[IT168 News] On December 1, 2016, MediaTek today announced the addition of a new member to its high-end MediaTek Helio X20 series, launching two new upgraded smart phone system SoCs - MediaTek Both the X23 and X27 have significantly upgraded in terms of overall performance, shooting quality and low power consumption, once again elevating the user experience to a whole new level. Through the improved layout of MediaTek Technology's X20, X23, X25 and X27, positioning the high-end Mediatek Xeon X20 series will assist handset manufacturers to introduce more differentiated smart terminals.
MediaTek said that during the first half of this year, MediaTek has announced the concept of “core normal†when it released the X20 and X25, which means that the high-end chips from MediaTek will meet the needs of manufacturers and consumers by improving the user experience. And personalized needs. In line with this concept, MediaTek launched an upgraded version of the X23 and X27, which not only optimizes the dual-camera function to a first-class level, but also achieves the best performance in terms of balance of performance and power consumption among its peers, and further strengthens the Mediatek Technology brand. The competitive advantage. â€
Better frequency upgrade performance
MediaTek Technologies X23 and X27 use a ten-core three-cluster architecture (2x ARM Cortex-A72 + 4x ARM Cortex-A53 + 4x ARM Cortex-A53) and CorePilot 3.0 heterogeneous computing technology through precise task scheduling and core assignments. At the same time taking into account the processor performance and power consumption. In comparison with the highest-end Xeon X25, the new Xeon X27 will increase the large-core clock frequency to 2.6GHz, and the GPU clock frequency will be upgraded to 875MHz. The CPU/GPU co-scheduling software and algorithm will be further optimized. The overall performance increased by more than 20%, and both the web browsing experience and the application (APP) startup speed were significantly improved.
ImagiqTM upgrade to take more powerful pictures
MediaTek Technology X23 and X27 are equipped with an upgraded ImagiqTM Image Signal Processor (ISP), which not only enhances the Dual PD (Full Pixel) dual focus function, but also integrates the Color (Mono) and Mono (Brightness) smart devices for the first time in the industry. Photographing and real-time shallow depth of field photography and video functions to achieve a quality and function shooting experience. The upgraded version of ImagiqTM has been significantly improved in terms of picture clarity, saturation, exposure control, character performance, and large aperture effects, bringing a richer “lens†life to smartphone users.
Power Saver Technology Enables Lower Power Consumption
Mediatek Technology X23 and X27 equipped with envelope tracking module (Envelope Tracking Module), according to the strength of the output signal of the power amplifier, dynamically adjust the output supply voltage, making the power amplifier significantly improve efficiency, and reduce the radio frequency power consumption and hair Heat, saving about 15% of power at maximum output power.
In addition, the use of MiraVisionTM EnergySmart Screen power-saving technology can intelligently and dynamically adjust the screen system parameters according to different display contents and ambient brightness, and with the human-eye visual model technology, it can ensure non-destructive visual enjoyment, and can reduce up to 25% Screen power consumption.
The double-concave lens is similar to the plano-concave lens. The focal length is negative, but the parallel incident light diverges outward. The two side surfaces of the double-concave lens have the same radius of curvature, and are generally used for beam expansion and projection.
The image formed by the biconcave lens is always smaller than the upright virtual image of the object. The biconcave lens is mainly used to correct myopia. Myopia is mainly due to the deformation of the lens, which causes the light to gather in front of the retina prematurely. The double-concave lens plays a role of diverging light. The double-concave lens becomes an upright, reduced virtual image, which makes the image distance longer and just falls on the retina.
