The Las Vegas Sphere, with its massive 16K LED display, demands an unprecedented level of image quality. This necessity has given rise to the Big Sky camera, a large-format cinema camera specifically engineered for Sphere’s immersive visual experiences. A recently published patent (US 12,219,231) provides a deep dive into the technology that powers this revolutionary camera system. This article will break down the patent in detail, analyze its significance for large sensor cinema technology, and explore its implications for the future of filmmaking.

Understanding the Patent: The Core Technology

The patent describes a next-generation ultra-high-resolution large sensor camera developed to meet the unique requirements of ultra-wide, high-resolution immersive displays such as the Las Vegas Sphere. The most notable features of this system include:

1. A Gigantic Image Sensor

The patent outlines a massive 316-megapixel CMOS sensor measuring approximately 9.92 cm × 8.31 cm, which is higher than a 65mm-sized sensor with extreme resolution capabilities. This allows the camera to capture imagery at up to 18K resolution. To put this into perspective, high-end cinema cameras such as the ARRI ALEXA 65 and RED V-RAPTOR XL 8K use large sensors, but their resolutions pale in comparison. Even the Sony VENICE 2 maxes out at 8.6K resolution, while the Big Sky camera nearly doubles that. Read more here: This is the Sensor of the Big Sky Camera

2. Extreme Dynamic Range and Frame Rate Capabilities

The camera is designed to deliver 14.5 stops of dynamic range, ensuring excellent shadow and highlight retention, which is crucial for large-screen projection. The system also supports frame rates of up to 120 FPS, allowing for smooth motion capture, slow-motion playback, and seamless integration with the Sphere’s high-refresh-rate display.

3. Staggering Data Output at 32 Gigabits Per Second

One of the most groundbreaking aspects of the patent is the camera’s ability to handle massive data rates. The system records at a whopping 32 Gbps, necessitating specialized data pipelines, storage solutions, and post-production workflows.

4. Custom Lens and Optics for Ultra-Wide Projection

The patent also describes an optical system designed specifically for ultra-wide, immersive projection formats. This includes:

• Custom spherical lenses that minimize distortion.
• High-resolution glass capable of resolving 18K images.
• Adaptive focus mechanisms to maintain clarity across the frame.

5. Advanced Cooling and Power Management

Given the high-resolution sensor and immense data throughput, the camera incorporates a liquid-cooled thermal management system to prevent overheating. Additionally, it employs a modular power supply to handle extreme processing loads efficiently.

6. Proprietary Image Processing Pipeline

The patent details an advanced image signal processor (ISP) that is custom-built for handling 18K imagery. This includes:

• Real-time debayering and HDR processing.
• AI-powered noise reduction and sharpening algorithms.
• Color science optimized for large-format projection.

7. High-Speed Storage and Data Transfer

With a data rate of 32 Gbps, conventional storage solutions would be insufficient. The patent describes a high-bandwidth SSD array integrated directly into the camera body, along with an optical fiber-based data transfer system for seamless offloading of footage to external storage.

8. Modular and Expandable Design

The patent also emphasizes modularity, allowing users to swap out:

• Different lens mounts (PL, EF, and proprietary wide-format mounts).
• Multiple recording formats, including RAW, ProRes, and proprietary ultra-high-bitrate codecs.
• Custom sensor readout modes for different aspect ratios and resolutions.

Merely using materials with substantially similar coefficients of thermal expansion for adjacent components in the image sensor package is often not enough to preserve the integrity of various components and to ensure optimal operation of the image sensor package. Issues of different thermal expansion rates between adjacent components are especially prevalent in large format camera systems because components are larger in size, and any potential thermal expansion of a component will more significantly impact those adjacent components. Therefore, additional mechanisms are needed to accommodate for different thermal expansion rates of adjacent components during operation.

Implications for Large-Sensor Cinema Technology

The technology described in this patent signifies a major leap for large sensor cinema cameras. Let’s examine how it pushes the boundaries of high-end filmmaking.
