an ETHERNET standard network, PICTRAL will 
exchange data with any equipment on the network at a very high 
rate, thanks to the image oriented transfer protocol. PICTRAL 
NET, a MATRA product (this communication software is being 
registered by Xerox). 
High resolution 
At first requested for military and medical applications, the 
1024 standard is chosen in new fields for its sharp 
interpretation capability and better comfort.
