CA-410 Color Analyzer

The CA-410 is an optical measuring device used for inspection and adjustment of white balance* and gamma* at factories producing TVs, smartphone displays, etc. Designed as the successor of the CA-310, which is reputed for its rapid, accurate measurement, the CA-410 similarly offers high-speed, high-accuracy measurement of higher-dynamic-range (HDR) displays, including OLED displays.

1. Accuracy-Guaranteed Luminance Measurement Range 25 Times Wider Than the Previous Model for Higher-Quality HDR Displays

Recently, demands for higher-quality images and video have been growing among smartphone users, due partly to dramatic increases in communication speed. In response, manufacturers are accelerating the development of higher-resolution displays with improved contrast ratio and color reproduction, such as HDR displays. As a result, manufacturers of such displays require a color analyzer with a wider measurement range, from extremely low to high luminance.

With its new sensor circuits, the CA-410 achieves an accuracy-guaranteed luminance range from 0.001 to 5,000 cd/m2, 25 times wider than the previous model. This increased measurement range will help manufacturers to control and improve the quality of high-resolution displays, enabling smartphones and TVs to show higher-quality images and videos.

2. Faster Measurement Speeds to Improve Productivity

The CA-410 can measure extremely low luminance levels of just 0.001 cd/m2 in one second, fast enough for integration into manufacturing processes. In addition, total measurement time is reduced by 30% compared to the previous model by improving sensor capabilities and CPU calculation speed*3. This allows the CA-410 to contribute to higher productivity at factories producing high-resolution displays, such as by reducing the gamma correction process time.

3. Easy Integration into Automated Processes for the Digital Manufacturing Age

In anticipation of the needs of the digital manufacturing age, the CA-410 is designed as a sensor that can be easily integrated into automated manufacturing processes. It allows measurements to be started and performed without manual tasks, and the probe can be connected directly to the computer to save space.

*Measured under Konica Minolta’s standard light source (6500K).

*1:White balance is the process of adjusting the light intensity ratio of light in the three primary colors - red, green and blue – for accurate reproduction of white.
*2:Gamma is a measure of tonal response. Gamma correction makes the brightness and color of the black and white halftone appear more natural and smooth to the eye.
*3:Based on gamma measurement simulation compared to CA-310 under Konica Minolta’s test conditions (for 64 measurements). It excludes display startup time and wait time.
