4k e-shift2 is an exclusive JVC technology that allows us to produce projectors with 4 times the resolution while utilizing much of our existing infrastructure, keeping the projectors small and affordable.
For 2013, we've made significant upgrades to the original e-Shift-now called e-shift2-which include an all-new optical device, smarter Multiple Pixel Control technology, and improved enhancement & upscaling. All of this results in a picture with significantly improved contrast, and more natural color tones than on previous models.
With the previous version of e-shift, the original 1920 x 1080 signal was processed using a correlation detection algorithm to uncover detail that could be enhanced on a 4K display. With e-shift2, a much wider area is sampled-12 times as many pixels than previously-which results in improved edge transitions, zero aliasing and stair-stepping, and a significant increase in contrast in detailed areas. New sub pixels are generated based on this detection and a 3840 x 2160 frame is created and enhanced. Our new 8 band analysis filter delivers much more accurate smoothing and enhancement than the previous 2 band filter. The enhanced 4K frame is then temporally separated into subframes 1920 x 1080 pixels each and projected using a the D-ILA optical system through the e-Shift2 device. The original e-Shift device used liquid crystals to shift the subframes by 0.5 pixel both vertically and horizontally. Our new e-shift2 device shifts the image without the use of liquid crystals, resulting in better overall resolution linearity and ANSI contrast. This creates an image with 4 times the pixel density of the original content.
