Cloud Server Image Preview Processing for Multi-Device Sharing

The patent segments the image processing workflow into two distinct stages: preview generation using low-resolution images for quick display and sharing, and final output generation using high-resolution images only when explicitly requested. This segmentation allows the system to maintain image quality where needed while conserving network bandwidth during routine operations.

The patent applies partial action by transmitting only a portion of the full image data (low-resolution preview) for most operations, and reserves transmission of the complete high-resolution data for specific cases where users explicitly request full-quality images. This approach satisfies most bandwidth constraints while preserving quality access when necessary.

The patent implements preliminary action by pre-generating multiple versions of images with different processing effects (such as various filters, adjustments, and styles) and storing them in advance. When users access images, these pre-processed versions are immediately available without requiring real-time computation on user devices, thus providing diverse options while conserving computational resources.

The patent introduces a server as an intermediary that centralizes the complex image processing operations. Instead of distributing computational burdens across multiple user devices, the server performs all heavy processing tasks including applying various effects, adjusting parameters, and generating processed image versions, then delivers results to users. This intermediary approach enables versatile image processing while集中izing resource consumption on the server infrastructure.
