C |
| Color Temperature |
| The coloration (reddish, white, bluish, greenish, etc.) of white in an image, measured using the Kelvin (degrees K) temperature scale. Higher temperatures output more light. |
| ColorMax™ (Digital Projection) |
The majority of Digital Projection's single-chip and 3-chip displays include a new standard in advanced color balancing: the DP-exclusive ColorMax™ calibration system. This advanced color calibration brings a new level of precision to all sizes of screen projection. Projectors configured with ColorMax™ are pre-aligned to a factory reference to assure consistent color performance straight out of the box. For more specific color alignment, the user has the ability to adjust color temperature, as well as the highlights and shadows of individual colors, on both a global and per source level. Given the depth of adjustment handles, ColorMax™ enabled projectors can be quickly benchmarked for color alignment and calibrated for color critical applications.
By providing the ability to manipulate primary and secondary colors as well as the white point, the user gains expanded control over the gamut of colors the projectors can display. By way of a simplifed setup procedure, an installer can simply measure and record the red, green and blue x and y color points and luminance values with a light meter and enter the values into a computer connected to the projector. ColorMax™ then analyzes the user input and a software algorithm automatically calibrates all of the color settings, per input, to produce a perfectly calibrated d6500 output. For cinema purists, this assures that the displayed content accurately reflects the artistic vision originally captured on the film. |
| Component Video |
| See YcbCr or YPbPr. |
| Composite Video |
| The output of video tape players and some computers, characterized by synchronization, luminance and color signals combined on one output cable. |
| Contrast (ratio) |
| The degree of difference between the lightest and darkest areas of the image. |
| Convergence |
| The alignment of the red, green, and blue elements of a projected image so that they appear as a single element. |
| Curved Screen |
| A projection screen which is slightly concave for improved screen gain. Curved screens usually have screen gains, which are greater than 1 but viewing angles much less than 180°. Curved screens are not recommended for use with this projector. |
D |
| DDC |
| The Display Data Channel VESA standard enables communication between PCs and monitors, and is based on E-EDID protocol. |
| DDI |
| A “direct digital interface” signal can be supplied to a Christie projector via an optional digital input module. For example, you can input an SMPTE- 259M signal using a Serial Digital Input Module or input an SMPTE-272M signal from a Digital HDTV Serial Input Module. |

| Detail |
| The sharpness of a display from a video source. |
| Diffused Screen |
| A type of rear-projection screen which spreads the light striking it. Screen gain is less than 1 but audience viewing angles are increased. |
| Digital Interpolation |
| Also known as digital scaling. The process of averaging pixel information when scaling (resizing) an image up or down. When reducing the size of an image, adjacent pixels are averaged to create fewer pixels. When increasing the size of an image, additional pixels are created by averaging together adjacent pixels in the original smaller image. |
| Display Setting |
| An adjustment that affects the display of an image. Such display settings include contrast, brightness, tint, blanking, size, offsets, and others. |
| DMD™ |
| Digital Micromirror Devices™ - a display device chip, in a DLP® projector, that is the core device of Texas Instruments' DLP technology. |
| Dot Clock |
| The maximum frequency of the pixel clock. Also known as pixel clock rate. |
E |
| E-EDID |
| The Enhanced Extended Display Identification Data standard, established by VESA, enables properties (such as resolution) of a display device to be detected by the display card in a controlling device such as a PC. The PC, in turn, can then output in a matching format to fill the display. Some sources used with the projector are VESA EEDID reported. |
F |
| Flicker |
| A very rapid variation in image brightness caused by a frame rate that is too slow. (See Interlace) See also Lamp Flicker. |
| Foot-candle |
| The intensity of visible light per square foot. |
| Foot-lambert |
The luminance (brightness), which results from one foot-candle of illumination falling on a perfectly diffuse surface.
