    JT,Thank you for your kind words. Much appreciated. One more from the shores of Lake Bled.We take this boat called Pletna and go to Bled Island on the Lake Bled. The church on Bled Island which houses a wishing bell. The 99 steps to climb up to the top to visit the church. The boss […]

    The 1st HDR image is magic. Bravo. I cannot conceive of capturing that kind of image while on vacation. You are always on the job.Secondly, a genuinely happy face never disappoints. So glad you had such a good time.JTStatistics: Posted by jbtaylor — Wed Sep 18, 2019 2:57 am

    Yildiz,Thank you. I loved the town of Koper and fell in love with all those countries visited though regrettably only for a day.Here are some from the visit to Bled. The place was so magical with rain, clouds and the greenery, I was concerned the light and shadows may be beyond the DR of the […]

    .I love the first one looking over at the bridge, Sury. The rain enhanced some colours and the ripples on the river's surface make for an interesting texture. The street and the buildings in the 2nd photo indeed promise a playful peekaboo. Nice plaza.Thanks for sharing,YildizStatistics: Posted by aster — Tue Sep 17, 2019 11:41 […]

Sony CMOS sensor background revealed

There is a white paper by Sony Semiconductor on the imaging processing which I think is in the HX1, //www.sony.net/Products/SC-HP/cx_news/vol55/pdf/featuring55.pdf. I assume it is the IMX-032 CMOS sensor (//www.sony.net/Products/SC-HP/cx_news/vol55/np_imx032cqr.html) mated to a CXD4109AGG image processing chip. There seem to be some interesting techniques employed, multi-plane synthesis to combine several frames for low light and HDR capture.

With the IMX-032, it is interesting to note that the on-board programmable gain amplifier has a gain value of up to 18dB or a factor of 8, so if base ISO is 80, then maximum “analogue” ISO is 640. If we compare the IMX-032 versus Sony’s first column ADC CMOS chip (IMX-017), the IMX-32 has an 11.8% better photo-electron efficiency per unit area (2300e per 1.75 micron square pixel compared to 4500e per 2.5 micron square pixel). Might be a sign that Sony is improving the process and design used to make their CMOS chips.

The backside illuminated chip is called the IMX-061, //www.chipworks.com/uploadedFiles/Aliased_Pages/CMOS_ImageSensors_Spotlight/Chipworks%20-%20Sony%20IMX061%20EXR-0902-813.pdf
6MP and 1.75 micron pixels in ClearVID (45 degree) layout with a 1:6:1 RGB Bayer filter array, sacrificing colour resolution for spatial resolution.

The Nikon D90 chip is called the IMX-038 (not the IMX-021 as for the A700), so this suggests it has significant revisions compared to the IMX-021 (possibly linked to LiveView and HD Video?).

    CXD4109AGG seems very interesting sensor while more suitable for video. I would by (for reasonable price) a video camera with 6 Mpix (2000×3000) resolution and 30 (60)fps. It could provide a lot of space for cropping and digital stabilization in PC video editing soft. Of course 500GB CF 666x card then would be very useful.
    While with existing processors I don’t believe in image sticking concept. To make a panorama from three 12Mpix images in my computer (Dual Core, 2Gb RAM) takes ~30s or even more. The same for HDR images. I couldn’t imagine how it could be done in photo camera for less than second, but anyway it’s really interesting concept.
