Starting with Android 14, Google has addedAn image format called Ultra HDR, allowing the phone to present more realistic HDR images and significantly improve the contrast between bright and dark details. Currently, an API resource called Camera 14 has been added to Android 2, allowing third-party camera apps to shoot Ultra HDR images. Earlier, the Ultra HDR image format was brought to an API resource called Camera X, allowing third-party service apps such as Instagram that can take photos and upload them through mobile phone cameras to also shoot Ultra HDR images.
The Ultra HDR image format proposed by Google will allow images captured by mobile phone cameras to present more natural HDR images, rather than directly changing the image brightness curve like traditional methods, making the overall image look artificial, and can truly present the details of the bright and dark areas of the image.
This time, through API resources, more third-party camera apps and third-party service apps can use the Ultra HDR image format, which means that Google hopes to use this to promote a new image format and thereby promote the use of Android phones to shoot image content that is closer to real light and shadow performance.
Currently, Ultra HDR images are based on the JPEG image format, and additional HDR information is added to its metadata. This allows all display devices that read the corresponding JPEG format files to add HDR effects based on this metadata information. Even content originally presented in the standard SDR image format can be added with HDR effects to present more realistic light and shadow contrast effects.
