1.
reversal, inversion, flipping
Turning something to its opposite state — flipping an image, reversing a direction, or inverting a position. Used for physical rotation as well as abstract reversals of situation or trend.
画像を反転する。
Flip the image.
左右反転で写真を保存した。
I saved the photo with a horizontal flip.
試合の流れが一気に反転した。
The momentum of the game reversed all at once.
COMMON COLLOCATIONS:
- 左右反転 (horizontal flip / mirror image)
- 上下反転 (vertical flip)
- 反転攻勢 (turning to the offensive)
- 白黒反転 (black-and-white inversion)
USAGE NOTES:
Very common in digital image editing, photography, and design contexts. Also used in sports and news to describe a dramatic turnaround in circumstances. The homophone 斑点 (spot, speckle) is a different word.
