Abstract
Provided is a change degree deriving device including a receiving unit that receives an image obtained by capturing a known color body and an object while focusing on the object, the known color body including plural of color samples, each of which has a known color numerical value, and a detection image, and a detecting unit that detects a focus deviation of the color samples in the image, based on the detection image.
Claims7
A change degree deriving device comprising:
- a receiving unit that receives an image obtained by capturing a known color body and an object while focusing on the object, the known color body including a plurality of color samples, each of which has a known color numerical value, and a detection image;
- and
- a detecting unit that detects a focus deviation of the color samples in the image, based on the detection image.
A change degree deriving system comprising:
- a known color body that includes a plurality of color samples, each of which has a known color numerical value, and a detection image;
- an image capturing device that captures the known color body and an object while focusing on the object;
- and
- a detecting unit that detects a focus deviation of the color samples in data obtained by the image capturing device, based on the detection image.
A non-transitory computer readable medium storing a program causing a computer to execute a process for deriving change degree, the process comprising:
- receiving an image obtained by capturing a known color body and an object while focusing on the object, the known color body including a plurality of color samples, each of which has a known color numerical value, and a detection image;
- and
- detecting a focus deviation of the color samples in the image, based on the detection image.
