A wearable information processing apparatus comprising: a power generation device , a power storage device , a determination unit configured to determine whether environmental information of an environment of the power generation device is to be recorded, on the basis of both of a power generation amount (P) of power generated by the power generation device and a power storage amount (Q) of power stored in the power storage device that stores the power generated by the power generation device ; an imaging device ; and a processing unit configured to record the environmental information in a recording medium by carrying out a process relating to the recording of the environmental information, in a case where it is determined that the environmental information is to be recorded, characterized in that the determination unit determines that the environmental information is to be recorded in a case where the power generation amount (P) is greater than or equal to a power generation amount threshold (p) and where the power storage amount (Q) is greater than or equal to a power storage amount threshold (q), or in a case where the power generation amount (P) is strictly greater than the power generation amount threshold (p) and the power storage amount (Q) is strictly greater than the power storage amount threshold (q), wherein, as the process relating to the recording of the environmental information, the processing unit is adapted to causes the imaging device to capture an image of the environment of the power generation device, and records information relating to the image capturing carried out by the imaging device as the environmental information in the recording medium, and wherein the information relating to the image capturing both of the image captured by the imaging device and information relating to time when the image has been captured. a power generation device , a power storage device , a determination unit configured to determine whether environmental information of an environment of the power generation device is to be recorded, on the basis of both of a power generation amount (P) of power generated by the power generation device and a power storage amount (Q) of power stored in the power storage device that stores the power generated by the power generation device ; an imaging device ; and a processing unit configured to record the environmental information in a recording medium by carrying out a process relating to the recording of the environmental information, in a case where it is determined that the environmental information is to be recorded, characterized in that the determination unit determines that the environmental information is to be recorded in a case where the power generation amount (P) is greater than or equal to a power generation amount threshold (p) and where the power storage amount (Q) is greater than or equal to a power storage amount threshold (q), or in a case where the power generation amount (P) is strictly greater than the power generation amount threshold (p) and the power storage amount (Q) is strictly greater than the power storage amount threshold (q), wherein, as the process relating to the recording of the environmental information, the processing unit is adapted to causes the imaging device to capture an image of the environment of the power generation device, and records information relating to the image capturing carried out by the imaging device as the environmental information in the recording medium, and causes the imaging device to capture an image of the environment of the power generation device, and records information relating to the image capturing carried out by the imaging device as the environmental information in the recording medium, and wherein the information relating to the image capturing both of the image captured by the imaging device and information relating to time when the image has been captured. <EOS>
