Abstract: An example of an information processing system sets an image capturing direction of a virtual camera in accordance with an image capturing direction of a camera, and if the image capturing direction of the camera is within a predetermined range, moves a virtual door in a virtual space in accordance with the image capturing direction of the virtual camera. If the image capturing direction of the camera is directed more upward than a first threshold, the information processing system does not move the virtual door further in the up direction. If the image capturing direction of the camera is directed more downward than a second threshold, the information processing system does not move the virtual door further in the down direction.

Abstract: A virtual reference plane and a virtual camera are updated based on detection of a characteristic portion in a captured image. A virtual object and the virtual camera are updated based on a shooting state. An overlay image in which an image of the virtual object is overlaid on the captured image is generated. The virtual camera and the virtual object are controlled such that the virtual object is in a field-of-view range, before the detection of the characteristic portion. The virtual object, the virtual reference plane, and the virtual camera are updated such that the virtual object is along the virtual reference plane, based on the shooting state, after the detection of the characteristic portion, and such that an appearance of the virtual object is in association with the shooting state, no matter whether or not the characteristic portion has been detected, when a position fixation condition is satisfied.

Abstract: An example information processing apparatus including an infrared light emitter capable of emitting infrared light and a camera capable of at least taking an infrared light image is provided. In the information processing apparatus, first, an image taken by use of the camera is obtained. A face detection process based on the image is repeatedly executed. Then, based on a result of the face detection process, emission of the infrared light is stopped and emission of the infrared light is resumed after a lapse of a predetermined time period.

Abstract: An example information processing apparatus including an infrared light emitter capable of emitting infrared light and a camera capable of at least taking an infrared light image is provided. In the information processing apparatus, when face detection has been successful with the infrared light emitted, emission of the infrared light is stopped, and a face detection process with the emission stopped is executed. As a result, when face detection has been successful, the face detection process is continued with emission of the infrared light stopped, and when face detection has been failure, the infrared light is emitted and the face detection process is continued.
