The second generation of Pregius sensors include the 3.2 MP IMX265 and the 5.0 IMX264. Relative to the first generation of Pregius sensors that measured 1\/1.2\u201d with 5.86 \u03bcm pixel size, the second generation have a smaller \u2154\u201d sensor format with a 3.45 \u03bcm pixel size. More impressive, the smaller size allows for compatibility with more cost-effective lenses. As Sony actively improves their rolling shutter CMOS technology in their STARVIS line, the pinnacle of global shutter CMOS performance and value continues to be the Sony Pregius.<\/p>\n<p>[\/vc_column_text][vc_column_text css=&#8221;.vc_custom_1508640324618{margin-bottom: 50px !important;}&#8221;]As new technologies are introduced each year, Sony continues to push the limits of innovation by improving image quality, increasing frame rates, and adding functionality. Focused on the consumer, Sony keeps each new innovation accessible with reduced costs and intuitive features. Anchored in the ethos of Sony&#8217;s Pregius line, Lucid products push the limits of digital imaging while keeping accessibility paramount. To understand the benefits of machine vision cameras that use the Sony Pregius global shutter CMOS sensor, we must first understand the basic building blocks of Sony\u2019s digital imaging technology.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner equal_height=&#8221;yes&#8221; disable_element=&#8221;yes&#8221;][vc_column_inner css=&#8221;.vc_custom_1508640176617{padding-top: 50px !important;padding-right: 50px !important;padding-left: 50px !important;background-color: #eeeeee !important;}&#8221; offset=&#8221;vc_col-lg-offset-2 vc_col-lg-8 vc_col-md-6 vc_col-xs-12&#8243;][vc_custom_heading text=&#8221;Differences Between CCD and CMOS&#8221; font_container=&#8221;tag:h2|font_size:36px|text_align:center&#8221; use_theme_fonts=&#8221;yes&#8221; css=&#8221;.vc_custom_1508640207932{margin-top: 20px !important;margin-bottom: 3px !important;}&#8221;][\/vc_column_inner][\/vc_row_inner][vc_row_inner equal_height=&#8221;yes&#8221; disable_element=&#8221;yes&#8221;][vc_column_inner css=&#8221;.vc_custom_1508640147878{padding-right: 50px !important;padding-bottom: 50px !important;padding-left: 50px !important;background-color: #eeeeee !important;}&#8221; offset=&#8221;vc_col-lg-offset-2 vc_col-lg-4 vc_col-md-6 vc_col-xs-12&#8243;][vc_custom_heading text=&#8221;CCD Sensors&#8221; use_theme_fonts=&#8221;yes&#8221;][vc_column_text]<strong>CCD sensors (Charged Couple Device)<\/strong>\u00a0 start and stop exposure for all pixels at the same time.

Compared to CCDs, CMOS rolling shutter technology provides cost effective high quality imaging and very high frame rates. Unfortunately, if the target or camera is in motion, the images captured display distortion in the form of image wobble, skewing, or banding. This distortion is due to the rolling shutter sensor exposing and reading out pixels one row at a time.

In Pregius CMOS sensors, all the photodiodes begin exposure at the same time. When the photodiodes complete exposure, the electrons flow into the analog memory and free up the photodiodes for the next exposure. This process is what allows CMOS global shutter functionality. After the charge is transferred to the analog memory, the conversion procedure is the same as rolling shutter sensors. The result is a global shutter CMOS sensor that captures non-distorted images while still utilizing Sony&#8217;s dual CDS technology for reduced random and fixed pattern noise.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner offset=&#8221;vc_col-lg-offset-2 vc_col-lg-8 vc_col-md-12 vc_col-xs-12&#8243;][vc_single_image image=&#8221;185877&#8243; img_size=&#8221;1000&#215;388&#8243; alignment=&#8221;center&#8221;][vc_column_text]<img data-opt-id=2111721539  decoding=\"async\" class=\"size-full wp-image-3405 aligncenter\" src=\"https:\/\/mlxrlrwirvff.i.optimole.com\/cb:UhP2~57313\/w:auto\/h:auto\/q:75\/ig:avif\/https:\/\/thinklucid.com\/wp-content\/uploads\/2016\/09\/caption-new-cmos-gs-01.svg\" alt=\"Sony Pregius Global Shutter Pipeline\" width=\"1000\" \/>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner offset=&#8221;vc_col-lg-offset-2 vc_col-lg-8 vc_col-md-12 vc_col-xs-12&#8243;][vc_column_text]<\/p>\n<blockquote>\n<p style=\"text-align: center;\"><em><strong>Above: \u00a0Sony Pregius CMOS Global Shutter Pixel Pipeline.<\/strong><\/em><\/p>\n<\/blockquote>\n<p style=\"text-align: left;\">The electron charge is quickly transferred\u00a0from the photodiode to analog memory.

However, some electrons do not drain and end up remaining in floating diffusion. These electrons combine with the next exposure charge, adding noise to the signal. This noise creates an unwanted textured effect on the image called \u2018fixed pattern\u2019 noise. Fixed pattern noise is most noticeable in low light imaging but can be successfully reduced using CDS. \u00a0CDS reduces noise by measuring the leftover charge from the previous exposure and subtracting that from the following charge (which includes both the left-over noise and exposure charge).[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/2&#8243; css=&#8221;.vc_custom_1501530868106{margin-top: 15px !important;}&#8221; offset=&#8221;vc_col-lg-3&#8243;][vc_single_image image=&#8221;185874&#8243; img_size=&#8221;medium&#8221; alignment=&#8221;center&#8221;][vc_column_text css=&#8221;.vc_custom_1501271874620{margin-top: 10px !important;}&#8221;]<\/p>\n<blockquote>\n<p style=\"text-align: center; font-size: 12px;\"><em><strong>Above: Fixed Pattern Noise (FPN) at 30 dB Gain<\/strong><\/em><\/p>\n<\/blockquote>\n<p>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_empty_space height=&#8221;50px&#8221;][vc_row_inner][vc_column_inner offset=&#8221;vc_col-lg-offset-2 vc_col-lg-4&#8243;][vc_single_image image=&#8221;185880&#8243; img_size=&#8221;500&#215;188&#8243; alignment=&#8221;center&#8221;][vc_column_text]<\/p>\n<blockquote>\n<p style=\"text-align: center; font-size: 12px;\"><em><strong>Above: \u00a0Sony Analog CDS Before Column Parallel A\/D Conversion.<\/strong><\/em><\/p>\n<\/blockquote>\n<p style=\"text-align: center; font-size: 12px;\"><em><span style=\"font-size: 12px;\">The noise that is left over from the previous charge is measured and then subtracted from the next exposure charge that mixes with the leftover charge.<br \/>\n<\/span><\/em><\/p>\n<p>[\/vc_column_text][\/vc_column_inner][vc_column_inner offset=&#8221;vc_col-lg-4&#8243;][vc_single_image image=&#8221;185881&#8243; img_size=&#8221;500&#215;188&#8243; alignment=&#8221;center&#8221;][vc_column_text css=&#8221;.vc_custom_1508641588860{margin-top: 10px !important;}&#8221;]<\/p>\n<blockquote>\n<p style=\"text-align: center; font-size: 12px;\"><em><strong>Above: Sony Digital CDS After A\/D Conversion<\/strong><\/em><\/p>\n<\/blockquote>\n<p style=\"text-align: center; font-size: 12px;\"><em><span style=\"font-size: 12px;\">Similar to analog CDS the digital\u00a0signal is read twice, once at the reset level and then again at the signal level.

Their low light sensitivity along with high dynamic range allows users to image in dynamically challenging lighting environments. Applications such as autonomous vehicles, informational traffic systems (ITS), or other outdoor environments can benefit from Pregius&#8217; imaging quality. As the lighting changes or the camera enters complex scenes with dark shadows and bright highlights, Pregius sensors will capture more useful imaging data than conventional CMOS sensors, allowing your vision system to make better decisions. In classic machine vision inspection applications, higher sensitivity will allow you to shorten your exposure time and speed up inspection time as well as potentially saving costs on lighting.<\/p>\n<p>&nbsp;<\/p>\n<p>\n<table id=\"tablepress-1\" class=\"tablepress tablepress-id-1\">\n<thead>\n<tr class=\"row-1\">\n\t<th class=\"column-1\">2nd Generation Pregius Features<\/th><th class=\"column-2\">Benefits to Users<\/th>\n<\/tr>\n<\/thead>\n<tbody class=\"row-striping row-hover\">\n<tr class=\"row-2\">\n\t<td class=\"column-1\"><strong>Global shutter<\/strong><\/td><td class=\"column-2\">Removes image distortion caused by motion.
