MediaTek Helio P90, dual ARM Cortex-A75, six ARM Cortex-A55

Posted by Charbax – March 6, 2019

MediaTek Helio P90 dual ARM Cortex-A75 with 6 ARM Cortex-A55 in an octa-core cluster, with powerful AI APU 2.0 with 1165GMACs performance, Imagination PowerVR GM 9446 GPU, LPDDR4X memory, supports up to 48MP camera sensors (44.7% larger than 8K), 48MP at up to 30FPS with zero delay (ZSD) or 480FPS in 16MP. Dual camera arrays of up to 24+16MP can do 30fps bokeh live-previews that are 6X faster and 2.25X higher resolution than competitor claims MediaTek. Upgraded triple ISP that’s now capable of 14-bit RAW and 10-bit YUV processing. CorePilot control that supports ACAO (all cores all open), AI-enhanced low-light noise reduction algorithm is 4X faster and is also the first ever AI-feature in CV (computer vision) performance.

Cheaper Pico 4K Projectors are coming, powered by TI DLP470TP

Posted by Charbax – February 23, 2019

Texas Instruments presents their latest DLP470TP projector chipset that enables cheaper and more compact 4K Projectors, using LED and Laser light sources, this enables 4K Pico Projectors, 4K Portable Projectors like the Optoma UHL55 which I filmed here more affordable Ultra Short Throw 4K projectors are possible too like the ones from Jmgo which I filmed here Most Cinema projectors use DLP, and Texas Instruments here have even further reduced the size, power consumption and price of their 4K Projector solution, their DLP660TE enables projectors up to 5000 lumens, DLP470TE for projectors needing over 1500 lumens while the new DLP470TP goes in projectors that use below 1500 lumens, thus making portable pico 4K Projectors now possible. In this video, TI also shows some of the newest on-table smart interactive projectors such as the Puppy Cube and the Bosch projector PAI, then also TI shows the new concept of the Smart Speaker Short Throw Pico Projector such as the Humax Vision, a new segment to be integrated with Alexa or Google Assistant and projecting onto a nearby wall all the smart speaker information displayed. In this video TI also shows the personal assistant looking like a holographic 3D image floating in space.

Nanosys Quantum Dots HDR color vs OLED, Speed demo vs KSF phosphor

Posted by Charbax – February 23, 2019

Nanosys shows Vizio P Quantum, with 2,400 nits of peak luminance and full DCI-P3 coverage compared with LG's latest OLED display for using with UltraHD 4K HDR content. Nanosys uses AJA Video Systems’ HDR Analyzer tool that uses color science from Color Front to analyze the luminance and color chromaticity of every pixel in a piece of content real time. Looking at BT.2020 HDR10 content graded at 4,000 nits they are able to observe how the two different TV technologies respond.

Quantum Dots deliver the widest color gamut and highest peak luminance for a lifelike HDR content experience, they are also the fastest wide gamut technology. Nanosys shows a wide color gamut speed shootout comparing the response time of Quantum Dots to KSF phosphor, a competing wide color gamut technology. Quantum dots can be switched on and off in a matter of nanoseconds while KSF phosphor takes milliseconds to respond. While milliseconds sounds pretty fast, it isn’t fast enough for Full Array Local Dimming (FALD) displays when it comes to high frame rate content. Quantum Dots respond in perfect synch with the signal for clear motion and near-perfect black levels. In KSF displays, the red component needs time to warm up and cool down over several milliseconds. In the soccer ball example below this slow response time causes a cyan leading edge and a red trailing edge as the ball moves across LED zones on the display.
