Abstract:
The present disclosure describes a projector which has: an image projection portion; an image provision portion that provides a projection image to the image projection portion; a deviation movement detection portion that detects a deviation movement of the image projection portion; and an image process portion that based on detection by the deviation movement detection portion, shifts the image provided by the image provision portion in a direction where the deviation movement is corrected. According to this, even if an image projection function does not include a deviation correction function, it is possible to perform the deviation correction by means of the image process.
Abstract:
A remote control signal receiver includes a receiving sensor to receive a remote control signal for remotely controlling an electrical apparatus, a receiving signal processor to judge whether or not the receiving sensor received the remote control signal, to recognize a direction included in the remote control signal and to generate an internal signal in response to the direction in accordance with the receiving signal, and an intermittent controller to drive the receiving sensor intermittently during a standby period of the electrical apparatus.
Abstract:
An electronic device includes a power supply system and a load circuit connected to the power supply system. The load circuit mutually switches between the first mode and the second mode. In the first mode, the load circuit operates with electric power supplied from the power supply system. On the other hand, in the second mode, the load circuit is brought into the state where the electric power does not need to be supplied from the power supply system. In response to the fact that the mode of the load circuit is switched from the first mode to the second mode, a power supply control device causes an AC/DC converter to stop.
Abstract:
A cooling system incorporates a semiconductor IC device having an abnormality detector for detecting the occurrence of an abnormal condition by receiving clock signals and more or less periodically outputted signals from a system being monitored. An AND gate receives the clock signals and generates sequentially increasing count signals. During a normal operation of the system, another AND gate receives the signals from the system being monitored. These signals serve to initialize the clock count signals. These signals are received under a normal condition of operation such that the count signal is initialized before reaching a specified value. An abnormality-indicating signal is outputted when the clock count number reaches the specified value. The AND gates are so connected that the first AND gate serves to prohibit input of clock signals, the second AND gate serves to stop initialization of the count signal when an abnormality indicating signal is received. The mode of operation of the system may be changed so as to reduce the rate of heat production when an abnormal condition is detected.

Abstract:
Technology for controlling image display according to the state of a viewer wearing eyeglasses to view 3D images is provided. When an inclined angle of eyeglasses is in a predetermined range, an image display device alternately displays a left-eye image and a right-eye image. When the inclined angle of the eyeglasses exceeds the predetermined range, the image display device does not switch the left-eye image with the right-eye image. For example, the image display device displays 2D images. Optical shutters of the eyeglasses are synchronized with the left-eye image and the right-eye image. When the image display device does not switch the left-eye image with the right-eye image, the optical shutters are both open.
Abstract:
A semiconductor integrated circuit device which requires high packaging density adopts a method for forming bumps in a terminal section of a semiconductor chip and bonding the semiconductor chip directly on a substrate. In this case, in order to prevent damage to the semiconductor integrated chip, which would otherwise be caused by bonding pressure employed at the time of bonding operation, non-connected dummy bumps are provided at corner sections of the semiconductor chip. Even when the dummy bumps are provided, there arises a necessity for preventing an increase in the size of the semiconductor chips, which would otherwise arise when the dummy bumps are provided on the chip.
Abstract:
An image processor for forming an easy-to-see image by broadening the significant band of image data received from a logarithmic (LOG) image sensor to enhance the contrast of the image. The LOG image sensor generates an output in response to the light, with the output voltage being a logarithm of the intensity of the light received. The image processor extracts only those pixel data in the significant band out the image data received from the LOG image sensor in accordance with the distribution of the voltage of the signals. In order to form an easy-to-see image, the processor expands the voltage band, assuming that the output voltage has a linear dependence on the intensity of light received by the LOG image sensor. The resultant image has an wider band in voltage, which enhances the contrast, and hence the visibility, of the image.

An electronic device (100) includes a power supply system (1) and a load circuit (2) connected to the power supply system (1). The load circuit (2) mutually switches between the first mode and the second mode. In the first mode, the load circuit (2) operates with electric power supplied from the power supply system (1). On the other hand, in the second mode, the load circuit (2) is brought into the state where the electric power does not need to be supplied from the power supply system (1). In response to the fact that the mode of the load circuit (2) is switched from the first mode to the second mode, a power supply control device (4) causes an AC/DC converter (7) to stop.
Abstract:
The invention provides a display apparatus having a temperature sensor and a step-up circuit generating a drive voltage of the display apparatus by stepping up a power source voltage. The temperature sensor provides temperature data indicative of the temperature of the display panel with a reduced measurement error without limiting the operation of the step-up circuit. To do so, in view of the fact that the step-up circuit has alternating active state in which the circuit is stepping up a source voltage to output a required step-up voltage and inactive state in which no stepping operation is made, the temperature sensor is adapted to obtain temperature data while the step-up circuit is inactive. The temperature data obtained is supplied to a temperature compensation means for changing the drive condition setting value that define the drive condition of the display panel to compensate for the temperature change.
