The present disclosure is directed to providing to a smart window system capable of controlling a state of a display element (e.g., at least one of transparency, color, pattern, gradation degree, and displayed information) through various kinds of input devices and a control method thereof. In accordance with one aspect of the present disclosure, a smart window system may include a display element; an input device configured to receive a control command for the display element; and a controller configured to determine at least one of transparency, color, pattern, and gradation of the display element and information displayed on the display element on the basis of the control command.

Smart window system and control method therefor

One aspect of the present invention is to provide an electronic apparatus which is configured to provide a color writing function by means of the physical force of an external input means, and a control method thereof. More particularly, the present invention is to provide an electronic apparatus equipped with a plurality of liquid crystal panels in an electronic apparatus so that a plurality of colors can be written by the physical force of an external input means, and a control method thereof.

Electronic apparatus and control method thereof

A method for controlling an image forming apparatus is disclosed. An image pattern is developed both by a DC developing process using a developing bias voltage of only a DC voltage and by an AC+DC developing process using a developing bias voltage of a DC voltage overlapped with an AC voltage. The densities of the two developed image patterns is compared with each other to implement toner density control.

Method for controlling image forming apparatus

An image forming apparatus equipped with an improved developer detecting device and agitating device to simplify an inner structure of a developing device and/or a waste developer container while reducing the number of components and costs. The image forming apparatus includes a developer storage part to store a developer, a light emitting part and a light receiving part provided to detect an amount of developer stored in the developer storage part, and a rotating unit which rotates to agitate the developer stored in the developer storage part and guides light emitted from the light emitting part to the light receiving part. The rotating unit includes two rotating members. Each of the rotating members has a rotating shaft portion and an extending portion which extends eccentrically from the rotating shaft portion. The extending portions oppose each other to define a developer detecting region therebetween. When the rotating unit rotates, the developer detecting region moves upward and downward. Accordingly, the amount of developer stored in the developing device or the waste developer container can be checked more precisely.
