The 2. The IMX reaches a frame rate of 60fps at 12 bits. With its high sensitivity and very good low light performance, this reasonably priced sensor is a great fit for security and surveillance applications as well as for factory automation and industrial solutions.
The sensor delivers high image quality in the visible light and near-infrared light spectrums. High sensitivity, low dark current noise, and no smear are unique characteristics of this sensor that provide excellent image reproduction and when combined with improved RGB color mosaic filters, excellent color reproduction with little to no additional processing. These chips feature an electronic rolling shutter with variable charge-integration time that allows more flexibility in capturing precisely illuminated snapshots.
In addition, this sensor provides a very low price to performance ratio making it ideal for many cost-sensitive applications. An anti-reflective coating version is available to enhance light transmission through the sensor cover glass, achieving even higher performance with a sensitivity of mV and SNR1s of 0. Industry and product experts at FRAMOS are available to support customers with the integration of these new sensors in their applications and projects. Expo Highlights News. News Categories.
Related Expos.There is a need for surveillance cameras to film with clear images in a variety of environments. Sony's image sensors meet this need by providing high-sensitivity performance suitable for night filming. Before provision of the logo data, a logo usage agreement will be concluded with the customer. Please contact a sales office in your area for details. Unlike the front-illuminated-type image sensor, the image is acquired through the back side where there are no obstacles such as wiring or circuits, so a wider range of light is collected on the photodiode, achieving high sensitivity.
Moreover, it uses the very first pixel specifically developed for surveillance use in a back-illuminated structure. Sony is introducing SNR1s [lx] as an index used to quantitatively evaluate picture quality at low illumination. A smaller value indicates better picture quality at low illumination.
Figure 1 shows a schematic of SNR1s measurement. A camera is placed so that the distance from the gray chart to the imaging surface of the image sensor is 1 m, the sensitivity [e-] and dark noise [e-] are measured, and SNR1s [lx] is calculated using the relational equation 1. The luminance when equation 1 equals 1 is SNR1s [lx]. For further details, contact your local Sony's sales company. Darkness arouses unease.
To capture images even in dark areas and ensure peace of mind, efficient capture of near-infrared light is essential. Sony's photodetectors are made with the optimum structure to capture near-infrared light and provide clear images even in darkness. With many surveillance camera images in which light and dark regions coexist, there is a need to clearly capture both regions.
To meet this need, this technology enables both the light and dark regions to be captured clearly to achieve higher surveillance camera visual recognition performance. What's SNR1s?
Network Camera/Dashcam CMOS - IMX291 VS IMX323 VS AR0238 VS OV4689 VS AR0330
SNR1s [lx] : A smaller value indicates better picture quality at low illumination. The applicable types are showed as [Surveillance] application in products page in this website.
Sony reserves the right to change SNR1s values without prior notice. Sony cannot assume responsibility for any phenomena occurring as a result of using released SNR1s values.Using their super high conversion gain technology, Sony has doubled the sensitivity compared to the IMX Precise analysis and efficiency requires image processing applications to deliver high-quality color images even in dark conditions.
By using a new-generation 3. Thanks to this, a higher voltage and therefore higher sensitivity is achieved even at for low amount of charge in the pixel due to a low number of incident photons. This high performance, ideal for vision systems in the industrial sector, is also supported by the combination of an extended high dynamic range HDR and increased sensitivity in the infrared range.
Digital overlap HDR DOL-HDR delivers the data from three exposures on a line-by-line basis rather than frame by frame, resulting in improved picture quality, especially under poor light conditions, compared to multi-exposure HDR. The IMX image sensor offers a versatile interface. Mass production will begin in July The industry and product experts at FRAMOS have specialist knowledge ranging from sensor to system, and provide customer support for the integration of new sensors into applications.

The chinese guys learned that just the Sony name can sell their camera. Will be this a good idea for them? Will the manufacturers start using this chipset if is cheaper than a 5MP Sony IMX, even they know that the Aptina name can not sell so good as the Sony name? I will offer here few YouTube links and in the video descriptions are included the download links for original videos which are all in this folder. In these two videos you clearly see that the AR managed the best the white balance situation at least for the dusk time situation:.
Last edited: Jan 10, Mtz said:. OK, if not working the folder link or downloading from the folder, individual links are on YouTube description. I don't want to offer in this thread links one by one because the first post will become too complicated.
I have been eying the new Aptina sensor, look like it will find use in some dashcams it seem to have what is needed for the job. I think i commented or mentioned it here not long ago. Mtz What version of firmware on the S? AS is on latest firmware. That blue tint is in only special situation of dust time. I updated the first post with two new comparisons during day and there you will see the same AS with same firmware without the blue tint.It's a great option to use this camera module!
Btw, imx sensor is more sensitive and price is only 10usd higher. Yes, MIPI module looks attractive and could be a better solution than current one we use. There are some open questions - first of all we should check out if it will work with RMS, but there are two very important ones beside that: is there gain adjustment available, and real camera sensitivity.
While we are now aware vendors specify USB3 IMX camera module does NOT support gain adjustment, and I do not see it specified on the link you provided below, I'm somehow afraid this will be the case with this module as well. Regarding IMX camera sensitivity, it should be compared with IMX using the same lens at the same time looking the same part of the sky. Does anyone have different information on this? Thanks, Peter E. USB3 IMX modules do not have gain adjustment option allowed, but fixed gain set to some very low value instead.Dahua HFW1831E (IMX334) vs Dahua HDW4231EM-AS (IMX290)
We tried all available options, please please let me know if I'm wrong!!! I'd be very happy if info coming in from Andrei turns out to be true, meaning we would have a more sensitive camera with gain adjustment at disposal so we may adjust it to the value we find out optimal as it turned out that 60 is somehow best choice for IMX network camera. The limited checking I have done suggests that USB image adjustments may be quite limited.

Damir, camera parameters are set by i2c interface and there are AGC and denoise control. Now THIS looks very promising, the line. Found two comparison tables attached where from I see some different values regarding sensitivity, we should compare cameras side by side to be sure. Security camera manufacturers and vendors use different techniques to measure the sensitivity which in the end do not represent what we need in the best way.
Pete: Yes, there are USB3 versions supporting gain control but their cost does not seem to be acceptable at the moment. The sensitivity is only a value for programmer from Camera-board. The ADC is on board sony-sensor. Testing is under real conditions at meteors, I test at 5 and 20fps, up to 10 and 15sec. By interessing i can search the pictures. I think you can not see this on different conditions.
You must have pictures at same meteor. Most important thing would be to have gain under control, meaning it shall not be chosen automatically by any internal camera procedure or set to some low value. As said, option stated in MIPI module pdf looks like it should allow us to set the gain to some value we find suitable for our purposes.
I have a friend searching for an USB camera which would be used as an autoguider for his deep sky imaging I can confirm that has a noticeably greater sensitivity. The advantage is not huge, but noticeable. The package should arrive in a few weeks. At the moment, there is information that the module has gain controls, but can not give out a picture in P resolution, only P 25 Also, I may need the help of those people who have good Linux skills.
I requested information, but no one answered me.Sales' Skype Technician's Skype.
Many people are looking for good high performance dashcams for their cars, or network cameras for video monitoring. Then, we compare low light performance under starlight condition. Under no moon light and complete dark outside, the camera still can see tree, tree shadow, sky. Both image sensors are released on the time when Sony unveiled Starvis technology. We can compare the dim light performance based on actual test report released by Sony.

In this round, we see that the IMX has a lower value of 8.
In essence, we can start to form an image in lower light with the IMX In this round, we see that the IMX has a better efficiency of This means more signal is provided for that given wavelength, creating a brighter image.
New Sony sensors : IMX 294 and IMX 390
The larger the well, the better is can drown out noise and not saturate quickly. The IMX excell ed in this round. In cases where you would like to see the brights and the darks in a scene, higher dynamic range is desired. In the 2MP range of these sensors, it really depends on your application! If you need low light sensativity, the Sony Starvis family of sensors excel due to the pixel architecture.

These new sensors are being released at an astonishing rate, which is great for the imaging market, but making it harder to make decisions in identifying the best sensor for an application.
We have put two more sensors into the boxing ring to battle it out and see how they fair in various categorizes. As seen in the diagram below, the metal wiring has been set behind the photo diode and decreasing the distance light has to travel. This new pixel design lends itself to improved sensitivity.
