Systems and methods for adjusting light emitted from a display of a device are provided. The adjusting includes obtaining, from light of an environment detected by at least one sensor, a measured color of light of the environment, and obtaining, from light of the environment detected by at least one sensor, a measured brightness of light of the environment. In response to the obtaining the measured color and the measured brightness of light, a color of light emitted from the display is adjusted from an initial color prior to the adjusting to a target color that matches the measured color. Further, a brightness of light emitted from the display is adjusted from an initial brightness emitted by the display prior to the adjusting to a target brightness that matches the measured brightness of light.

A device for automatic control of color tone of a reel of thread includes a frame supporting an arm on which a reel of thread is loadable, a meter configured to project a measuring beam onto a cylindrical portion of the reel of thread, the meter having a camera and an illuminator aligned with the camera, the illuminator being multispectral and configured to illuminate the reel of thread with different wavelengths. A computer provided with a screen with graphic interface and connected to the meter processes the classification of the reel of thread loaded on the arm on the basis of measurements performed by the meter.

An artificial tooth manufacturing information generation method is provided. The artificial tooth manufacturing information generation method may include the steps of: photographing a target tooth to acquire a primary image; correcting the primary image to acquire a secondary image; selecting an area including the target tooth from the secondary image to extract a tertiary image; selecting a noise area caused by reflected light from the tertiary image and then correcting the noise area, to acquire a quaternary image; and generating artificial tooth manufacturing information by using a pixel value of the target tooth included in the quaternary image.

An adaptor for use with a colour measuring device is provided where the colour measuring device has a cavity, a sensor positioned at a closed end of the cavity for measuring colour of a surface, and a rim surrounding an open end of the cavity. The adaptor includes a plate for contacting the surface and covering the rim of the colour measuring device, the plate having a portion for occluding the cavity that is transparent, referred to as the transparent portion, and a releasable coupling mechanism fixed to the plate for coupling the plate to the colour measuring device such that the transparent portion of the plate covers the sensor of the colour measuring device.

A colorimetry device includes an integrating sphere having a measurement opening part and a trap hole, a trap disposed to be able to open and close the trap hole, a lid that is non-reflective and disposed to be able to open and close the trap hole, an imaging means disposed at a position that allows taking, through the trap hole, an image of a specimen facing the measurement opening part, and a display means that displays an image taken by the imaging means. The trap is to move to a position at which the trap hole is closed by the trap at a time of measurement of light with an SCI method, the light being reflected from the specimen, and the lid is moved to a position at which the trap hole is closed by the lid at a time of measurement of the light with an SCE method.
