摘要： An image display apparatus for displaying a 3D video signal using a liquid crystal device such as an HTPS or LCOS device comprises a frame rate converter (3) that converts the input video signal to a doubled frame rate, a signal format converter (4) that converts the pixel sequence of the video signal, a light source controller (7) that outputs a light source control signal for turning the light source used for image display on and off, and a 3D glasses controller (8) that generates a glasses control signal (c3) for shutters (64R, 64L) that switch the transmission of the light to the right and left eyes of 3D glasses (64). The risk of crosstalk between the right and left images, due to device response speed is reduced, without requiring a large number of frame memories.

摘要： In a constant current switching power supply, the current flowing through the load, is feedback-controlled based on the deviation of the detection value (Id) from the target value (Ir), multiplied by a proportional gain (PG), the value of the gain is set to a predetermined value immediately after the load switching element (5) is turned on, and is thereafter gradually reduced with elapse of time. When the current to the load (4) is supplied by a PWM controlled switching circuit (1), the PWM signal is determined based on a product of the deviation and a proportional gain. It is possible to shorten the rise time of a pulsative load current in a situation where the current is relatively large.

摘要： A power converting unit supplies a predetermined current to each of light-emitting elements by controlling a duty ratio of a semiconductor switching element. A light-emitting-element selecting unit sequentially selects a light-emitting element to be supplied with the current from the power converting unit. A duty-ratio control unit controls the duty ratio of the semiconductor switching element based on a value obtained by multiplying a gain by a difference between an output current of the power converting unit and a target current. A gain selecting unit changes the gain according to selected light-emitting element.

摘要： A field sequential color display is obtained by successive display of a sequence of monochrome images of different colors. Monochrome images in at least one of the colors are displayed with light of two different brightness levels, the light of the lower brightness being used to display comparatively low gray levels, the light of both the lower and higher brightness levels being used to display comparatively high gray levels. This scheme provides extra resolution at the low end of the gray scale, and increases the number of displayable gray levels by counteracting the loss of gray levels that occurs due to gamma correction.
