Abstract: In an image displaying field where there is a tendency which will increase the data to be handled in accordance with the high integration of a display device, a CRT controller according to the present invention improves the superposed display and the responsiveness of the display and drawing operations by dividing a unit clock into a predetermined number to function with high speed and a multifunction display. When image data are to be inputted or outputted from a refresh memory corresponding to a display frame, the memory content and the display address are assigned at a ratio of 1:n to effect the processings in parallel. As a result, the time period utilized by the display cycle of the prior art can be assigned to the drawing operation so that the processing can be speeded up while making it easier than the prior art to effect the superposed display of letters, symbols and drawings.

Abstract: A manual interface combines continuous and discrete control and display capabilities. The manual interface can be embodied by combining a haptic interface providing continuous control and display capabilities with one or more of multiple discrete selectors (such as tagged objects) providing discrete control capabilities.

Further, unlike a conventional haptic interface device, the manual interface can provide easily selectable, multiple interactive possibilities.

Abstract: The invention provides a data display device and a system which display a sales amount or number of coins inserted into, for example, a game machine in a form not directly comprehensible to a person in order to prevent reading by an unauthorized person. This prevents dishonest acts or pilfering by the unauthorized person. This form, not directly comprehensible, can be a bar code. The unauthorized person can read the sales data only by a bar code reader, so he will have no way to know the sales amount to match with the actual collected amount of the coins.

Abstract: A method of operating a liquid crystal cell includes DC-balancing by displaying an inverse image with electric fields of increased magnitude relative to the image producing electric fields. While the inverse image is displayed the image is prevented from being visible by either turning off the light source or re-directing or blocking the light from reaching the viewing area. The image producing electric fields and the inverse image producing electric fields are such that the cumulative time integral of the electric fields that are present in one direction across the liquid crystal material is substantially equal to the cumulative time integral of the electric fields that are present in the opposite direction during the given period of time during the operation of liquid crystal cell. The time duration of the inverse image portion is shorter than the time duration of the image portion by an amount proportional to the increased magnitude of the additional electric fields.

Abstract: A halftone display method utilizes an activation sequence, having a plurality of luminance blocks predefined in each frame or field to display an image and having redundancy, that enables one gray-scale level to be expressed by any one of a plurality of combinations of subframes (luminance blocks). When determining luminance blocks for use to display gray scale of an arbitrary first pixel, the luminance blocks to be used for the first pixel are selected in accordance with a predetermined rule, based on how the luminance blocks are used for a second pixel located in close proximity to the first pixel. In this way, by actively utilizing the redundancy of the activation sequence, the occurrence of moving-image false contours (false color contours) in video can be minimized, and also a motion compensation equalizing pulse method can be effectively applied to further improve the image display quality.
