VSEngineering Contradiction Analysis

1Measurement precision

If high-resolution rendering is used to provide clearer image display, then image quality is improved, but power consumption increases excessively

Engineering Contradiction:
Improveimage qualityVSAvoidpower consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by differentiating rendering resolutions across different frame buffers. The primary scene (first frame buffer) uses high-resolution rendering to maintain image quality, while secondary scenes (other frame buffers) use low-resolution rendering to reduce power consumption. This selective approach allows the system to optimize power usage based on the actual importance and visibility of different rendering targets.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments the rendering workload by dividing frame buffers into primary and secondary categories. The rendering system processes the first frame buffer at high resolution while processing other frame buffers at low resolution. This segmentation enables the system to focus computational resources on the most important rendering tasks while reducing overhead for less critical ones.

Inventive Principle:

AI summary

Embodiments of this application disclose an image processing method and an electronic device, which relates to the field of image processing. A large quantity of rendering operations in a primary scene may be executed at a relatively small resolution, thereby achieving an effect of reducing rendering power consumption. A specific solution is: determining a first primary scene in a process of executing rendering processing on a first image, where the first primary scene is a frame buffer that executes a largest quantity of rendering operations in the process of rendering the first image by the electronic device; configuring a temporary frame buffer, where resolution of the temporary frame buffer is less than resolution of the first primary scene; and executing a first rendering operation on the temporary frame buffer when rendering processing is performed on the first image, where the first rendering operation is a rendering operation executed on the first primary scene indicated by an application program.
