20130084555 | INFORMATION PROVIDING SYSTEM - An information providing system is configured to provide each of students with an image of a material taken with a camera of an information providing device and allow interaction with the student. The teacher operates a tablet to set a plurality of answer options as available response choices for a question, such that the number of answer options is equal to or less than the number of answer buttons provided on each response clicker. The response clicker receives answer options specification data for specifying the answer options set by the teacher and provides initial notification that notifies each of the students of the answer buttons respectively corresponding to the plurality of answer options specified by the received answer options specification data. | 04-04-2013 |
20130084553 | INFORMATION PROVIDING SYSTEM - In an information providing system, a transmitter/receiver of an information providing device serves as a relay station to allow wireless data transmission and reception between the information providing device and a tablet and between the information providing device and each of response clickers provided for individual responders in audience. The information providing device wirelessly receives data from the tablet and from each individual response clicker in a specified time interval of data transmission after transmission of a transmission approval. The information providing device transmits the transmission approval to a transmitter/receiver of the tablet at a higher frequency than a frequency of transmitting the transmission approval to a transmitter/receiver of each of the response clickers. This effectively increases accumulation of the time interval of data transmission from the tablet to the information providing device. | 04-04-2013 |
20130022342 | IMAGING DEVICE AND CONTROL METHOD THEREOF - An imaging device moves a zoom lens, so as to change the magnification of an image of a subject, and obtains a near limit position of a focusing lens to the subject at a zoom lens position. When a target position of the focusing lens, which is required to keep the image in focus after the zoom lens is moved, is located on a near side, i.e., on an imaging plane side, of a threshold position determined based on the obtained near limit position, focus control is performed to move the focusing lens and thereby focus. When the target position of the focusing lens is not located on the near side but is located on a subject side of the threshold position, on the other hand, focus control is performed to move the zoom lens to a wider position and subsequently move the focusing lens to focus the image. | 01-24-2013 |
20120162444 | INFORMATION PROVIDING SYSTEM - An information providing system includes an information providing device and a tablet terminal. The information providing device wirelessly sends first information including a taken image, to the tablet terminal; wirelessly receives second information including information regarding a user's drawing operation on the table terminal, from the table terminal; and displays a drawn image corresponding to the user's drawing operation to be superimposed on the taken image, as a displayed image on a display, based on the second information. The tablet terminal includes an operation unit having an operating surface, on which the user performs the drawing operation. The tablet terminal wirelessly sends the second information to the information providing device, based on the user's drawing operation; wirelessly receives the first information from the information providing device; and displays a composite image including the drawn image superimposed on the taken image, on the operating surface, based on the first information. | 06-28-2012 |
20120139836 | INFORMATION PROVIDING DEVICE - An information providing apparatus equipped with a camera includes: an imaging unit configured to take an image of a preset area with the camera and obtain the taken image; a display output module configured to display the taken image as a displayed image on an image display device; a receiver configured to wirelessly receive operating information, which regards a user's operation performed via a pointing device and includes at least coordinates-related information, from the pointing device; and an operating information processor configured to perform processing based on the received operating information and display result of the processing to be superimposed on the displayed image, wherein the imaging unit, the display output module, the receiver and the operating information processor are all accommodated in a single housing. | 06-07-2012 |
20120130720 | INFORMATION PROVIDING DEVICE - An information providing device takes an image of a predetermined area and obtains the taken image in the form of image data, while externally obtaining voice data representing speech. The information providing device obtains text in a preset language corresponding to the speech in the form of text data, based on the obtained voice data, generates a composite image including the taken image and the text in the form of composite image data, based on the image data and the text data, and outputs the composite image data. | 05-24-2012 |
20110317063 | EXPOSURE CONTROL APPARATUS AND EXPOSURE CONTROL METHOD - An exposure control apparatus does exposure control using an exposure evaluation value EV (pv) and an exposure target value EV (sp) according to brightness signals in an exposure adjustment range ER by a plurality of exposure adjustment units. The deviation EV (err) of the exposure target value EV (sp) and the exposure evaluation value EV (pv) is found, and when the deviation EV (err) is in a steady state of a specified level or less, and exposure control is done in a gain exposure control range ER-g, the gain exposure adjustment unit | 12-29-2011 |
20110181745 | PRESENTATION SYSTEM - The presentation device comprises an image capture portion for capturing an image, and a transmission portion for wireless serial transmission of the captured images. The image output device comprises a reception portion for wireless serial reception of the images from the presentation device, an output portion for outputting the received images, and a measurement portion for measuring wireless signal strength. The output portion compares the signal strength with a threshold value established through an operation by the user, and if the signal strength exceeds the threshold value, serially outputs the images serially received by the reception portion so as to outputs a moving image, or if signal strength is equal to or less than the threshold value, continuously outputs a single previously received image so as to outputs a still image. | 07-28-2011 |
20110181736 | PRESENTATION DEVICE - The presentation device comprises an operation receiving portion adapted to receive an operation for setting a shooting parameter for the purpose of capturing an image, an image capture portion for capturing an image based on the shooting parameter, a transmitting portion for transmitting the captured image wirelessly to an image output device, and a detecting portion for detecting wireless connection status. The operation receiving portion suspends reception of the operations if the detecting portion detects a lost wireless connection. | 07-28-2011 |
