Sony has released specs for a new IMX Cellphone oriented sensor that has a whopping 48 Megapixel photosite grid with a new Bayer altered pattern of quad pixel colors that aims to quadruple the dynamic range of the signal and increase detail retention significantly by supersampling every photosite and creating a final 12MP image with excellent characteristics.
As far as frame rates go we were glad to see very high-end read-out speeds for this sensor as full 4k video can max out at 90fps and other high fps settings include 1080p 240fps full area downsampling and 720p 480fps but with a cropped windowed frame extraction. At 48MP or 12 regular De-Bayered then we expect the crop to be quite extreme at the 720p mode unless they do a 4 or 6MP downsample.
The Chronos 1.4 Team has now posted the first incarnation of the RAW Camera data to DNG File tool to convert the sensor information files to usable Adobe DNG sequences. They also have posted a sample image comparing the before and after characteristics of the image quality if saved on H.264 in camera and then the same scene shot and saved in RAW format which converted to DNG yields a substantial improvement in image quality as we explored in our previous post about this issue here.
The camera is expected to allow direct to DNG format file saving in the future but now you can shoot in the camera RAW format and later convert as an interim solution without sacrificing quality on the H.264 files. Maybe in the future, the camera will be able to simultaneously save RAW and H.264 files as a proxy feature to be able to easily sample clips in editing before conversion. We believe the DNG format should be your one-stop solution for this camera if image quality is important for your use case.
We received a set of Adobe DNG image samples from Krontech to check the resolution, dynamic range and grading potential of the camera when using the RAW recording mode. As of now the utility to convert the raw data is still being tested but we were impressed by the results the camera was able to achieve by offloading the de-bayering process to a more capable converter like the Adobe Camera RAW module.
The Chronos files were already good when properly exposed but did suffer from some aliasing and moire in fine detail while resolution also took a hit by saving in a compressed H.264 format. Now with the DNG RAW capability, we are glad to see that the camera image quality made an enormous improvement in the resolution, color fidelity, and dynamic range. It really brings out the real potential of the camera for a variety of applications, also creating a cleaner result in the noise department when processed correctly.
Sony is not only pushing the frame rate boundaries of CMOS sensors with their Stacked technology; but now it’s implementing and improving on the design with circuitry that can track objects with pinpoint electronic precision based on pixel colors, contrast, and motion vectors. The result the IMX382 is a complete tracking sensor solution that could one day be used for full AF during high-speed video capture by accurately representing the scene.
While 1000fps is not the end all be all of high-speed frame rate, the fact that it can accurately track with very little lag the object motion in front could one day translate into perfect autofocus capability for many types of cameras. Not only the focus department is improved by this technology but now you can use the sensor in all sorts of industrial, law enforcement, traffic cameras and monitoring solutions for robotics.
The Zuk Z2 has been released and as it’s customary from many manufacturers they omit the slow motion or just mention it as an afterthought. According to the press release it does support 960fps video recording but nothing else is mentioned. There is a mention of the feature still not active in the pre release phone due to software lag which will be released at a later date.
That however has not deterred us from crunching some numbers and getting a good estimate from the Samsung 13MP ISOCELL sensor used which gives us clues as to what to expect in terms of higher frame rate support. lets dig in!
