Abstract
There is provided with an image processing apparatus. An obtaining unit obtains a visible light image and an invisible light image of an imaging region. A first evaluation unit evaluates a brightness of the imaging region. A second evaluation unit evaluates noise in an object in the imaging region. A combining unit generates a combined image by combining the visible light image and the invisible light image. An output unit outputs either the combined image or the invisible light image in accordance with an evaluation result on the noise without outputting the visible light image in response to the brightness becoming lower than a first threshold during an operation of outputting the visible light image.
Claims18
An image processing apparatus comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor and storing instructions that, when executed by the processor, cause the at least one processor to function as:
- an obtaining unit configured to obtain a visible light image and an invisible light image of an imaging region;
- a first evaluation unit configured to evaluate a brightness of the imaging region;
- a second evaluation unit configured to evaluate noise in the imaging region;
- a combining unit configured to generate a combined image by combining the visible light image and the invisible light image;
- and
- an output unit configured to, in a case where the brightness becomes lower than a first threshold during an operation of outputting the visible light image:
- output the combined image in a case where a noise evaluation value that is an evaluation result by the second evaluation unit is not less than a second threshold;
- and
- output the invisible light image in a case where the noise evaluation value is less than the second threshold.
An image processing method comprising:
- obtaining a visible light image and an invisible light image of an imaging region;
- evaluating a brightness of the imaging region;
- evaluating noise in the imaging region;
- generating a combined image by combining the visible light image and the invisible light image;
- and
- in a case where the brightness becomes lower than a first threshold during an operation of outputting the visible light image;
- outputting the combined image in a case where a noise evaluation value that is an evaluation result is not less than a second threshold;
- and
- outputting the invisible light image in a case where the noise evaluation value is less than the second threshold.
A non-transitory computer-readable medium storing a program which, when executed by a computer comprising a processor and a memory, causes the computer to perform:
- obtaining a visible light image and an invisible light image of an imaging region;
- evaluating a brightness of the imaging region;
- evaluating noise in the imaging region;
- generating a combined image by combining the visible light image and the invisible light image;
- and
- in a case where the brightness becomes lower than a first threshold during an operation of outputting the visible light image;
- outputting the combined image in a case where a noise evaluation value that is an evaluation result is not less than a second threshold;
- and
- outputting the invisible light image in a case where the noise evaluation value is less than the second threshold.
