According to media reports, Japan FUJIFILM Digital Camera Battery manufacturers Fuji executives have said that this fiscal year, is expected to digital camera sales to rise 25% to 14 million parts, and will likely some production business from the transfer to southeast Asia.

Fuji digital camera FUJIFILM NP-50 Battery department director Takeshi Higuchi in an interview, said that despite the has been to the low-end digital camera is known, but to more lucrative into profits to the Fuji replaceable lens camera market.

In a digital camera FUJIFILM NP-60 Battery, Fuji at present is in the sales market fifth place, behind SONY, Canon, nikon and samsung. Takeshi Higuchi said Fuji confident this fiscal year will be digital camera to boost sales by 25% to 14 million department, and go beyond samsung, ranking fourth market. Takeshi Higuchi expected, and in two years, will be more than nikon in Fuji market third.

At present, Fuji almost all of the digital camera production business all together in China. In order to spread risk, Fuji plan will part production business transfer to southeast Asia, and in the end of this fiscal year site selection decision. FUJIFILM NP-95 Battery

Digital Video,FUJIFILM NP-50 Battery Digital DV = is concerned, relative to the analog to produce stats such as a household VHS Video technology and Laser Disc is simulated, VCD and DVD are Digital. In this sense, the video processing PC is digital.

DV Video format, is Digital = by SONY, panasonic, JVC, sharp, Toshiba, a number of other manufacturers joint proposed a new Digital Video format of household. So-called DV video camera in this format is video data records.

Fundamental index: DV

Bitrate 25 Mbits/s

720x576, 25fps (PAL), 29.97 FPS (NTSC) 720x480

YUV color space 4:2:0 (PAL), YUV color space 4:1:1 (NTSC)

Audio 16bit stereo, 48KHz, better than CD quality

DV MJPEG/MPEG format and what is the same and different

DV core compression algorithm and JPEG/MPEG is same, it is the discrete cosine transform (DCT) and business code. And MPEG different is, DV has not adopted between compression algorithm (movement frame, just compensation) in each frame compression, such, can provide accurate to frame editable sex.

DV and JPEG (MJPEG) different is in the same frame, DV between two field between the field, make the operation compressed code-rate allocation get local optimization, thus obtains MJPEG higher compression ratio than the compression ratio. DV is 5:1, quality MJPEG 3-1 compression of equivalent.

DV quality: -- than format, unlike products

With 10 as the highest, can see the quality of DV than common professional betacam has the sp even slightly better. Of course, here the only format quality compared to consider, equipment quality optical system, the quality of a circuit system.

DV code-rate and storage - I need much hard disk drive?

DV code rate is 3.6 M Chinese/s, basically, 1 minute DV file on the PC is around 200MB, 2gb space can accommodate 9.5 minutes of DV.

The hard disk drive speed requirements: former the non-linear editing system are using SCSI raid high-speed storage system, called av hard drive, because at that time ide hard disk interface backward in technology, driving part is also slow the new hard drive. And now, UDMA33 start from, basic can satisfy DV I/o speed requirements. Main index is to see continued transmission speed, hard drive the ide hard disk can generally be now in 6MB/s above, cope with the 3.6 MB/s DV is enough.

About 2g / 4g avi file size restrictions:

The restrictions have two kind of situations: FUJIFILM NP-60 Battery

1) the operating system itself restrictions, such as maximum 2gb win98 can only support win98se can support documents, to the largest Windows nt / 2000 4g, with NTFS can support an even greater.

2) file format itself restrictions. The old avi1.0 format file maximum limit is also avi2.0 (2G, new OpenDML) without this limit. This is why win98se premiere5.1 maximum file in the only to 2gb, and the media pro6 ulead studio as by one type of avi 2.0 (dv avi Open_DML), there is no this limitation.

What is type1 / type2 DV?

This is Microsoft to dv avi files defined both formats. Type 1 is based on Microsoft's direct display video and audio, file data is the same data flow "ivas" (interleaved stream video & numerous, type 2) is based on the old video for Windows technology, video and audio files respectively in two data stream video stream) : vids (auds (numerous stream) and the type2 vids, actually in, also contains numerous data storage, type2 actually repeat this part of the data, so type2 avi files than type 1 avi files slightly larger.

Desktop video has been based on video for Windows technology, type2 DV avi adopts VFW format storage, so compatibility is better some, most video software can handle. Type 1 DV before the year 2000 get support is limited, for example premiere5.1 cannot support type 1 DV AVI. The earliest support type 1 DV ulead's media are pro6 and video studio studio 3 DV edition. To now as Directshow technology promoted, type 1 DV support is also getting better, now premiere 6 can also support type 1 DV.

YCrCb) and YUV (4:1:1, 4:2:2, 4:2:0

Refers to brightness signal Y and red/blue poor signal sampling formats. In dv, NTSC is 4:1:1, Pal 4:2:0. Note that by 4:2:0 not blue poor signal sampling is 0, but, compared with 4:1:1 in a horizontal improve 1 times sampling frequency, in color with Cr/vertical half way of reducing interval Cb sampling.

Photographer FUJIFILM NP-50 Battery in filming, metering mode when portrait photo of choice is very important. Metering mode is equipped with advanced metering means DSLR system to measure the shooting scene way exposure. Most of the film cameras only support a metering mode. Along with the development of digital technology, now many digital cameras all supports multiple metering mode.

Evaluation metering is the most common metering mode, which is shown in all of viewfinder elements can be adjusted and draw value method of budget allows. Evaluation metering was known as a multizone metering, matrix metering, evaluation of regional metering film, the film is, matrix perturbation screen divided into multiple areas respectively after the judge each area, exposure, and provide appropriate exposure value method. In the more than nikon 100.5 pixel regional side light, for example, put the viewfinder screen divided into 1005 an area, the camera automatically calculate after exposure value. All of the brightness of the picture on average estimates scenery after a suitable to compute a proper exposure value, this is the principle of evaluation metering. FUJIFILM NP-60 Battery

In filming, not consider portrait photo shoot conditions, simple for brightness, will exist average measure certain error. Evaluation metering mode normally used in the light contrast not obvious case also is the light even situations. Metering focuses on focus area to other regions, and the average metering roughly. This way is simple to use, but when scene projection on the character of the light and ambient light upon the brightness difference is very big, accuracy, it is hard to guarantee.

For example, models, pat backlight turn your back to the sun when background is like the light and models face very dark. Photographer want models of accurate exposure, pat face of effect it is background is bright, model is very dark. This is because the metering system than camera background to calculate the average bright, model is better than average dark, so in this case was about to undertake exposure compensation.

Evaluation metering modes also suitable for frontlighting cases or use scattering light.

This way is not the image by time or place can use at any time, but the average metering effect sometimes not very satisfactory, and total in this metering method, photography technology is also difficult to have improved. Therefore, the average metering mode for beginners to use, and in this mode shooting rarely gets unique works.

Shun side light, the light is more homogeneous, with evaluation, exposure metering mode metering accurately. FUJIFILM NP-95 Battery
