Abstract: A display apparatus includes circuitry to receive hand drafted data input by an electronic pen; display, on a screen, a plurality of character string candidates converted in a recognition language from the hand drafted data; and display a converted character string converted from one of the plurality of character string candidates, selected by the electronic pen, into a target language associated with identification information of the electronic pen. The target language is different from the recognition language. In response to selection of the converted character string, the circuitry displays a plurality of character string candidates in the recognition language corresponding to the converted character string.

Abstract: An image projector includes: a light source to emit light; an image forming element irradiated with the light from the light source and to form an image for projection onto a projection surface; a first controller activated when the image projector is in a waiting state; and a second controller that is not activated when the image projector is in the waiting state. In response to detection of an execution request for executing the image projector in the waiting state at the first controller, the first controller sets a power supply circuit with an initial voltage to start supplying power to the light source, and when the light source is lighted at the initial voltage, activates the second controller.

Abstract: An image projector includes a light source to emit light, an image forming device to form an image based on a reflected light of the light emitted from the light source, a color wheel disposed between the light source and the image forming device so as to pass the light emitted from the light source to the image forming device through an optical path, the color wheel including a plurality of color filters, at least one lens to project the image formed on the image forming device to a projection surface as a projection image, and circuitry to cause the color wheel be moved away from the optical path for the light emitted from the light source, when a brightness of the projection image is to be increased.

Abstract: A projector includes a projection unit to project an image on a screen; an angle detector to detect shaking of the projection unit; and a trapezoidal distortion correction unit to conduct automatic trapezoidal distortion correction of the image displayed on the screen based on an inclination angle of the projection unit detected by the angle detector, and to enable manual trapezoidal distortion correction of the image displayed on the screen. When the manual trapezoidal distortion correction is conducted after the automatic trapezoidal distortion correction, the trapezoidal distortion correction unit determines whether an angle deviation of the inclination angle exceeds for a given threshold angle for a given time period. When the trapezoidal distortion correction unit determines that the angle deviation exceeds the given threshold angle, the automatic trapezoidal distortion correction is conducted again.

Abstract: A device, method, and program stored in a recording medium are provided. A sampling time period and, a value of limit angle are set. Inclination of the projector device is detected with respect to a horizontal surface to output a plurality of inclination angle values of the projector device. A representative angle value of a current sampling time period is calculated based on the plurality of inclination angle values and the difference between the representative angle value and a representative angle value from a previous sampling time period is calculated. It is determined whether the difference in representative angle value is equal to or greater than the limit angle value to generate a determination result. Finally, trapezoidal distortion in the image is corrected based on the inclination angle values detected when the determination result indicates that the difference is equal to or greater than the limit angle value.
