互联网的日益普及和广泛应用,令“摄像头”也大行其道,家庭购买摄像头有以下几大窍门: 1.购买摄像头最主要是看摄像头所显示的影像片段是否有停滞现象。如果把摄像头的画面调至较高解像度,会有停滞的情况。正因为如此,“聪明”的商家会预先把显示器的解像度调低,令摄像头的画面相对放大,消费者便容易产生错觉。例如原本显示器的解像度为1024×768,摄像头为320×240,如将显示器的解像度调低至800×600,便容易误以为摄像头的解像度提高了,所以用户购买时要注意。2.重点审视摄像头的图像颜色与亮暗等。如是否偏色、太亮或太暗,用户都应注意。
The growing popularity and widespread use of the Internet have made the “webcam” popular. There are several tips for families to buy a webcam: 1. The most important thing about buying a webcam is to see if there is any stalling of the webcam displayed by the webcam. If the camera’s screen to a higher resolution, there will be stagnation. Because of this, “clever” merchants will advance the monitor’s resolution down, so that the camera’s screen is relatively enlarged, consumers are prone to illusion. For example, the resolution of the original monitor is 1024 × 768 and the camera is 320 × 240. If the resolution of the monitor is reduced to 800 × 600, it is easy to mistakenly think that the resolution of the camera is improved, so users should pay attention when purchasing it. 2. Focus on the camera’s image color and light and dark look. Such as whether color cast, too bright or too dark, the user should pay attention.
