Color Story: The Process of Color Recognition

Color Story: The Process of Color Recognition

Standardized as an international standard (CIE/ISO)! People perceive the color of objects through their eyes.

I will introduce the process of color recognition. Color is determined by the characteristics of light emitted from a light source and the characteristics of objects that reflect or transmit that light. If we understand the relationship between the light that enters the eye and color perception, it becomes possible to express color quantitatively. This is the principle of color measurement. The measurement methods for the characteristics of various lighting sources, the characteristics of objects that reflect or transmit light, and the sensitivity characteristics of the eye to light as color perception (known as color matching functions) are all standardized as international standards (CIE/ISO). [Process of Color Recognition] ■ The differences in the spectral composition that enters the eye result in variations in visual perception. ■ The cause of this visual perception is due to the characteristics of the light that enters the eye, which is a property of light. ■ This light is determined by the reflection (or transmission) characteristics of the illuminated object, which is a property of the object. *For more details, please refer to the PDF document or feel free to contact us.

Color Story: Examples of Color Tolerance

Color Story: Examples of Color Tolerance

The tolerance range of colors can be expressed in terms of color difference values.

When the measured tristimulus values XYZ are converted to UCS (Uniform Color Space), they can be displayed in L*a*b* coordinates, allowing for the comparison of the magnitude of perceived color differences based on the distance between the coordinates of two colors. In other words, the acceptable range of colors can be expressed in terms of color difference values. We will introduce examples commonly used in JIS standards and various industrial sectors. 【Examples of Color Tolerances (Excerpt)】 ■ Non-evaluable area - The range of perceived color differences falls within the margin of error, even with specially calibrated color measurement instruments, making it indistinguishable by humans. ■ Identification boundary - The range of perceived color differences is within the reproducibility range of sufficiently calibrated color measurement instruments, where trained individuals can reliably identify the limits. *For more details, please refer to the PDF document or feel free to contact us.*

Color Story: Color Bias Determination Method

Color Story: Color Bias Determination Method

You can control the color while viewing the color deviation determination diagram.

The color deviation determination method is a convenient color management technique used when you want to quantitatively assess the deviation of the sample color from the reference value, the color difference between the previous lot and the current lot, and the direction and positional relationship of the sample color deviation relative to the target color. This method is similar to the display of an aircraft's automatic landing guidance system. 【Steps for the Color Deviation Determination Method】 1. Set the measuring instrument to the color deviation determination display. 2. Measure the target color. 3. Measure the sample color. 4. Determine the direction and amount of color deviation. 5. Summarize the results of the color deviation determination. *For more details, please refer to the PDF document or feel free to contact us.

Optical portable dissolved oxygen meter

Optical portable dissolved oxygen meter

It is a new type of dissolved oxygen meter that does not require flow velocity during measurement, does not need calibration, and has a long sensor lifespan.

This is a new optical dissolved oxygen meter that eliminates the issues associated with membrane-type DO (dissolved oxygen) electrodes, such as the need for flow rate during measurement, membrane replacement, and electrolyte replenishment. It is portable and can be taken anywhere, with measurement values displayed on a color screen, making it very easy to read and operate compared to other equivalent devices. It features a completely waterproof structure, a unique sensor shape that is less affected by bubbles, and a data memory capacity of 5,000 entries. Wireless measurement is also possible, making it even more convenient to use.
