This site shows the new line-up of Panasonic projectors and provides
detailed information for home use and business use projectors.
This intelligent iris system works by analyzing the brightness level of each image using a histogram, then adjusting the lamp power, iris and gamma curve* accordingly to create the ideal image. The adjustments are made virtually frame by frame. This achieves an astounding contrast ratio of 50,000:1, providing a wide dynamic range with swift smoothness for added beauty in both dark and bright scenes.
* Parameters for adjusting the output brightness gradation level according to the input signal.
The optical filter optimizes the light spectrum from the UHM projector lamp, helping to produce deeper blacks while improving purity levels in the three primary colors (red, green and blue). This advanced filter system improves color purity to cover a range that extends from the HDTV standard (Rec. 709 mode)*1 to the color gamut used in digital cinema.*2 This gives images the deep, rich coloring that distinguishes movie images.
*1 A setting that supports the 6,500K color temperature recommended in the HDTV standard (ITU-R BT.709)
*2 Specifications put forth by the Society of Motion Picture and Television Engineers (SMPTE) DC28 Digital Cinema committees.
This digital image processing circuit brings greater clarity and sharpness to details, even in fast-moving scenes.
The resulting images have a more natural, lifelike expression.
When the output level of the source device fluctuates due to the performance of the device or its cable connections, the original black and white levels of the image content cannot be reproduced. With the PT-AR100/AH1000, you can view the waveforms on the screen and adjust the settings either automatically or manually as you prefer.
You can freeze any scene you wish, and then make adjustments while easily comparing the original image and the adjusted image side-by-side.
The gamma curve can be flexibly controlled, allowing precise calibration according to the signal source and environment. Brightness (Y), R, G and B can each be adjusted at any of nine points. Adjustment point positions can be shifted both horizontally and vertically to bring out the desired gradation level.
This color correction system enables free color control in two different modes. The Point Color Correction mode lets you pick a point in the image and adjust that color without affecting the neighboring colors. The Six Color Correction mode enables independent adjustment of red, green, blue, cyan, magenta and yellow.
