How to choose a digital camera? Digital camera purchase points

With the continuous development of the digital camera market, the functions of new products are becoming more and more powerful. Faced with various digital cameras and various technical parameters, some users who do not understand the market will inevitably be confused. So how do you buy a digital video camera ? The following decoration home decoration network Xiaobian will bring you the digital camera purchase points for your reference.

How to choose a digital camera?

Digital camera purchase points 1, price factors

When buying a digital video camera, there will be a budget price in mind, and if it exceeds the psychological price, we may choose to give up buying this type of camera. When buying a camera, be careful not to pursue high prices when positioning prices.

High price will generally improve performance, just pay attention to some performance is not suitable for you, some just improve the quality of photo shooting, such as SONY TRV16E and TRV18E difference of 750 yuan, but the difference is mainly the latter than the former still image shooting The ability is stronger, generally there is no need to buy the latter, you can completely save your money, and does not affect the performance you require.

Digital camera purchase points 2, CCD pixels

Although the CCD pixel basically determines the grade of the digital camera, the high pixel does not mean that the shooting quality is definitely better, and the pixel is not as high as possible. This is because the quality of the digital camera is not only dependent on the CCD, but also closely related to the quality of the lens used, the focus system equipped, and the anti-shake function used.

Secondly, some functions of the digital video camera also need to be sacrificed by some pixels. For example, a digital video camera using anti-shake technology needs to sacrifice some pixels to realize the anti-shake function. Therefore, the actual effective pixels of the general CCD tend to be larger than the nominal value. It is much lower, for example, the nominal value of 800,000 is only about 400,000 RMS.

Digital camera purchase points 3, lens zoom

Zoom is divided into optical zoom and digital zoom. In fact, optical zoom performance and digital zoom performance are not related, but many manufacturers will use the multiple of digital zoom as a selling point. In fact, digital zoom is only generated by magnifying the captured image and then scientifically filling the blank part. It is called interpolation method. The more interpolation components, the more details of the sacrificed picture, the lower the definition, the meaning is meaningless. .

Therefore, the multiple of digital zoom is basically not included in the scope of consideration. Don't listen to the irresponsible propaganda of the merchants. I mistakenly believe that the digital zoom function can compensate for the lack of optical zoom range. Friends who use digital cameras know that this function is basically It's just a number game.

Digital camera purchase points 4, anti-shake function

At present, digital camera and digital camera manufacturers have basically increased their efforts to develop the function of mitigating the effects of jitter. This function is especially important for digital cameras that need to be handheld and moving in most cases. It is regarded as a measure of the pros and cons of a digital video camera. An important indicator. The anti-shake function is the same as the zoom function. There are also optical and digital points. There are great differences between the two, and most digital cameras only provide digital anti-shake function.

Digital anti-shake is to use the remaining area and pixels on the CCD to compensate the image afterwards. In addition to the poor effect, the shutter speed is also affected to a certain extent when the digital anti-shake function is turned on. The light is not very good. The next will affect the quality of imaging, the advantage is that the cost is relatively low, so the price of the camera that provides digital anti-shake function is also relatively low.

The optical anti-shake function is directly realized by an imaging device such as a lens. According to the direction and degree of the camera's shaking, the position and angle of the lens are adjusted, and the position or angle of the imaging device is changed to keep the imaging stable. The effect is better than the digital image stabilization. Excellent dynamic function is an important indicator to measure whether a digital camera is upscale.
