動画-録画ソフト(処理速度を速める方法)

[kozuka32]

平素お世話になっております。

LabVIEW2017でキャプチャーソフトを作成しました。フレーム数に応じて写真も取り入れる様にしていますが、その処理に時間が掛かります。処理速度の改善方法をご教示願います。出来れば、添付Viを修正して頂けれるとありがたいです。よろしくお願い申し上げます。

I don't have Imaq installed. But have you tried to use onel one loop ? Did you use this arquitecture to avoid loosing frames ? 

I wonder if this is a memory consuming architecture. (This is just a guess).

Thank you for your continued support.

I have created a capture software in LabVIEW 2017. I am trying to include pictures according to the number of frames, but it takes a long time to process them. Please let me know how to improve the processing speed. If possible, I would appreciate it if you could modify the attached Vi. Thank you in advance.

I see several things that may slow down your application:

 - Continuously saving each individual frame to disk. Not sure how to do that more efficiently...

 - Continuously converting the image to array and then back from array to image. That may be more efficient to directly perform a copy of the source image instead.

Attached is a proposed improvement.
