Abstract

Systems and methods are provided for simulating strobe effects with digital image content. In one embodiment, an image manipulation application can receive image content. The image manipulation application can generate blurred image content by applying a blurring operation to a portion of the received image content along a blur trajectory. The image manipulation application can sample pixels from multiple positions in the received image content along the blur trajectory. The image manipulation application can generate a simulated strobe images based on the sampled pixels and at least some of the blurred image content.
