DISPLAYING IMAGES OF DIFFERENT DYNAMIC RANGES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18548179 titled 'DISPLAYING IMAGES OF DIFFERENT DYNAMIC RANGES

Simplified Explanation

The abstract describes methods and apparatus for graphics processing to produce a smooth transition between images of different dynamic ranges, such as Standard Dynamic Range (SDR) and High Dynamic Range (HDR) images. The method involves using a high frame rate during a transition period to allow properties of images to incrementally vary, including brightness, color gamut, and tone mapping. For example, a subset of HDR images is displayed at a higher frame rate than usual, while the brightness level of the display panel is adjusted incrementally from SDR to HDR levels during the transition period.

• Transition between images of different dynamic ranges
• Use of high frame rate during transition period
• Incremental adjustment of image properties such as brightness and color gamut
• Displaying subset of HDR images at higher frame rate
• Gradual adjustment of display panel brightness from SDR to HDR levels

Potential Applications

This technology could be applied in:

• High-quality video streaming services
• Gaming consoles and virtual reality systems
• Professional photography and video editing software

Problems Solved

This technology addresses the following issues:

• Smooth transition between images of different dynamic ranges
• Maintaining image quality and consistency during transitions
• Enhancing user experience with high-quality graphics

Benefits

The benefits of this technology include:

• Improved visual experience for users
• Seamless transitions between different types of images
• Enhanced image quality and color accuracy

Potential Commercial Applications

This technology could be commercially applied in:

• High-end TVs and monitors
• Digital signage and advertising displays
• Medical imaging and scientific visualization systems

Possible Prior Art

One possible prior art for this technology could be the use of dynamic tone mapping techniques in HDR displays to improve image quality and color accuracy.

How does this technology impact power consumption in devices using it?

The abstract does not mention the impact of this technology on power consumption in devices. It would be interesting to know if the high frame rates and incremental adjustments have any significant effect on energy usage.

Are there any limitations to the types of images that can be smoothly transitioned using this method?

The abstract does not specify if there are any limitations to the types of images that can be smoothly transitioned between different dynamic ranges. It would be important to understand if certain types of images or content may not work well with this method.

Original Abstract Submitted

Methods and apparatus for graphics processing, such as producing a smooth transition between images of different dynamic ranges (e.g., Standard Dynamic Range (SDR) images and High Dynamic Range (HDR) images). An example method generally includes using a high frame rate during a transition period to allow properties of images to incrementally vary. The properties may include brightness (i.e., luminance), color gamut, tone mapping, among others. For example, during the transition period, a subset of HDR images are displayed at a second frame rate (e.g., 120 Hz) higher than a frame rate based on the HDR images (e.g., 30 Hz). Simultaneously, a brightness level (as well as other aspects) of the display panel is adjusted incrementally from an SDR brightness level to an HDR brightness level during the transition time period over the subset of the HDR images.
