BTW, how fast your phone is? My 6260 seems to run on 123MHz ARM 1040.

How did you measure it?

In this case it should recover from the hang, when I disable screenupdate. Unfortunately it will not do that Sad
Yup, well let's see if we find a way to overcome that... other than using the frame skip that is. I already changed the code so that now screen mode 3 works (i.e. clear memory) properly. Since that is the command the digitizing software sends to the hw the first time the menu is drawn it could fix the hanging problem. In the released version that command also requested an image from the camera but after it was received it was simply ignored and the HBI-V1's image buffer was left untouched.

Snout, AFAIK that archive is broken! (At least I have not been able to open it)

You can anyway get a "tool" from jr homepage or you can install some file manager to your phone or use some sis maker out there or something like that...

I have installed TaskSpy, that tells this information. Some other programs can also tell this...

After I asked you about this, I also find this page, that might be interesting:

Yet another page, that proves, that my phone is crap!

Well, I guess I don't need to run that test program then since the page you linked already has the info on my phone (I'm using a 6630 atm).

Your YJK conversion looks very nice!
Thanks... but have you checked that it is at least somewhat correct? I mean, in the emulator the image is of course displayed correctly because I'm the one generating the YJK data and also rendering the YJK image. I was just thinking that it might be a good idea to check if an image captured with the emulator looks approximately the same on a real MSX2+ =)

About YJK<=>RGB: wouldn't it be better to capture the video in RGB format, display it in (enhanced) RGB format (say 5:5:5 instead of the MSX 3:3:3 tones), and only convert it to YJK when necessary (i.e. when saving an image)?

I think quite a lot of (emulation)time won't be misused anymore then, as there's no effort anymore in converting input RGB to YJK, converting YJK back to RGB to display it, etc.

That is, I assume the camera inside smartphones render RGB images Wink.

jr, thanks for your data. If you learn more, please let us know. We might try an implementation as well...

I have now implemented the support for the block size and block start parameters in the HBI-V1 except for the 1/3, 2/3 and 3/4 sizes -- I was wondering if anyone knows what the actual pixel sizes and positions for the images are when using these modes. This is because 256/3 == 85 1/3, which means you will either have two 85 pixel wide and one 86 pixel wide image, or three 85 pixel wide images and one pixel column is left unused...? And the same problem applies to image height (212/3 == 70 2/3).

Also, since the internal software always clears the whole screen, I was wondering if using mode 3 (clear memory) with block size & start parameters actually clears only the specified area?

D-Tail, do you mean that when the HBI-V1 digitizing process is started, I would actually show a "normal" RGB camera preview on the screen until you press a key and only after that the emulated HBI-V1 would get the digitized image? It would certainly make it easier to "target" the image you want to digitize.
