Digital Overlap High Dynamic Range (DOL-HDR) mode with raw data output. High signal to noise ratio (SNR). Full resolution @60 frame/s (Normal), 4K2K @60 frame/s (Normal), 1080p @240 frame/s

When the digital-overlap (DOL) HDR feature is on, the image sensor captures two images in succession:one with a short exposure according to the bright region and the other with a long exposure adjusted to the dark region.

The IMX290LLR also supports the DOL (Digital Overlap)-type HDR (High Dynamic Range) function, and can realize multiple exposures with little exposure time difference.

Dec 27, 2016 · This new CMOS image sensor features SME-HDR (Spatially Multiplexed Exposure HDR) and DOL-HDR (Digital Overlap HDR), supports dual sensor synchronization operation, IMX477 also adopts the back-illuminated technology can achieve better image quality under low light illumination condition.

Sep 12, 2023 · I have an imx678 and I would like to use the DOL-HDR. Two months ago I posted an issue because the images of the long exposure frame and the short exposure frame were shifted during the combining process.

May 7, 2021 · Does IMX477 DOL HDR enable us to get image data with different exposures, or create HDR image itself and give just HDR image? If it enables us to get, how can I get these images with knowing their exposure metadata?

Jul 13, 2023 · I have an imx678 and I would like to use the DOL-HDR. I modified the .dts file but it appears that my short exposure image and my long exposure image are vertically shifted when they are merged together by the Nvidia ISP.

DOL： 是digital overlap的缩写，是sony的一种sensor多帧HDR技术。 索尼支持‘准同时’输出多帧不同曝光时间的图像。 ISP收到多帧图像后可以做图像融合，生成HDR图像。 IMX290 使用了这一技术。 multiplexed exposure的缩写。 这种sensor每隔两行的曝光时间分别设为短曝光和长曝光。 然后融合长短曝光的两帧图像，成为行数减半的一帧HDR图像。 空间分辨率损失了一半，就好像是做了1x2binning，所以叫做binned multiplexed exposure。 IMX135 and IMX258 使用了这一 …

DOL-HDR function The IMX385LQR supports a DOL (digital overlap) -type HDR function. This function uses a method that outputs the data for three frames with different storage times line by line instead of frame by frame, enabling improvement of picture quality especially under low illuminance when compared to the existing multiple exposure HDR ...

Nov 20, 2016 · IMX274 + Hi3519 solution based IP camera can deliver up to 4K UHD resolution (3840x2160) video with 30fps frame rate, IMX274’s DOL-HDR enables the camera to capture clear image even under difficult lighting condition. Moreover, the Hisilicon Hi3519 can support both H.264 and H.265 video compression standard.
