现在我们的手机上都配备了照相功能，并且功能越来越强大，可以说是人手一部数码相机，随时随地可以拍照分享，让我们的生活更加丰富多彩。

三、世界上第一台数码相机是什么时候发明？

是1975年发明的。

赛尚（Steven Sasson)1973年硕士毕业后即加入柯达，成为一名应用电子研究中心的工程师。1974 年，他担负起发明“手持电子照相机”的重任。次年，第一台原型机在实验室中诞生，他也成为“数码相机之父”。

“当原型机第一次展示给投资者时，他们询问这种产品何时可以成为消费者品，我回答，大概是15～20年这种产品才会走进普通消费者家庭。”

赛尚的判断相当准确，数码相机的发展是一条漫长的道路，在1970末到80年代初，柯达实验室产生了1千多项与数码相机有关的专利。

奠定了数码相机的架构和发展基础，让数码相机一步步走向现实。1989年，柯达终于推出了第一台商品化的数码相机。

发展简史

数码相机的历史可以追溯到上个世纪四五十年代，1951年宾·克罗司比实验室发明了录像机（VTR），这种新机器可以将电视转播中的电流脉冲记录到磁带上。到了1956年，录像机开始大量生产。它被视为电子成像技术产生。

四、世界第一台数码相机是谁家什么时候做成并上市的？

1981年，SONY生产第一架商用无胶卷电子相机，可把图像记录到磁盘中在电视上观看，摄影从此可以脱离胶卷。

1986年，柯达公司发明了第一台兆像素数码相机，可惜柯达公司却将这一技术雪藏，为了防止其对胶片相机的冲击。1990年柯达公司推出图片专用CD格式，来储存并在电脑上观看图片。

1991年柯达推出世界第一款专业数码相机，他是在尼康F3基础上改造，使用了一块1.3M像素的CCD，并进行了量产。

五、数码相机为什么叫数码相机？

顾名思义，数码相机它摄影获得的成果是数字信息，它与胶卷相机区别在于，胶卷相机拍摄曝光是胶片涂层的化学反应，胶卷获影像(需冲洗)；而数码相机拍摄曝光过程是感光元件光电转换过程、获得的是数字信号信息存入内存卡里，数码相机最大好处是不需要使用胶卷这种耗材。

六、维修数码相机，怎样给数码相机放电？

镍镉电池需要放电后充电,否则容易有记忆效用.

镍氢电池虽然记忆效用比较轻,也最好采用用光充足的使用策略.一般在使用一段时间后,采用充分放电充分充电一次,来激活电池的最大容量.

锂电的记忆效用可以忽略不计,所以充电前不必放电.

有的针对镍镉电池专用的充电器,本身带放电功能,放完电后自动转为充电状态.

如果想用数码相机多用电来完成电池放电过程,对数码相机来说是无谓磨损,得不偿失,还是不使用这种方法为好.

建议把电池放到电动玩具或者用使用电池的各种电器里使用,最好是工作电流比较大的那些电器,那样放电时间可短些.

七、卡片数码相机？

照相机是记录静态图片的光学仪器，根据记录介质分为传统的胶片相机、拍立得相机（波拉片）和数码相机（记录为数字化图片文件）。

数码相机作为照相机的一大类，又根据镜头配置分为可更换镜头的和不可更换镜头的相机。

可更换镜头数码相机又分为可更换单镜头反光取景器数码相机（俗称数码单反）和可更换单镜头电子取景器数码相机（俗称单电，索尼将微型机身的单电称为微单，以便与其酷似单反外形但使用电子取景器的单电相机相区别）。

不可更换镜头数码相机又分为超薄数码相机即俗称的卡片机，还有一类拥有超大变焦比（30倍以上）镜头的大变焦数码相机，因为等效焦距可达到600-1200mm，又简称为长焦数码相机（其实其多数也拥有24mm的广角）。这类相机镜头硕大，其实不能称之为卡片机了，其外形酷似单反，又称为类单反相机。

八、YASHICA数码相机？

《雅西卡》、日本二、三流的相机厂商，这个一台数码LOMO相机，随便玩玩。

有一个概念问题必须搞清楚：变焦和对焦是两回事，更没有自动变焦一说，只有自动对焦！！！

这是一台数码傻瓜机，没有变焦镜头，只是一个定焦镜头，更没有自动对焦系统，只有手动对焦 ，太傻瓜了，不值得买！

九、数码相机好吗？

数码相机优点就是:立拍立刻可以看到效果；出照片快，连上无线，就可以立即打印出照片；修改方便；传输方便 有网的地方，随拍随时可以传到任何有网的地方。

缺点就是耗电大，没有电彻底趴窝；存储卡一旦损坏，所有的心血白费。

十、单反数码相机和消费数码相机的差别？

单反相机和数码相机的区别如下：第一个区别：取景方式的不同。单反是以光学的取景方式，涉及的元器件有反光板和五棱镜。微单它是采用的是电子取景方式——直接用镜头捕捉影像，然后把它转化为电子图象。第二个区别：对焦速度不同。单反的对焦速度会快一点，而数码类的微单，会比较慢一点。第三个区别：宽容度不同。最终的细节，比如说太亮或者太暗的bufen ，数码相机细节丢失很严重。第四个差别：重量不同。数码相机较轻，而单反相机非常重。出去玩如果要背台单反，滋味可不好玩。第五个差别：价格不同。一般来讲，单反都是要比微单价格要贵很多。对数码相机而言，感光元件的尺寸是影响成像质量最直接也是最关键的因素，感光元件越大，则成像质量越高。数码单反相机感光元件尺寸远远超过了普通的消费型数码相机，达到了十几甚至数十倍之多，这就意味着同样为1000万像素的数码单反相机和消费型数码相机，前者在表现打个像素时，拥有更大的感光元件面积进行表现，这也就不难理解数码单反相机拥有更优异的成像质量了。

One, is the first had turn over digital camera?

The first is not had turn over camera to was released in September 2008, it is the DMC-G1 below the pine, use 4/3 inch CMOS. The first APS-C is not had turn over camera to was released in January 2010, it is SamSung NX10.

3, when is camera of the first number to invent?

Invented 1975.

Contest still (Steven Sasson)1973 year Kodak is joined namely after the Master graduates, become an engineer that uses electronic research center. 1974, he loads an invention " hold electronic camera " important task. Second year, the first archetypal machine is born in the lab, he also is become " the father of digital camera " .

"When archetypal machine first time shows investor, they enquire when this kind of product can become consumer to taste, I reply, it is 15 ～ 20 years probably this kind of product just can walk into average consumer family. It is 15 ～ 20 years probably this kind of product just can walk into average consumer family..

Contest still judgement is quite accurate, the development of digital camera is a long way, arrive in 1970 end at the beginning of 80 time, kodak lab produced more than 1000 1 patent that concern with digital camera.

Laid the framework of digital camera and development foundation, let digital camera move toward reality step by step. 1989, kodak rolled out the first commercial number camera eventually.

Patulous data:

Develop brief history

The history of digital camera is OK restrospect to last centuries 449 time, guest · overcame collect department to invent videocorder than the lab 1951 (VTR) , this kind of new machine is OK board the voltaic pulse record in television relay to tape. Arrived 1956, videocorder begins mass-produced. It is regarded as an electron to become arise like the technology.

4, whose home is camera of the first number of world when make it appears on the market?

1981, SONY produces the first business to use without film electron camera, can record image in disk to be watched on TV, photography can break away from film from now on.

1986, kodak company invented the first million to pile up camera like prime number, regrettablly Kodak company hides snow of this one technology however, be opposite to prevent its the concussion of film camera. Kodak company rolled out a picture 1990 special CD format, will store and the photograph is watched on computer.

Kodak rolled out camera of the first professional number of world 1991, he is transform on foundation of Ni Kang F3, used a 1.3M to resemble the CCD of element, undertook measuring yield.

5, why does digital camera call a number camera?

Just as its name implies, the gain that its photography scores digital camera is digital information, it and film camera distinction depend on, film camera films exposure is the chemical reaction of film coating, film is obtained video (need to rinse) ; And digital camera films exposure process is transition of sensitive component photoelectricity, those who obtain is digital signal information stock memory Carrie, digital watch for an opportunity is the greatest advantage is not to need to use film material of this kind of bad news.

6, maintenance number camera, how to give digital camera discharge?

After need discharges, nickel cadmium cell charges, have memorial effectiveness easily otherwise.

Although nickel hydrogen batteries remembers effectiveness lighter, also had better use the use strategy with enough consumed. After using period of time commonly, use sufficient discharge to charge adequately, will activation of batteries most high capacity.

The memorial effectiveness of lithium report is negligible not plan, before charging so, need not discharge.

Some is aimed at charger of appropriative of nickel cadmium cell, itself takes discharge function, put electric hind to turn automatically to charge condition.

If want to use digital watch for an opportunity multi-purpose report will complete batteries discharge process, it is meaningless to digital camera wear away, the loss outweights the gain, still do not use this kind of method had better.

Suggest to be used in all sorts of electric equipment that put batteries to dynamoelectric toy to perhaps use use cell, had better be those electric equipment with working older electric current, discharge in that way time but some shorter.

7, card number camera?

Camera is the telescope that records static picture, the film camera that is a tradition according to recording medium to divide, pat stand camera (Paula piece) with digital camera (the record is digitlization picture file) .

Digital camera serves as a kind big of camera, it is according to cent of camera lens configuration again can change of camera lens and cannot change the camera of camera lens.

Can change camera of camera lens number is divided again to can change camera of number of single shot reflex viewfinder (common says digital sheet is turned over) and can change camera of number of viewfinder of single shot electron (common weighs only report, the only report of airframe of miniature of Suo Ni general calls small sheet, so that be exactly like sheet with its,return an external form but the photograph of only report camera of use electron viewfinder is distinguished) .

Cannot change camera of camera lens number is divided again for ultrathin number camera namely the card chance that common weighs, still one kind is had exceed big scorch to compare (30 times above) the camera of big scorch number of camera lens, because equivalent focal length can achieve 600-1200mm, abbreviation is camera of long anxious number (the wide part that actually its majority also owns 24mm) . Camera lens of this kind of camera is huge, cannot say actually be card machine, its appearance is exactly like sheet to turn over, call kind of sheet to turn over camera again.

Digital sheet is turned over

Only report camera

Card machine

Kind sheet turns over camera

8, YASHICA number camera?

" Yaxika " , Japan 2, small-time camera manufacturer, camera of LOMO of this a number, play casually.

Problem of a concept must make clear Hunan: Scorch and right anxious it is two different matters, do not have automatic scorch to say more, be opposite automatically only anxious! ! !

This is a number goofy machine, without scorch camera lens, it is one focuses camera lens only, do not have more be opposite automatically anxious system, only the hand is moved right anxious, too goofy, undeserved buy!

9, is digital watch for a chance good?

Is digital camera advantage: ? Key of tip of charcoal of ⑴ herd ⒖ blows  of  of Yu of  of palm of Huai Su of  calling Ч to hold Gan Lu  to besmear ⒓ of tip another name for Guangdong Province achieves award of Mu of Ru of suddenly of  of palm of Qi 〕 revive to be contrary to the place that? of award of Zhuo of  of the Huaihe River has a net, along with take the place that can spread a net at any time.

Defect is bad news report big, bend over thoroughly without report nest; Once memory card damages, all painstaking effort waste.

10, the difference that sheet turns over digital camera and consumptive number camera?

Sheet turns over the distinction of camera and digital camera to be as follows: The first distinguishs: Of means of find a view different. Sheet is the means of find a view with optics instead, yuan of involved parts of an apparatus have glance board with 5 prism. Small sheet it is those who use is means of electronic find a view -- catch with camera lens directly video, next image of electron of its translate into. The 2nd distinguishs: Different to anxious speed. What sheet turns over will be a bit faster to anxious speed, and number kind small sheet, the meeting is a bit slower. The 3rd distinguishs: Latitude is different. Final details, for example too bright too dark perhaps Bufen, digital camera detail is missing very serious. The 4th difference: Weight is different. Digital camera is smaller, and sheet turns over camera very heavy. Go out to if want to carry stage sheet on the back to turn over,play, flavor but not amused. The 5th difference: The price is different. Will tell commonly, sheet is to want than tiny monovalent square instead a lot of more expensive. logarithm code camera, the dimension of sensitive component is to be affected resembling quality also is the most crucial factor directly most, sensitive element is larger, become taller like quality. Digital sheet turned over dimension of camera sensitization component to exceed watch for an opportunity of average consumption number far, achieved ten even tens of of times, this is meant turn over camera of camera and consumption number for the 10 million number sheet that resembles element likewise, former hit in expression when resembling element, have larger sensitive component area to have show, sheet of this not fathomless also number turns over camera to have more exceedingly good into resemble quality.
