Abstract
An image processing device performing image processing on images obtained by shooting an object to be monitored at a plurality of time points. The image processing device includes a hardware processor that performs a process of removing, from image data indicating the images, second frequency component data that is lower in frequency than first frequency component data indicating a luminance of the object to be monitored, the second frequency component data indicating a background luminance change of the object to be monitored.
Claims19
An image processing device for performing image processing on images obtained by shooting an object to be monitored at a plurality of time points, the image processing device comprising:
- a hardware processor that performs a process of removing, from image data indicating the images, second frequency component data lower in frequency than first frequency component data indicating a luminance change of the object to be monitored, the second frequency component data indicating a background luminance change of the object to be monitored.
An image processing method comprising:
- acquiring image data indicating images obtained by shooting an object to be monitored at a plurality of time points;
- and
- performing a process of removing, from the image data, second frequency component data lower in frequency than first frequency component data indicating a luminance change of the object to be monitored, the second frequency component data indicating a background luminance change of the object to be monitored.
A non-transitory recording medium storing a computer readable image processing program for causing a computer to execute:
- acquiring image data indicating images obtained by shooting an object to be monitored at a plurality of time points;
- and
- performing a process of removing, from the image data, second frequency component data lower in frequency than first frequency component data indicating a luminance change of the object to be monitored, the second frequency component data indicating a background luminance change of the object to be monitored.
