Abstract

Official abstract text for this publication.

An inspection method includes: spectroscopically separating light from a predetermined imaging range of an inspection object into light of a plurality of wavelengths and imaging spectroscopic images of each of the wavelengths; inspecting a shape of the inspection object using the spectroscopic image of a predetermined wavelength among the wavelengths imaged in the imaging of the spectroscopic images of each of the wavelengths; and inspecting a color of the inspection object using the spectroscopic images of each of the wavelengths imaged. The predetermined wavelength is determined so that a maximum light quantity of the light from the inspection object in the corresponding spectroscopic image at the predetermined wavelength is equal to or higher than maximum light quantities in the other spectroscopic images at the other wavelengths.

First claim

Opening claim text (preview).

What is claimed is: 1. An inspection method for causing a processor to execute a program stored in a memory, the method comprising executing on the processor the steps of: spectroscopically separating light from a predetermined imaging range of an inspection object into light of a plurality of wavelengths and imaging spectroscopic images of each of the wavelengths; inspecting a shape of the inspection object using the spectroscopic image of a predetermined wavelength among the wavelengths imaged in the imaging of the spectroscopic images of each of the wavelengths; and inspecting a color of the inspection object using the spectroscopic images of each of the wavelengths imaged, wherein the predetermined wavelength is determined so that a maximum light quantity of the light from the inspection object in the corresponding spectroscopic image at the predetermined wavelength is equal to or higher than maximum light quantities in the other spectroscopic images at the other wavelengths. 2. An inspection apparatus comprising: a spectroscopic image sensor component configured to spectroscopically separate light from a predetermined imaging range of an inspection object into light of a plurality of wavelengths and image spectroscopic images of each of the wavelengths; a memory configured to store a program; and a processor configured to execute the program so as to: inspect a shape of the inspection object using the spectroscopic image of a predetermined wavelength among the wavelengths; and inspect a color of the inspection object using the spectroscopic images of each of the wavelengths, wherein the predetermined wavelength is determined so that a maximum light quantity of the light from the inspection object in the corresponding spectroscopic image at the predetermined wavelength is equal to or higher than maximum light quantities in the other spectroscopic images at the other wavelengths. 3. A computer readable non-transient medium storing instructions to cause one or more processors to: cause a spectroscopic image sensor component to spectroscopically separate light from a predetermined imaging range of an inspection object into light of a plurality of wavelengths and image spectroscopic images of each of the wavelengths; inspect a shape of the inspection object using the spectroscopic image of a predetermined wavelength among the wavelengths; and inspect a color of the inspection object using the spectroscopic images of each of the wavelengths, wherein the predetermined wavelength is determined so that a maximum light quantity of the light from the inspection object in the corresponding spectroscopic image at the predetermined wavelength is equal to or higher than maximum light quantities in the other spectroscopic images at the other wavelengths.
