咨询图片动画及滚动触发的ghosting效果的专业技术术语

Hey there! Let’s break down those technical terms you’re curious about:

1. 图片动画的通用专业术语 #

The general catch-all technical term for animations built using static images is Image-Based Animation. This covers everything from frame-by-frame sprite animations (where a sequence of still images plays in succession to create motion) to transition effects between different images—basically any animation that uses image assets as its foundation.

2. 滚动触发的图片残影（Ghosting）动画的专业术语 #

For that specific scroll-triggered image ghosting effect you saw, the precise technical term is Scroll-Triggered Image Trail/Ghosting Animation. In web development circles, this falls under the broader category of Scroll-Driven Animations (any animation tied directly to page scroll behavior). The ghosting effect itself is typically achieved by layering semi-transparent copies of the target image or using canvas/CSS techniques to render motion trails, all activated as the user scrolls the page.
