Meaning of 图像 in this sentence: 图片可作为单独的图像
图片可作为单独的图像

I suppose you need to know something about digital photography to understand that sentence.

图片 = video frame

可作为单独的 = could be made into or saved as a single

图像 = image or photo.

So, the technical English equivalent would be "the video frame(s) could be made into or saved as a single photo image"

Here is an example instruction on how it's done:-

"To extract and save a single video frame as an image:

Do one of the following:

    While the video is playing, click the Pause button at the frame you want to save.
    On the progress slider, move the pointer to display the frame you want to save"


Now try and translate the above instructions into Chinese, whether modern or ancient?
