In 2014, high-end cameras will be popular with high-pixel, large-pixel, large-aperture lenses, closed-loop motors, optical image stabilization, dual-color temperature LEDs, and MFM flashes.
Trend 1: High pixels and high resolution enhance the details of the camera
Samsung is taking the traditional way of thinking. Looking at the model configuration of the Galaxy S series for 5 consecutive years, the gradual upgrade from 5M to 16M is obviously a high pixel route.
The higher the pixel, the more direct improvement is the resolution, and more details can be obtained by taking pictures. However, higher pixels will also increase the heat generation of the camera module, reduce noise suppression, increase the speed of the back-end platform, and increase the burden of image processing.
In 2013, Sony has launched a 21-megapixel mobile phone, while Nokia has launched a 41-megapixel mobile phone, no one has surpassed so far. In 2014, most companies will continue to adopt the idea of ​​pixel improvement. The high-pixel chips available for the Chinese market include 16-megapixel OV16825 and OV16850, Samsung S5K2P8; 18-megapixel Micron AR1820, 20-megapixel Sony IMX220 and IMX230 Wait.
Trend 2: Big pixels improve night shots and video recording
Apple is taking a different route. The number of pixels remains the same, and the size of a single pixel increases. HTC launched the industry's largest single pixel size of 2um to date in 2013.
As the size of a single pixel increases, the light energy acquired by a pixel in a unit of time increases, and the overall sensitivity of the chip is better. Noise suppression has been improved in daily photography, performance in low-light environments has been improved, and screen brightness has been significantly improved during video recording.
In 2014, Apple, HTC and other customers will take the large pixel route. There are not many chips available for the Chinese market. There are 4 million pixels of STD single pixel 2um VD6869, OVT single pixel 2um OV4682 and OV4688; 13 million pixels 1.34 OV13860 for um; OV16825 for 16-megapixel OVT single pixel 1.34um and so on.
Trend three, large aperture lenses increase the amount of light entering
Apple and Samsung all adopt large aperture lenses. In 2013, some models have been equipped with F1.8 aperture lenses. In 2014, F2.0 will gradually be popularized.
The advantage of a large aperture is to increase the amount of light entering the lens, improve the light energy obtained by a single pixel, and can better suppress noise in daily photography, while improving the shooting effect in low light environments.
Trend 4. Closed-loop motor improves focusing accuracy and focusing speed
The biggest feature of closed-loop motors and traditional motors is the addition of Hall and lens center design. Hall can detect the position of the lens, which can ensure that the lens runs to the ideal position and improve the focusing accuracy. At the same time, the design of the center of the lens combined with the Hall and the back-end algorithm can effectively increase the focusing speed and achieve the extremely fast focusing experience.
Closed-loop motors are currently available from Korea Magnetization and Taiwan TDK, with fewer models, slightly higher cost, and tight supply. With the entry of APLS and other manufacturers in 2014, the products will be more abundant, the supply will tend to be stable, and the cost is expected to decrease. Moreover, camera module manufacturers have more than a year of packaging manufacturing experience. The module production yield is expected to increase significantly, and the supply will stabilize.
Closed-loop motors are widely used on Samsung Galaxy S series and vivo X series models. Samsung even optimizes to 0.3 seconds for fast focusing, which is an extraordinary experience. However, many people in the industry believe that the closed-loop motor is a transitional product, which may be short-lived. However, in terms of product characteristics, resource conditions, experience and standards, and supply stability, closed-loop motors were still the ideal configuration for high-end models in 2014.
Trend V. Optical image stabilization improves image stability
Optical image stabilization is a key step for smartphones to move into card digital cameras, which can effectively solve the machine shake when taking photos after focusing, the hand shake during long exposure during night shots, and the shake caused by holding the human body for a long time during video recording. The image is blurred. Allow consumers to take stable and clear photos in a variety of environments.
The core component of optical image stabilization is the OIS motor. The effect is realized by the OIS algorithm. The supply of elasticity depends on the equipment investment and experience accumulation of the module factory. Optical anti-shake products are relatively complex, and how to integrate the resources of light, machine and electricity is the key.
There are rumors in the industry that Apple will release a new generation of flagship models equipped with optical image stabilization cameras in Q3. It is believed that more manufacturers' flagship models will be equipped with this configuration to grab market technical highlights and overall selling points.
Trend six, flash upgrade to enhance the color reproduction of night shots
The flash is a good partner for the camera. In 2013, Apple replaced the dual color temperature LED, which effectively improved the image color reproduction ability in the night shooting environment. Samsung changed the MFM flash module to effectively improve the luminous efficiency and uniformity of the flash. At the same time, the optimization of color reproduction was added to the next-generation MFM flash module to further enhance the night shooting effect.
From the exposure data, the upcoming HTC M8 will also use dual color temperature LEDs to enhance the night shot effect. Good horse with a good saddle, dual-color temperature LED and MFM flash module is expected to become the supporting role of the flagship camera phone.
