Abstract
An output device includes: an acquisition part that acquires a first image covering excrement captured by a camera to photograph an inside of a bowl of a toilet; a dividing part that divides the acquired first image into a plurality of divisional areas; a calculation part that calculates an area representative value including a representative value of each of the color components of each of the divisional areas; and an output part that outputs the calculated area representative value.
Claims13
An output device for outputting information about excrement, comprising:
- a processor;
- and
- a memory, wherein
- the processor is configured to:
- acquire a first image covering the excrement captured by a camera to photograph an inside of a bowl of a toilet, the first image containing one or more color components;
- detect whether the first image contains an image of the excrement;
- divide the acquired first image into a plurality of divisional areas;
- calculate an area representative value including a representative value of each of the color components of each of the divisional areas;
- and
- output the calculated area representative value, wherein
- the dividing operation divides the first image by a predetermined number of pixels in a vertical direction and a horizontal direction, into the divisional areas containing pixels of the excrement when the detecting operation detects that the first image contains the image of the excrement,
- a pixel value of each of all pixels included in each of the divisional areas is set to the area representative value corresponding to each of the divisional areas, and
- the calculating operation calculates an area representative value of the divided divisional areas using only pixels of the excrement for the divided divisional area containing a contour of the image of the excrement, and
- the processor is further configured to:
- acquire a second image not covering the excrement captured by the camera;
- extract, from the acquired second image, a pixel group including pixels constituting a drain hole of the toilet, the pixel group being calculated in advance through calibration;
- and
- remove the pixel group from the first image, and divide the first image subjected to the removal into a plurality of divisional areas.
