INFORMATION PROCESSING APPARATUS, PROGRAM, AND INFORMATION PROCESSING METHOD

Provided is an information processing apparatus that is to enhance determination accuracy in determining a front-and-rear relationship between positions where occupants are seated, from a captured image acquired by capturing an inside of a vehicle cabin. A server apparatus 100 includes: a detection section 131 that detects a face image of an occupant riding in a vehicle 3, from a captured image of an inside of a vehicle cabin of the vehicle 3; and a determination section 133 that, when a plurality of face images are detected, determines a front-and-rear relationship between positions where respective occupants corresponding to the face images are seated, by comparing each of areas of the detected face images with a determination threshold value, wherein the determination section 133 divides the captured image, in a direction parallel to a longitudinal direction of the vehicle 3, into a first segment 31 including a driver seat and a second segment 33 including a front passenger seat and, when the plurality of face images are detected in the first segment 31 or the second segment 33, determines the front-and-rear relationship between the positions where the respective occupants corresponding to the face images are seated, by comparing each of the areas of the face images with the determination threshold value.
