meilleur smartphone photos comparatif iphone vs android

The earliest Android smartphone was the 2008 release of the Android G1. " A Short History of the Future: Legends of the Intelligent Era " was equally exciting. Everyone was welcome to click and read it!

The advantages of smartphone photography are as follows: 1. ** Lighter **: Overcomes the inconvenience of carrying the camera. DSLR cameras and lenses were heavy. Unless they were specially used to take photos, people would not carry them around at all times. However, mobile phones had become people's personal belongings, making it easy to record wonderful moments at any time. 2. ** Intelligent **: Overcomes the drawbacks of the camera's complicated operation. DSLR cameras needed to adjust the aperture, speed, white balance, and other parameters to shoot (using smart mode would lose the meaning of DSLR), while mobile phones did not need such complicated operations. Some mobile phones had artificial intelligence vision, which could automatically identify the scene and adjust the parameters. The user could focus more on light and shadow, composition, and the subject. Of course, the phone also had a professional mode to adjust the camera parameters. 3. ** Visualization **: Overcome the limitation of camera viewing. DSLR cameras generally used the viewfinder to view, which was inconvenient to operate when shooting at low angles. However, mobile phones could be used to take pictures from multiple angles, such as turning the phone upside down to shoot at low angles, using the selfie stick to shoot from above, and could also be used for selfies. 4. ** Integration **: Overcome the problem of the camera not being able to post-process. DSLR cameras could not be processed on the body. They needed to be imported into the computer before sharing. After shooting on the phone, they could immediately perform post-processing on the phone. The phone came with a powerful editing function and could also use the photo editing APP to perform partial processing. The operation was simple and intuitive. 5. ** Real-time **: Overcome the lag of camera sharing. After shooting with a mobile phone, post-processing could be carried out immediately and shared quickly on Social networks. After shooting with a single-lens reflex camera, it had to be imported into a computer for processing before sharing, which was less time-efficient. There were also the following disadvantages to taking photos with a smartphone: 1. ** Image quality needs to be improved **: The size of the mobile phone determines that it cannot use a larger sensor than a single-lens reflex camera, nor can it have a rich optical lens group like a single-lens reflex camera. Its image quality mainly depends on the algorithm to improve, and it is difficult to achieve the best image quality of digital cameras of the same period. It is difficult to enter the professional photography field. 2. ** Shutter response lag **: DSLR cameras use a mechanical shutter, and you can shoot immediately when you press it. On the other hand, mobile phones use an electronic shutter, and there will be an obvious lag when shooting moving objects, which is not conducive to capturing photos and makes it easy to miss important pictures. 3. ** hardware limitation **: Most smart phones have a narrow field of view after equivalent focal length conversion. Although there are multi-camera lenses, there is still a gap between imaging and optical lenses. The adjustment of lens parameters is limited and the imaging is poor. 4. ** Poor Foreground Bokeh Effect **: Although the mobile phone can shoot the background bokeh effect, the Foreground Bokeh effect is not good. It either doesn't exist or isn't natural enough. Although there is an APP that can simulate it, it still can't compare to the depth of field effect of an optical lens. When shooting portraits or flowers, the DSLR camera has an advantage. 5. ** Weak optical zooming ability **: Most mobile phones use digital zooming, which is a loss zooming. The quality of the image will be reduced when zooming to shoot distant scenes. The optical zooming of the lens of the single-lens reflex camera is a loss zooming, which can guarantee the quality of the image even when shooting distant scenes such as the moon. 6. ** Depth of field compression effect is not good **: Some phones have poor depth of field compression effect, which is related to the sensor and lens of the phone. It is not as good as optical telephoto lens when shooting close-up scenes. 7. ** Small size of the sensor **: The high resolution of the phone does not mean that the image quality is good because the size of the sensor is small. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

If an Android phone flashes when taking a photo, there may be the following reasons: 1. When the anti-flash function was used together with the WVR, it was easy to cause a flash screen problem. The anti-flash function was generally used indoors to filter the ripple-shaped flicker produced by the light. If the anti-flash function of the equipment was always turned on, it might cause a flash screen. 2. If the gain and exposure time of the automatic exposure were not properly set, such as when the digital gain was written to 0, it might cause some slight flicker. 3. If the weight value of the region of interest was too high, the exposure strategy would be in the highlight priority mode. In order to prevent overexposed, the brightness value would be appropriately reduced. When the AE algorithm found that the brightness of the image was smaller than the target brightness, the brightness value would be increased again. This increase and decrease would cause flicker. 4. For some sensors, when the automatic exposure adjustment speed (u8Speed) is greater than 64, the image may flicker. 5. The exposure time and sensor gain do not meet the linear relationship. For example, when the exposure is 4096, the relationship between the distribution of exposure time and gain does not meet the requirements. The adjustment of the ADC may cause flicker, which can be solved by setting f32Offset. 6. If the system's gain allocation is unreasonable, it may also cause flicker. For example, if the sensor's digital gain, sensor's digital gain, and ISP's digital gain are not reasonably limited, it is easy to cause flicker. If you encounter a flash screen problem, you can try the following solutions: 1. Remove the anti-flash function (because the anti-flash function will cause the screen to flash when used with the WVR). 2. Added digital gain adjustment (check if there is only again adjustment but no dgain in the code. It has been verified that dgain will also affect flicker). 3. He adjusted the weight of the region of interest. 4. Adjusts the brightness of the target (for example, from 65 to 128). In addition, past usage errors could also affect: 1. The exposure strategy, high light priority, low light priority, was used wrongly. 2. The exposure deviation value is not set properly (if the value is too low indoors, the image is too dark). 3. The digital gain of the sensor was not adjusted. 4. The anti-flash treatment was always on. 5. The weight value of the region of interest (indoor and outdoor) was too high, causing the brightness of the outdoor mode to not be increased, and the screen was too dark. 6. The area of interest had a great influence on the average statistics, so the brightness of the outdoor mode could not be increased, and the screen was too dark. At the same time, there might be problems with the camera itself, such as screen brightness optimization. Whether it was indoor or outdoor, the brightness of the camera was low. Although it could be solved by turning on WDr, it would bring about problems such as increasing the bit rate and increasing noise. The reasons for the low brightness of the image included that the exposure strategy in outdoor mode used highlight priority and the weight value of the region of interest was too high, so the image brightness could not be improved due to being too sensitive to highlights; the exposure strategy in indoor mode used low light priority, but the exposure deviation value (u16EVBias) was set too low, resulting in the final target brightness being particularly low, making the indoor mode image very dark. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The serious reflection of the iPhone camera can be solved by the following methods: - ** Cleaning **: If there are fingerprints, oil stains, and other dirt on the lens surface or phone screen that may cause light reflection, you can use a clean, soft cloth to gently wipe the lens surface, or use a special phone cleaning kit to clean it. - ** Light adjustment ** - ** adjust the angle of light or shooting position **: Change the angle of light or shooting position to prevent the light from shining directly on the surface of the lens. - ** Adjusting exposure **: The reflection may be due to the high exposure. You can adjust the settings as follows. He opened the phone's " settings-camera ", found the " mirror front camera "," retain settings ", and " exposure adjustment " buttons and opened them. Then, he opened the phone's camera, found the " small arrow at the top ", and clicked open it. Then, he clicked the " plus and minus buttons to adjust the exposure settings " at the bottom to reduce the exposure according to the actual situation. He could also enter the photo function in the phone's settings, check the original photo below, go back to the settings, click on the camera function, click on the format option on the page, and finally check the efficient option to solve the problem. - ** Using auxiliary items ** - ** Reflective Screen Protector **: Stick a layer of reflective screen protector on the screen to reduce the reflection problem. - ** filter **: Use a filter to reduce reflection problems during shooting. For example, use a polar filter to reduce mirror reflection. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
