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。 二十世纪六十年代美国宇航局(NASA)在宇航员被派往月球之前,宇航局必须对月球表面进行勘测。然而工程师们发现,由探测器传送回来的模拟信号被夹杂在宇宙里其它的射线之中,显得十分微弱,地面上的接收器无法将信号转变成清晰的图像。于是工程师们不得不另想办法。在这之后,数码图像技术发展得更快,主要归功于冷战期间的科技竞争。而这些技术也主要应用于军事领域,大多数的间谍卫星都使用数码图像科技。 早在20世纪60年代,就开始了“CCD芯片”的研究与开发,1969年,贝尔实验室的George Smith和Willard Boyle将可视电话和半导体泡存储技术结合,设计了可以数码相机沿半导体表面传导电荷的“电荷‘泡’器”(Charge “Bubble” Devices),率先发明了CCD器件的原型。 当时发明CCD的目的是改进存储技术,元件本身也被当作单纯的存储器使用。随后人们认识到,CCD可以利用光电效应来拍摄并存储图象。
1975年美国纽约柯达实验室中诞生了世界首台数码相机。这台数码相机的发明人是柯达公司的技术人员StevenJ.Sasson(赛尚)。发明者是美国人赛尚(steven
sasson)。
赛尚,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”。

数码相机最早出现的时间是1972年,在美国的德克萨斯州由仪器工程师Texas Willis Adcock,设计,不过第一台商用的数码相机应该是1981年索尼所推出的数码相机Mavica。 而在之后的1994年2月,苹果公司推出了QuickTake 100相机,一款面向普通大众的数码相机,之后其他厂商迅速跟进,出现了柯达DC40、卡西欧QV-11和索尼Cyber-Shot等一系列经典的数码相机。
爱德华。
剪刀是古埃及人爱德华发明的。 剪刀是一种切割布、纸、绳等片状物体和线状物体的工具,在生活中非常的常见,它的双刃具有一定的锋利性,所以在使用的时候要小心谨慎,剪刀的出现时间很早,在公元前15世纪,古埃及人就已经在使用青铜做的剪刀了,它是由古埃及人爱德华发明,在埃及的孔翁破神殿上就刻画着一些剪刀和其它医学工具,所以专家学者们认为是埃及人首先使用了外科手术技术。
锯子是18世纪德国发明家夏尔·勃兰特(Thales von Ranzow)发明的。他在1803年发明了第一台手动式锯子,这是一台横向削减木材的机器,并且可以一次性将木材削成许多不同形状的片断。此后,锯子的设计也在不断地发展。
盲文的发明者是:路易·布莱尔(Louis Braille),也有人翻译为刘易斯·布莱叶。他1809年1月4日出生在法国一个贫苦的马具匠家里,他3岁时玩弄工具时不慎失手,刺伤了一只眼睛,不久又感染另一只眼睛,以致双目失明。
布莱叶的父母没有放弃对这个盲孩子的培养。父亲在木板上用钉子组成字母,教他认字,后又送他到村里的小学读书。布莱叶学习既刻苦又聪明,深受老师和校长的喜爱
浑天仪的发明者是张衡。浑天仪是古代中国天文学中的重要仪器之一,用于观测星宿位置和预测天象。张衡是东汉时期的天文学家、地理学家和数学家,他发明的浑天仪是古代中国传统的用于测定恒星位置与方位的天文仪器,实现了中国古代对天体运动规律的认识和研究。张衡在天文学、地理学和测量学方面的成就和贡献,对中国古代和近代科学技术的发展都产生了深远的影响。为扩展延伸,可以介绍张衡在其他科学领域上的成就,如设计水利控制工程、制造定量器、著作《西京杂记》等。
现代牙刷是由美国人威廉·亚当斯·布克斯于1938年发明的。 原因是在此之前,人们只能用手指或者粗硬的棉布清洁牙齿,很难达到深层清洁的效果。布克斯的牙刷刷毛细软,拥有更好的刷牙效果。 早在公元前3000年左右,埃及人就开始用绿玉制作的棍子上绑上毛发,用作口腔清洁工具。而中国古代则使用猪鬃或狼毫制成的牙刷,这些牙刷形状类似于现在的刷毛。随着时代的进步以及科学技术的发展,牙刷的使用方式和材质也不断更新换代,现在市场上有许多不同材质和设计的牙刷供人们选择。

He invented saw of the first hand 1803, this is transverse the machine that cuts timber, and can one-time the segment that cuts timber figure. After this, the design of saw also is developing ceaselessly.
The contriver of braille is: Er of Lai of cloth of road easy · (Louis Braille) , also somebody is translated for Liu Yi Si Bulaixie. He was born in France on January 4, 1809 in a poor harness artisan home, when he employs a tool when 3 years old inadvertent accidentally drop, stabbed an eye, catch another eye again before long, as a result loses the sight.
Bulaixie's parents did not abandon the education of pair of this blind children. Father composes a letter with nail on board, teach him know how to read, the elementary school that he sends in the village again after reads. Bulaixie study already assiduous clever, get of teacher and president love
The contriver of armillary sphere is Zhang Heng. Armillary sphere is one of important instruments in archaic China astronomy, use at observation constellation position to mix forecast astronomical phenomena. Zhang Heng is the astronomer of period of the Eastern Han Dynasty, geographical home and mathematician, the armillary sphere that he invents is archaic China tradition use at determining the astronomy instrument of sidereal position and azimuth, realized the understanding of Chinese ancient time to celestial body motion curve and research. Zhang Heng is in astronomical, geographical and measure the achievement that learns a respect and contribution, produced far-reaching effect to the development of Chinese ancient time and recent science and technology. Exhibit for enlarge outspread, can introduce the Zhang Heng achievement on other and scientific domain, if design project of irrigation works control, production ration implement, composing " on the west capital notes " wait.
By Adam of American Williams · Si Bukesi invented contemporary tooth brush 1938. The reason is to be before this, people can point to with the hand only or thick tooth of hard cotton cloth cleanness, the effect of very inaccessible deep-seated cleanness. Bukesi's tooth brush brushs wool delicacy, it is better to have brush one's teeth the effect. Be in early BC was controlled 3000, bind on the stick that Egyptian begins to be made with aquamarine on hair, use as oral cavity cleaner is provided. And the toothbrush that Chinese ancient time uses bristle or a writing brush made of weasel's hair makes, these tooth brush appearance are similar to present brush hair. As the development of the progress of the times and science and technology, the use means of tooth brush and material also change ceaselessly character, now in the market the tooth brush that a lot of different capable person pledge and designs chooses for people.
