Abstract: A determination device includes an image information acquirer configured to acquire image information of a subject image obtained by photographing an internal space of a toilet bowl in excretion; an estimator configured to perform estimation regarding a determination matter relating to excretion by inputting the image information to a learned model, the learned model having learned a correspondence relationship between an image for learning and a determination result of the determination matter relating to excretion, the learned model learned by machine learning using a neural network, the image for learning representing an internal space of a toilet bowl in excretion; and a determiner configured to perform determination regarding the determination matter of the subject image based on an estimation result obtained by the estimator.

Abstract: A human body detection sensor includes: a detection decision unit that decides whether a state is a detection state or a non-detection state of a detection target; a specular reflection decision unit that decides whether or not reflected light that is incident onto a line sensor is specularly-reflected light; and a continuation decision unit that decides whether or not a state in which the detection target exists is ongoing, wherein, when specularly-reflected light is detected while a determination is made indicating the detection state, the detection decision unit keeps the result of a determination indicating the detection state without change if the result of the decision by the continuation decision unit indicates that the state is ongoing and changes the determination to a determination indicating the non-detection state if the result of the decision shows any other states.

Abstract translation: 人体检测传感器包括：检测判定单元，判定状态是检测对象的检测状态还是非检测状态; 判定入射到线传感器上的反射光是否是镜面反射光的镜面反射判定单元; 以及连续判定单元，其判定存在检测对象的状态是否正在进行，其中，当在作出指示检测状态的判定时检测到镜面反射光时，检测决定单元保持测定结果 如果所述连续判定单元的决定结果指示状态正在进行，并且如果所述判定结果显示任何其他状态，则将所述确定改变为指示所述非检测状态的确定，而不改变所述检测状态。
