Buying Guide: Digital camera buying seven indicators – digital camera, buy – HC Network Appliance In by hi joiney

Consumers of DV Process must address the following issues into account, it is necessary to the pursuit of perfect function and also taking into account the requirements of portable, we must care about the price, but also according to their actual use to select the right product. At the same time, do not overlook Digital Camera Peripheral products, since they will directly affect the machine’s use. Pixel resolution Generally, the grades are based on consumer DV pixel resolution to the level of calibration, the high quality pixel resolution does not mean more good shot, because the shooting a DV image quality depends not only Sensor (CCD), and also the quality of the lens used, with the focus system, the use of anti-shake function, and so forth are closely linked. CCD digital camera is undoubtedly the core of the device, largely determines the shooting is good or bad. Can be said that the grade compact DV, mainly by the CCD pixel size and the decision to target the higher the better, of course, but the machine will follow the price rise. Generally, 1 / 6 inch, 800,000 pixels or more products have to meet the requirements of the ordinary household. Lens focal length and aperture To the fullest possible use of CCD pixels to capture images as clear as possible of natural, good camera manufacturer uses high quality optical lens, such as Sony DV Zeiss lens, the Leica lens Panasonic DV. In addition to Brand , The lens parameters should primarily focus on two indicators: the optical zoom range and maximum aperture. Limited size, compact DV camera on and not too many choices, these two indicators are basically 10 times and F1.8. As for the “digital zoom” is basically a digital Game , Little practical value, not too much concern. Still image capture capability Have the ability to DV still image capture can be used as a low-end Digital Cameras Use, although the majority of products currently on the market with this feature, but some are equipped with memory card, while others can only use MiniDV tape as storage media like. DV although the latter have the still image shooting capabilities, but still images are stored in the MiniDV as the band, generally not very high quality. DV uses memory cards are obvious advantages in this respect, still image resolution is often higher than the DV format with a lot of storage. Sony and Samsung use the memory stick save, and Panasonic, Canon, JVC will use the SD (MMC) card storage. DV still image shooting mainly by the CCD pixel size and the decision must also choose models with progressive scan capabilities, or vertical pixels will be halved. Viewfinder size and type Digital camera can be Liquid crystal Screen and the EVF (electronic viewfinder) two ways of framing, general compact DV limited size, most of its LCD screen size 2.5 inches, not choice, we mainly pay attention to their rotation, the number of pixels and the environment in the sunlight display. On the EVF we should pay attention to its color or black and white pixels, and whether the number of adjustable angles. Body appearance and weight Choose compact DV friend of course very concerned about the volume and weight of products. For the ordinary DV tape, vertical body design of the product, it should be said that the size and weight no big difference, but the specific shapes and colors, or different materials, etc., this should be the “carrot cabbage, the be loved, “the. Other aspects, we should also pay attention to battery capacity, the number of attachments, whether they have a 16:9 shooting mode, night shot mode. Also present with the use of non-compact MiniDV DV, DV with the absence of restrictions on the volume and weight greatly reduced. Control design When you pick a time when the digital camera to take note of the operation of various control methods are easy to use, and then try them again how these controls. For example, the body of the buttons and tags are easy to understand control, to see whether the human menu, often these details will be your choice on the machine for the key. About 4,000 yuan with the operation of the majority of DV are convenient buttons, and some had even adopted the LCD touch screen design, various menus can through the user’s “pointing” easy to open, convenient easy to use, it also omitted a lot of physical buttons, making DV the body becomes more simple and neat. From your computer Compact DV as small size, some manufacturers will omit a number of interfaces. This we should pay attention, be sure to select interfaces as complete products. Such as IEEE1394, USB, analog video, audio input / output terminals, MIC interface is indispensable. Some compact DV omitted analog input jack, and some use non-standard size interface, which will affect our daily use, we pay attention to the time of purchase.
