Famous for its high cost performance, the millet 3 camera's performance does not let a person ecstasy, and industry compared to high-end products, its image performance in one color distribution consistency (local partial color problem) is slightly inferior.
Results analysis
Photo color deviation of the mean square value: red mean square deviation value is 0.87%, the deflection.
Photograph trichromatic pixel brightness distribution one to sex: red change obviously.
Overall evaluation: although millet 3 brand high-end low price, but the performance of the camera is not how to let a person ecstasy, photos of a slightly off color, local biased color phenomenon.

Mobile phone camera 3 meter series of millet
Test case
When buying a mobile phone, found that camera indicators are marked with only 8 million, 13 million pixels, does it feel like you do not know how to start?
Camera indicators in addition to the brand, pixel resolution, you know the sensor size, lens, and the effects of number of pictures?
Do you know how to use the photo color deviation of the mean square value and brightness distribution one sex to determine the color difference between partial and photos?
Unknown sleep Shirley? Swollen yao?
Hardware testing expert close Jian blockbuster launch mobile phone camera assessment big time!
This evaluation is not only bring you up "posture" feeling, is not only a handsome boy, sister of capital, but also not be to you a mobile phone manufacturer fool "strongest mind".
On the aroma one cup of coffee, is jin sits, open the computer, one admiring prick silk 3 favorite - millet mobile phone camera the authority of the evaluation.
Review began

 

Above were taken in natural light with millet 3 printing photos with A4 paper.
Photo color brightness distribution consistency evaluation
Basic cannot judge the quality of camera with the naked eye closed Jian the value of the three primary colors with tool extracted respectively, divided into 32 x18 a square pixel averaging, and do analysis of the distribution of brightness.
Here are red, green, blue three primary colors surface brightness distribution, said by color (red high brightness, low light green said)

Millet 3 photos of three colors (red, green and blue) pixel luminance distribution
Below is the iPhone 5 s photo three colors (red, green and blue) pixel brightness distribution:

IPhone 5 s photo three colors (red, green and blue) pixel luminance distribution
In theory, red, green and blue color in the picture the brightness distribution, the more one to show that the quality of the photos, the better. The look from the figure, the color distribution is slightly difference, especially the red changes significantly, and set the gap between the iPhone 5 s. Image brightness distribution on the surface there are ups and downs of the external environment is likely to be taken when the (shooting conditions) effect, is often not the camera itself. But pure white object, not one of the three primary colors distribution in words, it is at least one part is the camera itself. It said it's not a big problem, but in extreme conditions may be some local area on the image of the partial color, color is not uniform, so as to reduce the image quality.
Photo three primary colors mean square deviation value evaluation
With color brightness of average for reference, take out the influence of the overall brightness deviation.
The following three figure is an average color brightness and brightness deviation chart

The average brightness and brightness deviation chart
The figure can be seen, with millet 3 photographs in the red part (left) the upper relatively bright and surrounding slants dark; Green part (center) a central circular relatively dark area; On the blue part (right), silenced present complementary and the red part. Preliminary view, the three primary colors of slightly different brightness distribution, which may have influence on the stability of the photo color, lead to regional slightly off color.
To quantitatively analyze the effect of chromatic aberration, we calculate color brightness than the ratio of average standard variance and brightness:
Red: 0.87%
Green: 0.53%
Blue: 0.56%
But from the numerical, maybe can't see pictures quality, we are in the same condition the iPhone 5 s photograph comparing the mean square deviation value:
IPhone 5 s camera photo mean square deviation value:
Red: 0.524%
Green: 0.276%
Blue: 0.532%
In theory, the mean square deviation value as small as possible. Data from two groups of contrast, millet 3 cameras photographed the mean square deviation value compared to the iPhone has set the gap 5 s, red exceeds 0.35%, while green also is larger than the iPhone 5 s by almost 0.3%. This suggests that with millet 3 photographs will be a slight color difference phenomenon.
conclusion

Millet 3 mobile phone cameras
Millet 3 cameras for SONY 13 million pixels IMAX135, F2.2 aperture, 28 mm super wide Angle, 5 pieces of specialized lenses, blue glass infrared filter. The hard Numbers, millet 3 cameras compared with other mobile phone, belongs to the average level. And from a professional point of view, the comparison in one color brightness distribution to sex and mean square deviation value analysis can be seen, millet 3 photographs will be slightly off color, and local also have partial color phenomenon.
Millet 3 camera parameters:
The sensor Samsung/OV back according to type
8 million pixels
Sensor sensitive area of 1.4 mu m
Lens 5 special lens, infrared filter blue glass
Aperture F2.2
Flash/LED flash as the fill light
features Equipped with a digital image stabilization (DIS), can undertake HDR, panoramic camera
