TECHNICAL FIELD

The present invention relates to a mobile terminal having an imaging unit and a display.

BACKGROUND ART

A mobile terminal of the related art, having an imaging unit (a camera) generally has a communication function, so that the mobile terminal is capable of transmitting images photographed by the camera to the outside through a telephone line or a network and is easy to share the images among users. Such a mobile terminal usually has a display such as a liquid crystal on a back surface, and a user holds the terminal when performing photographing by the camera, and can perform photographing while monitoring the images displayed on the display from a certain distance away during the photographing.

For example, Patent Documents 1 and 2 disclose such mobile terminals. On the other hand, in addition to such a display, an imaging apparatus such as a digital camera is an apparatus having an electronic viewfinder such that a user can observe the photographed images by looking into the electronic viewfinder. For example, Patent Document 3 discloses the electronic viewfinder.

SUMMARY OF THE INVENTION

Problems to be Solved by the Invention

However, the mobile terminals disclosed in Patent Documents 1 and 2 have a problem that external light is incident on a display in bright environments such as outdoors, making it difficult for the images on the display to be viewed. Further, the electronic viewfinder disclosed in Patent Document 3 is easy to shield light and easy to monitor images even in bright environments such as outdoors, whereas apparatuses having the electronic viewfinder has a problem that the apparatuses are difficult to be downsized and thin and in addition to the display, cost of electronic components of the electronic viewfinder is increased.

Accordingly, an object of the present invention is to control the display of a mobile terminal such that a viewer including a finder portion can be used for the mobile terminal.

Solutions to Problems

In order to solve the problems, the present invention adopts, for example, the configurations described in the claims. An example thereof is a mobile terminal in which an imaging unit is provided on a front surface side and a display unit and a sensor are provided on a back surface side, including: a signal processing unit which, from a signal output by the imaging unit, generates information to be displayed by the display unit; and a control unit into which a signal from the sensor is input and which controls the signal processing unit,

in which a display state of the display unit based on the control performed by the control unit includes a first display state for display in a first display region if no detection signal is being input from the sensor, and a second display state for display in a second display region if a detection signal is being input from the sensor.

Effects of the Invention

According to the present invention, it is possible to perform display suitable for a viewer including a finder portion, so that the viewer may be used for the mobile terminal.
