Abstract: An image display apparatus includes a controller for dividing at least a portion of an image displayed based on a digital video signal, into a plurality of image areas defined by display lines, and establishing different delays for the divided image areas, a clock adjuster generating a clock in synchronism with the dot clock, delaying a phase of the clock according to the delays established by the controller, for the respective divided image areas, and outputting the delayed clock as the reproduced dot clock, and a delay evaluating unit converting differential data between adjacent signal levels into absolute values and accumulatively adding the absolute values based on the reproduced dot clock output from the clock adjuster, with respect to the display lines which define the divided image areas, thereby producing accumulated sums. The controller judges the delay established for the divided area with the maximum accumulated sum, as optimum.

Abstract: An image distortion correction method is provided which is capable of correcting for distortion of a projected image by designating an arbitrary correction point by using a simple and easy operation without independently providing a display device and/or a pointing device.

Abstract: A display device uses a field sequential color scheme. Assume that a panel video writing period defines a period from the start of writing image data into a display panel to the completion of displaying the image on the basis of the image data in a sub-frame. A light source driving circuit generates a driving signal for gradually increasing the luminance of a light source of a color corresponding to a displayed image in the present sub-frame from zero to a predetermined value within the panel video writing period of the present sub-frame and for gradually decreasing the luminance of the light source from the predetermined value to zero within the panel video writing period of the next sub-frame. A light source driver drives the light source to emit light in accordance with the driving signal.

Abstract: An illumination apparatus used in non-light emission transparent display devices includes a base material, light emitting elements arranged two dimensionally on the surface of the base material, a drive section driving the light emitting elements, and a light emitting intensity control section controlling a light emitting intensity of the light emitting elements. An arrangement of the light emitting elements is such that a density at ends of the base material is high compared to that in a center part thereof, and the ends have a high density in regions where the base temperature is high and the center part has a high density in regions where the base material temperature is high.

Abstract: A display apparatus is capable of displaying a distortion-free projected image based on an image signal from a computer. The display apparatus receives an image signal from the computer and projects an image depending o the image signal onto a projection surface. The display apparatus includes a setting section which sets identification information representative of an aspect ratio of a display of the computer. The identification information set in the setting section can be changed by the user.

Abstract: Spiral springs (20) pressing a lift member (30) in an upward direction is arranged so that wound-up portions (20b) thereof move up and down along lift paths (13a, 13b) according as the lift member (30) moves up and down. In each lift path (13a, 13b) is provided a push-fit portion (40) of which a width is narrower than an outer diameter of the wound-up portion (20b) of the spiral spring (20), and in which according as the lift member (30) is lowered, the wound-up portion (20b) is fitted in such a manner that the wound-up portion becomes radially compressed. Accordingly, a cost-efficient and universally applicable display elevation adjusting apparatus can be provided which can make the operation feeling at the time of raising adjustment constant and can attain adjustment to suit the preference.

Abstract: An apparatus of the present invention for displaying an image comprises connected device controller 22 for notifying one of a plurality of apparatuses S1 to Sn for transmitting an image connected via a network 99 and that has made a first connection request after activation, of information that display authority that is a right to preferentially perform processing for displaying an image is granted and of information that image data may be transmitted at any time, and for notifying another one or more of the plurality of apparatuses for transmitting an image and that have made a connection request, of information that image data cannot be transmitted unless permitted.

Abstract: A driving method includes: dividing a unit period into a plurality of sub-frame periods corresponding to the primary colors; writing a primary color component in each sub-frame period by a first scan executed on the plurality of pixels; irradiating, in each sub-frame period, the plurality of pixels with the corresponding primary color of light by the irradiation unit at a timing that is after the first scan and before the first scan of a subsequent sub-frame period; and waiting a wait period that is from when the first scan of one primary color component among the at least three colors ends until when the irradiation unit starts irradiating the one primary color of light, the wait period for the one primary color being different from wait periods for the other colors.

Abstract: A PC activates a software program for detecting when a network terminal device is connected to a network, based on the control action of the user. When the network terminal device is connected to the network, the network terminal device sends a connection signal to the PC, and then operates as a DHCP server. Having received the connection signal, the PC recognizes an IP address of the network terminal device that is included in the connection signal, and operates as a DHCP client. The PC makes its own network setting using an IP address assigned from a DHCP server that has the same IP address as the IP address of the network terminal device.
