Abstract: According to one aspect of the invention, there is provided a mobile apparatus including: a plurality of input sections each configured to display at least one image that corresponds to an input value assigned thereto; a plurality of label areas provided correspondingly to the plurality of input sections, each of the label areas labeled with at least one characters associated with the input value that is assigned to a corresponding one of the plurality of input sections; a photosensor configured to measure ambient illuminance; and a display controller configured to control turn-off and turn-on of image-display at the plurality of input sections based on the ambient illuminance.

Abstract: An electronic apparatus includes: a luminance adjustable display module; an illuminance sensor configured to detect illuminance around the electronic apparatus; and a controller configured to: read the illuminance from the illuminance sensor; determine luminance corresponding to the illuminance; control the luminance adjustable display module to set luminance to the determined luminance; and set a waiting time based on the determined luminance, the waiting time being a time to a next time point of illuminance reading and luminance control. The controller is configured to set the waiting time short when the determined luminance is high and to set the waiting time long when the determined luminance is low.

Abstract: An electronic apparatus includes: at least two casings changeable in positional relationship between the at least two casings from a first state to a second state that is different from the first state; an input module configured to input a command by touch, a first detector configured to detect a start of a transition from the first state to the second state; a second detector configured to detect a completion of the transition; and an input controller configured to disable input through the input module in a time between the start detected by the first detector and the completion detected by the second detector.
