The marketing name is the camera's "signature look"; the filing name is tone mapping. Intel's granted patent US10943335B2, issued March 9, 2021, claims a hybrid method for tone mapping — compressing the enormous brightness range of a real scene into the limited range a screen can show, while keeping the result looking natural and consistent across scenes. Its CPC cluster in G06T 5/00x is the image-enhancement art.
On the record, tone mapping is where a photo's character is decided. A sensor captures far more dynamic range than a display can show; something has to decide how to crush the highlights and lift the shadows. Do it one way and you get the punchy, contrasty look of one brand; do it another and you get the flatter, more neutral look of another. The patent's "hybrid" approach combines global and local tone mapping to keep scenes consistent — the engineering behind a coherent house style.
Novel, or just renamed? Tone mapping is foundational image-processing art with a long literature. The claim's interest is the specific hybrid method and its consistency goal, not the concept. As ever, the principle is old; the particular implementation is what is claimed and defended.
The strategic frame is that the phone-camera differentiation buyers attribute to "the sensor" is mostly manufactured downstream, in tone mapping and fusion. Intel holding this IP is a reminder that the image-pipeline expertise is not exclusive to the phone brands — it lives across silicon and ISP vendors, who license and supply the differentiation that phone marketing presents as proprietary.
Scope, stated carefully: this is a granted patent to Intel covering a specific hybrid method, within the crowded tone-mapping landscape. It does not lock up tone mapping; it stakes one approach.
Follow the filing, not the gallery. When two phones with similar sensors produce visibly different photos, the difference is being made in tone-mapping steps like the one this 2021 grant describes — a software decision, dated and on the record.
