Camera BMP bug and fix

---

I was testing the quality of the camera after the QTek 106 ROM upgrade and noticed using the BMP format at XL size gave edges in images really bad jaggies.

Scaling by 50% gave a good image and looking closely at the image I suspected an interlacing fault. Turns out the odd and even scanlines have been swapped. A stupid mistake and one that HTC can very easily fix.

In the meantime I've made and attached a Photoshop action that will fix these jaggy images. JPG images don't have this problem, only BMP ones.

Original image:


Fixed image:


(in this case both images were rotated 90 degrees from landscape to portrait after fixing)

I hope this fix will work for others, let me know if it does.

BTW: The upgrade makes the video recording of the camera work absolutely great, no more split images.

I'm not sure attachments are working, here's a download link: click

i need it,too .Thanks

Hm... :? do not understand how to upgrade with downloaded file from this post? :?:

The attached file is not an update for your phone, it's an action for photoshop. You copy it to your Photoshop directory in "\presets\photoshop actions\".

Then in Photoshop select the menu item Window->actions (or alt-F9) and in the actions list you should see the "fix MDA Compact BMP" item.

After loading a BMP image from the camera you can select that action item, then press the 'play' button at the bottom of the actions window to activate the action.

This will fix the BMP image for you, after which you can save it.

There's no fix for this bug on the phone itself, that's why I made this Photoshop action to fix BMP images until such a firmware update is released.

thnx for the fix!
but why would you want to save as bmp anyways? does it yield better quality or retain more details? i think most ppl just save as jpg; they're probably pictures not worth quality anyways if they decided to take it on this phone

Thank you very much for your comments It really works!

Hey, do you now why .BMP photo doubles .JPG weight? Which one to prefer for best pic quality?

BMP is an uncompressed format, JPG has lossy compression, which means you lose image quality. Some noise and unsharpness is added.

Try taking the same picture in JPG and BMP format and compare them, the BMP image has noticable better quality.

Also, if you plan on editing an image, BMP is better. Otherwise you use JPG, edit and save in JPG again and get twice the quality loss.

With the bad quality of the camera any improvement in sharpness and noise is welcome

Yeah!:idea:

I`ve made some pics with my cam in JPG and BMP and now I can see difference between this two formats
Speaking the truth, I never had an intention to use BMP before...

You right - BMP is much more better.

Good to hear that you like the results.

When I have enough space on my memory card and want the best image quality I always use the BMP format. Drawback is that it's a bit slower to process on the phone.
