Problems solved by technology

[0005] However, if the colorimetric device is miniaturized, the size of the integrating sphere also becomes smaller, so a separate hole is opened for connection with the camera, which causes a significant deterioration in the mixing performance, which is not preferable

Embodiment Construction

[0041] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0042] figure 1 It is an external view of a portable colorimetric device 1 according to an embodiment of the present invention. This colorimetric device 1 has a measurement opening 2 at the lower end, a display panel 3 made of liquid crystal or the like at the upper front, and a measurement button 4 below the display panel 3 .

[0043] The measurement opening 2 is a portion for aligning the lower end opening with the sample 100 to be measured. The display panel 3 displays a measurement result of the measurement device 1 or an image of the sample 100 in the measurement opening 2 captured by a camera described later. The measurement button 4 is an operation button for the user to press when starting measurement.

[0044] An integrating sphere is provided inside the colorimetric device 1 . figure 2 It is a figure which schematically shows the structure of the integrating spher...

Abstract

The present invention is provided with: an integrating sphere (5) having a measurement opening (2) and a well hole (8); a well (11) disposed so as to be able to open and close the well hole; a non-reflective cover (30) disposed so as to be able to open and close the well hole; an imaging mechanism (9) disposed at a position at which the sample (100) facing the measurement opening can be imaged through the well hole; and a display means (3) for displaying the image captured by the image capturing means. When the reflected light from the sample is measured by the SCI method, the well is moved to a position where the well hole (8) is closed by the well (11), and when the reflected light from the sample is measured by the SCE method, the lid is moved to a position where the well hole (8) is closed by the lid (30).

Description

technical field [0001] This invention relates to a kind of colorimetric device, can use integrating sphere to measure the reflected light under the condition (SCI (Specular Component Included)) that contains the specular reflection light from the sample, and under the condition that removes the specular reflection light (SCE (Specular Component Included) Component Excluded) is switched to reflective light measurement. [0002] In addition, in the following description, the reflected light measurement under the condition (SCI) including the specularly reflected light from the sample will also be referred to as the SCI measurement, and the reflected light measurement under the condition (SCE) excluding the specularly reflected light will be referred to as the SCE determination. Background technique [0003] In recent years, the accuracy requirements for color management of industrial products have increased, and on the other hand, parts with complex minute shapes are mass-pro...
