Photosensitive element CCD

Body-type household digital camera

The size of the photosensitive element is 1/2.5 inches.

Maximum number of pixels (10,000) The maximum number of pixels translated into Chinese is "charge coupled device", which, like the negative film of a traditional camera, is a circuit device that senses light. You can think of it as tiny sensing particles scattered behind an optical lens. When light and images are projected onto the CCD surface through the lens, the CCD will generate current and convert the sensed content into digital data for storage. The more CCD pixels, the larger the size of a single pixel, and the clearer the collected image. Therefore, although the number of CCD is not the only key to determine the image quality, we can still regard it as one of the important standards of camera grade. 830

Effective CCD pixel (ten thousand) 800

Maximum resolution (dpi) 3264×2448.

The image resolution (DPI) is 3264× 2448, and the widescreen is 3264× 1832, 2592× 1944, 2048× 1536,1600×1.

Optical zoom (multiple) Optical zoom (multiple) depends on the optical lens structure to achieve zoom. The zoom mode is similar to a 35mm camera, that is, the lens of the camera moves to enlarge and reduce the scene to be shot. The greater the optical zoom factor, the farther the scene is photographed. At present, the optical zoom magnification of digital cameras is mostly between 2 and 5 times, and the optical zoom effect of some code cameras reaches 10 times. The optical zoom factor of home camcorder is 10 ~22 times, and it can clearly shoot things 70 meters away. Using a magnifying glass can increase the optical zoom factor of the camera. four

Digital zoom (multiple) Digital zoom (multiple) is actually an electronic enlargement of a picture. Some pixels on the original CCD image sensor are enlarged by interpolation, and the pixels on the CCD image sensor are enlarged to the whole picture by interpolation algorithm. Through digital zoom, the shot scene will be enlarged, but its definition will be reduced to some extent, which is a bit like the zoom function in VCD or DVD, so the practical significance of digital zoom is not great. At present, the digital zoom of digital cameras is generally about 6 times, and the digital zoom of cameras is about 44 times to 600 times. In actual use, 40 times is enough. If the zoom factor is not enough, we can add a magnifying glass in front of the lens. If the shooting angle is small, you can increase the wide-angle lens accordingly. four

Lens performance Lens performance The lens of a digital camera consists of multiple lenses, and the materials are divided into two categories: glass and plastic. Some manufacturers emphasize that their camera lens is made of glass, so it has good transparency and the projected image is clearer. However, at present, many test reports show that glass lenses do not necessarily bring clearer images than plastic materials, and at the same time, glass lenses may increase the weight of the camera, so you should observe in many aspects when purchasing, and don't stick to the lens materials. F = 5.8-23.2mm.

Focus range 45 cm-infinity

Macro: 5-45cm (wide angle) and 30-45cm (telephoto).

Shutter shutter: A device that prevents light from reaching the front of the lens. Generally speaking, the longer the shutter time range, the better. Low seconds is suitable for shooting moving objects, so a camera emphasizes that the shutter can reach116000 seconds at the earliest, which can easily capture fast moving targets. However, when shooting traffic at night, the shutter time will be lengthened, and the silky water flow effect in ordinary photos can only be photographed with a slow shutter. As for the common B shutter function of monocular cameras, although you can freely decide the exposure time and have high shooting flexibility, most consumer digital cameras can't support it at present, and can provide the default values of slower speeds such as 2 seconds, 8 seconds, 16 seconds at most. Mechanical electronic shutter

Shutter speed (seconds) 15s- 1/2000s.

Equivalent sensitivity Equivalent sensitivity ISO sensitivity is a measure of the sensitivity of traditional camera negatives to light, which is usually expressed by ISO number. The larger the number, the stronger the optical rotation. Commonly used methods are ISO 100, 400, 1000, etc. Generally speaking, the higher the sensitivity, the coarser the particles of the negative film, and the worse the magnification effect, and the digital camera also uses this ISO value to mark the metering system. Automatic, high ISO sensitivity automatic, ISO 80,100,200,400,800, 1600.

Exposure mode program automatic exposure

Exposure Compensation Exposure compensation is also an exposure control method, which is generally about 2-3EV. If the ambient light source is dark, you can increase the exposure value (such as+1EV, +2EV) to highlight the clarity of the picture. 2.0 EV 1/3EV per stage is adjustable.

Data interface type USB 2.0

Functional characteristics

Flash flash is also one of the ways to increase exposure, especially in dark places, which helps to make the scenery brighter. However, when shooting people, the light of the flash may remain in the pupil of the eye, and then "red eye" may appear. Therefore, many camera manufacturers have added the function of "eliminating red eye" in their designs, and before turning on the flash, they first emit weak light to adapt the pupils, and then flash for real to avoid red eye. Automatic flash, automatic red-eye prevention, forced flash, forced non-flash, slow synchronous flash

MPEG-4 video recording is not supported.

Flash distance (m) 30cm-3.5m (wide angle) /30cm-2.2m (telephoto) (ISO automatic)

External flash memory support

White balance adjustment White balance adjustment is white balance. The color of the object will change due to the color of the projected light, and the photos taken under different light conditions will have different color temperatures. For example, a photo taken under the illumination of tungsten lamp (light bulb) may be yellow. Generally speaking, CCD can't automatically correct the change of light like human eyes. Therefore, through the correction of white balance, it will immediately adjust the intensity of the red, green and blue colors of the whole image according to the image characteristics of the current portrait, thus correcting the errors caused by external light. Some cameras provide manual white balance adjustment in addition to automatic white balance or specific color temperature white balance function. Automatic, preset (daylight, cloudy day, incandescent lamp, fluorescent lamp, fluorescent lamp H), customized.

The continuous shooting function is about 1.4 frames per second (large/fine format, LCD off).

Video output support

Short film shooting function A digital camera has the function of shooting video files. Unlike DV (Digital Camera), digital cameras can only store video files in memory cards. Due to the limited memory space, the quality and size of video files are relatively poor. Most of the files used by digital cameras to shoot short films are AVI, and a few cameras can store MPEG4-4 video files. The resolution of video files recorded in AVI format is 320 x 240, and pictures are recorded at the speed of 16 frames per second. Such a video file is very large, and 10 minute can consume 2G of space. The other is a video file in MPEG4-4 format, which is recorded at the speed of 16 frames per second with a resolution of 320x 240. Video recorded in this format is very small. Because of its high image quality and small capacity, the recording mode of MPEG4-4 has been used in many digital cameras. Sony's digital camera can record short films with a resolution of 640 x 480, with a speed of 16 frames per second, which is close to the resolution of 720 x 576 (PAL system) for DV short films, but it still can't reach the recording speed of 25 frames per second for DV. Another recording format is to record short films with a resolution of 160 x 1 12 and a speed of 30 frames per second. The recording speed exceeds the DV band, but the resolution is different. Some digital cameras can record short films on the spot through their own microphones. Most other functions, such as zoom and white balance adjustment, cannot be used when shooting short films. 640×480(20 fps, 20 fps LP mode), 320×240 (30 fps),160×120 (15 fps).

Photometric methods include evaluation photometry, center average photometry and point photometry.

Storage unit

Storage medium Storage medium Image storage medium is a device for storing images in a digital camera, which is generally called a memory card. There are three main specifications of memory cards used in digital cameras in the market: smart media: small in size, cheaper than CF, with a maximum capacity of 64MB, which can be used as a switching device for disk adapter cards, card readers or PCMCIA. COMPACTFLASH: It is more expensive, thicker than SM card, with larger capacity, up to 128MB, and faster. The switching devices are card readers and PCMCIA. Memory stick: At present, it is a special memory specification for Sony and can only be used on Sony machines. Sd, SDHC, MMC, MMCplus, HC MMCplus cards.

Image format Image format Image storage format: Because the image files shot by digital cameras are large and the storage capacity is limited, the images are usually compressed and then stored. The most common image storage formats are JPEG and TIFF files. After JPEG is highly compressed, you can change the file to its original size 1/4, 1/8 or116, which can save a lot of storage space, but also make the original image data lost. Many cameras will provide specific compression ratios for users to choose. TIFF files are almost uncompressed, so images will be more complete than JPEG. However, the higher the image resolution, the smaller the compression and the more memory space it takes up, so it is necessary to take into account the quality requirements of the image and the capacity of the memory card when taking pictures. For example, an 8MB SmartMedia memory card can store 80 photos with 640×480 resolution and high compression format, but if you store photos with 1024×768 uncompressed format, you can only store 3 photos, which is quite different. So be sure to preset the storage mode or simply prepare enough memory cards before shooting. Static: JPEG (EXIF 2.2); Short film: AVI[ picture: motion JPEG]
