JVC 真4K 投影機......會係10月免費提供dynamic TONE MAPPING功能既Firmware.....記住...係免費..
Dynamic tone mapping 係一個咩功能呢??JVC 叫佢做Frame Adapt HDR....意思即係一幅幅畫面幫你計數調整光暗...唔怕好似一般HDR投影機咁.....一係太光...一係太暗....
This feature forward update adds JVC's new Frame Adapt HDR function, which dynamically analyzes HDR10 picture level frame by frame and automatically adjusts the brightness & color to optimize HDR performance for each frame.
Because content brightness varies, a fixed setting cannot deliver optimum image quality. JVC's new Frame Adapt HDR solves this by instantly analyzing the peak brightness of each frame or scene using a proprietary JVC algorithm, and adjusting dynamic range to provide the best possible HDR image. Frame Adapt HDR works with any HDR10 content, even content that does not contain brightness metadata (Max CLL/Max FALL).
Main Features
1. Delivers images closer to reality
Dynamic range is adjusted in real time for optimal image projection. At the same time, saturation, hue, and brightness is analyzed and optimal corrections are made, which reduces color loss.
As a result, even within a single program, darker scenes have deeper blacks with enhanced color. Bright scenes have higher peak brightness without color loss while maintaining black level. All content is reproduced closer to what the human eye is capable of seeing.
2. Compatible with all HDR10 content
Frame Adapt HDR adjustments are based on analysis of the input HDR10 signal. Therefore, it is effective on content with or without mastering information. As a result, all HDR10 content can be enjoyed with greater dynamic range and image quality than ever before.
3. Smooth gradation with 18-bit level gamma accuracy
The gamma processing accuracy, which in the past was based on 12-bit equivalent, has been improved to 18-bit and as a result gradation performance is dramatically improved. In any given scene, it reduces the banding effect in the bright portions and the crushing of dark portions. This provides accurate, smooth gradation along with higher average peak level brightness and increased color saturation, which has previously been a challenge with HDR content.
Other Improvements
Support for 16x9 content when using a Panamorph Paladin DCR lens (adds Anamorphic D). It is now possible to leave a Paladin DCR lens in position and view both ultra-wide and 16x9 content correctly.
Auto Calibration support for Spyder X sensor.
Adds new presets to screen adjustment function.
The firmware will be available for download at no charge in October for the DLA-NX9, DLA-NX7 and DLA-NX5 as well as the DLA-RS3000, DLA-RS2000 and DLA-RS1000.
