content: Hi guys. I am translating a French patent into English and am unsure what the English translation is of the French term "matrice de pixellisation".The patent relates to a head-up display that is used for displaying information in a car. It says that "such devices use an image generator and a semi-reflective optical element configured to form a virtual image of the image from the generator. The virtual image is superimposed on the environment in the field of vision of the driver. It is also possible to use the windshield of the vehicle as a semi-reflective optical element in order to form the virtual image."It then goes on to say "Image generators used in cars comprise one or more light sources and a "matrice de pixellisation" which receives the light beam from the sources. The matrix transmits or reflects the light beam by printing an image which is formed using the pixels." Would "rasterizing matrix" work in this case, or possibly "pixelating matrix", or another term?Thanks

content: I would say "pixel matrix", and suspect that's the term that it got translated into French from to begin with...

content: I think it would probably translate to "dot matrix" display. IE a graphical LCD panel most likely.

content: Quote from: amadill01 on May 12, 2017, 02:38:31 pmThat doesn't make sense. "one or more light sources" probably should be "one or more information source". I suppose you could combine actual light sources, if eg. there was an analog projector mixed with digital overlay, but that would be an odd way to do it, since everything can be handled digitally. Even if it were combining actual light source, it wouldn't got through any sort of matrix, what would be the point of that?It's impossible to be sure without the context, but it may/probably should read :Image generators used in cars comprise one or more information sources and a pixel matrix display which generates the light beam from the sources. The matrix display transmits or reflects the light beam by displaying an image which is formed using the pixels.

content: Ah, I don't even have to stretch my limited French much - there is an almost identical document to the one I just linked picked up from google.ca - in this case the Canadians, being bilingual, have a translation. Not sure if it has been machine generated but the paragraph which mentions matrice de pixellisation is translated asThe image generators known in the automotive, include one or more light sources and pixelated matrix that receives the light beam sources. The matrix transmits or reflects the light beam by printing an image that is formed through pixels. Each pixel is individually controlled, and can either have a so-called "open" position, wherein the light incident part in the image, or a so-called "closed" position, wherein the incident light is not involved in the displayed image. Thus, depending on the open pixels, compose an image. a laser scanning can also be used as image forming means.French doc:http://www.google.ca/patents/WO2016087804A1?cl=frEnglish doc:http://www.google.ca/patents/WO2016087804A1?cl=enIt sounds machine generated although I can't come up with anything much better than "The image generators known in the car" for the first sentence which doesn't really mean anything. Connaître (the past participle of which is connus) doesn't really have another sense than "know" so perhaps there is some French patent language thing going on.However if you read the whole thing (or at least a few more paragraphs of it), then it becomes clear that they are talking about some sort of semi reflective dot matrix display where each pixel can either be transparent (presumably so that you can see the road) or illuminated.I can only find the phrase "matrice de pixellisation" in a couple of patent documents, it is probably not a widely used term (certainly I'd not heard it previously but that doesn't mean much).

content: How about DLP mirror array, if it is a pixel switch, or it could be a transmissive LCD display used as a display device, like in any cheap projector.

content: I think "raster matrix" (as used in point 11. of the english version of the patent) does the job quite well.

content: Hi grumpydoc. The English patent translation you found is indeed a machine translation based on a statistical translation approach where google translate linearly matches up words in different languages based on translated content already available on the net. It isn't at the stage of taking into account context yet and expertise within the field. What is the difference between a dot matrix and a raster matrix? Would a dot/raster/pixel matrix all be very similar? Thanks all

content: Further to my last post, the patent I am translating says the "matrice de pixellisation" is a thin film transistor matrix/array. These tend to be used in LCDs, yes?

content: Quote from: amadill01 on May 15, 2017, 09:41:01 amIt would actually be a little frightening if google had got its AI to the point of "comprehending" the document. That said I was reasonably impressed with the quality of the translated text - they are definitely improving (though Google translate still comes out with complete rubbish rather too often)QuoteDot matrix is a rectangular grid of individual pixels, a raster is produced by some sort scanning mechanism.Quote from: amadill01 on May 15, 2017, 09:56:14 amI would just use pixel matrix - there is discussion of possible technologies later in the document - thin film is mentioned but also laser (hence talking about raster displays I guess).
