摘要： Embodiments relate to an organic EL panel comprising a panel driving circuit for converting R′G′B′W data into driving signals which is supplied to a pixel circuit. At a RGB→R′G′B′W converting section, the bit width of input RGB data is greater than the bit width of converted R′G′B′W, and the characteristic curve of the amount of luminescent of W sub pixel for the input data of W in the said panel driving circuit is different from the R′G′B′ curve normalized at a luminance ratio necessary for a reproduction of white color with sub pixels of RGB. An appropriate process is carried out by the RGB→R′G′B′W converting section in accordance with the curve of input data from the panel driving circuit verses amount of luminescent to minimize an error which may be generated when a conversion is made.

A display panel 12 is configured having unit pixels made up of subpixels of RGBW (red, green, blue, white).

摘要： An electronic still camera is provided with an electronic image sensor for generating an image signal corresponding to a still image of a subject and an orientation determination section for sensing the orientation of the camera relative to the subject. The orientation determination section provides an orientation signal recognizing either the vertical or the horizontal orientation of the camera relative to the subject. An image processor is responsive to the orientation signal for processing the image signal and correcting the orientation thereof so that the still image is output from the image processor in a predetermined orientation. In this way, the electronic still camera can be positioned in a variety of orientations relative to a subject, including both clockwise and counterclockwise vertical "portrait" orientations and a horizontal "landscape" orientation, without affecting the orientation of the images output by the camera.

摘要： A flash quench controller for a camera having a flash unit includes a light detector for producing a signal, an integrator for integrating the signal from the detector and producing an integrated signal, a comparator for comparing the integrated signal to a reference value, and means for quenching the flash unit when the integrated signal reaches the reference value. By using a pulse signal having a variable pulse width to programmably set the reference value, many different quench time values can be easily established. The flash unit may also be quenched by setting a maximum flash time value. The flash is automatically quenched if this flash time value is reached before the integrated signal level reaches the programmed reference value.

摘要： There is provided a display device in which disadvantageous effects due to unnecessary operations of an image lag alleviating function are minimized. In a display device of active matrix type, for each of the pixels arranged in a matrix, a current-driven emissive element is provided, and the current of the emissive element is controlled using a drive TFT so as to perform display. While a black display period during which an opposite bias voltage is applied between the gate electrode and the source electrode of the drive TFT is inserted in order to alleviate image lag, this insertion is performed only when a predetermined condition is satisfied, and is performed for a certain duration according to a command by a microcomputer (10).
