There is provided a camera of which operability is good regardless of the brightness of the surrounding environment. The brightness of the surrounding environment is detected by a brightness detection unit provided in a camera. The contents of settings of the camera are displayed on a sub-display 18 in a situation in which the surrounding environment is bright. The contents of settings of the camera and an image representing the set state of a shutter speed dial 33 are displayed on the sub-display 18 in a case in which the surrounding environment is dark.

A camera includes a viewfinder portion causing a frontward field of view to be visible through a viewfinder, and a drive lever rotatable about a shaft. An operation cylinder operable to extend and contract an extendable unit includes a guide surface extending in a circumferential direction and a recess adjacent to the guide surface. The drive lever includes an actuation portion that comes in contact with the guide surface of the operation cylinder. The camera further includes an urging member urging the actuation portion in the drive lever, a prism that changes a direction of a field of view visible through the viewfinder portion, and a prism guide lever rotatable about a shaft. The prism guide lever includes a prism holder holding the prism, and a follower gear meshing with a drive gear in the drive lever. The prism holder is placeable into the viewfinder portion.

A mobile terminal includes a terminal body and a camera module. The terminal body includes a housing and a control module. The housing is provided with a viewfinder window. The camera module includes a lens component and an image sensor. The lens component includes a lens frame, a concave lens, and a convex lens. The image sensor is fixed inside the housing and is located at a side of the convex lens away from the concave lens. The image sensor is electrically connected to the control module so as to control the image sensor using the control module to recognize an object image from outside of the viewfinder window.

[Object] To provide an information processing device, an information processing method, and a program. [Solution] An information processing device including: an acquisition unit configured to acquire attention information regarding an attention target of a user; and a zoom control unit configured to perform zoom control of a camera on the basis of non-zoom control of the camera and the attention information when the non-zoom control is performed on the basis of the attention information.

A method and an apparatus to provide a service using a sensor and image recognition in a portable terminal that supports Augmented Reality (AR). The method includes determining whether the portable terminal is parallel to ground using an acceleration sensor. When the portable terminal is parallel to the ground, either a map including nearby Point Of Interest (POI) information or constellation information is displayed.
