Abstract:
PROBLEM TO BE SOLVED: To provide an image sensor capable of measuring luminous intensity, proximity, and color temperature that can measure current luminous intensity, proximity to an object, and color temperature of the object by using a variation in an output voltage value according to the existence or absence of infrared and visible ray with a wavelength in a specific band. SOLUTION: The image sensor capable of measuring the luminous intensity, proximity, and color temperature includes separate second sensing portions that are provided around a first sensing portion having an image pixel and are configured to operate separately from the first sensing portion, thus making it possible to reduce power consumption and to easily measure current luminous intensity, proximity to an object, and color temperature of the object.

Abstract:
PROBLEM TO BE SOLVED: To improve a scanning device that is used for color measurements so as to be suitable for high-accuracy measurements without making any contact. SOLUTION: A support surface for the measured object, a drive unit for moving the color measuring head above the support surface in at least one-dimensional direction and for adjusting the height of the color measuring head in the direction perpendicular to the support surface, and a measurement and drive control unit which drives the drive unit and cooperates with the color measuring head are included. An electronic distance control system which adjusts the distance of the color-measuring head above a measurement point in a direction perpendicular to the support surface to a desired measuring distance for each measurement point by using the drive unit is also included. The scanning device is suitable for performing high-accuracy measurements above even the smallest measurement areas without contact, and further a separate measurement sensor is not needed for the distance control system.

Abstract:
PROBLEM TO BE SOLVED: To provide a hand-held color measuring device which can be easily used for all purposes such as calibration measurement or reference measurement of a white tile or a reference color field with no difficulty in handling and therefore requires no accessories. SOLUTION: The hand-held color measuring device includes: a housing containing a photoelectron measuring section for creating digital measurement data that characterizes the color of a measuring object; and passive elements which can be selectively positioned in a measurement beam path of the photoelectron measuring section and which are necessary for realizing various applying functions such as a measurement window and a reference standard. The passive elements are positioned in a first housing block (100), and the whole photoelectron measuring section is positioned in a second housing block (200). The second housing block (200) can be adjusted in a plurality of predetermined applicable positions with respect to the first housing block. Each of the applicable position keeps each of the passive elements is disposed in the measurement beam path of the photoelectron measuring section. This makes it possible to easily realize a compact color measuring device which is divided especially into two housing blocks adjustable with respect to each other and which is suitable to a large number of applying functions.
