	Micro-motion exposure method based on PZT piezoelectric ceramics (EI CONFERENCE) 会议论文 OAI收割 International Symposium on Photoelectronic Detection and Imaging 2009: Material and Device Technology for Sensors, June 17, 2009 - June 19, 2009, Beijing, China 作者: Meng Z.; Meng Z. 收藏 \| 浏览/下载：103/0 \| 提交时间：2013/03/25 There mainly is laser digital photofinishing technique and digital photofinishing technique based on LCD consisting of TFT and LCOS in the digital photofinishing field at the present time. The former have a good many merit such as wide color gamut high processing rate large output size and high brightness but his cost is very high his maintain technique being comparatively complex that result in difficult use for people. The utilization ratio of the latter is low because of lower resolution and lower aperture ratio for LCD but the digital photofinishing based on LCD have lower cost and higher utilization ration being suitable for people's current standard of living. Considering above mentioned problem a micro-motion exposure method based on PZT piezoelectric ceramics used in digital image photofinishing is presented. The two-dimension micro-motion exposure system consisting of PZT piezoelectric ceramics LCD panel polarizing film and spring strip is designed. By means of PZT piezoelectric ceramics the LCD panel is removed about the one half of the pixel size of the LCD panel for four times from the original place at the same time imaging system is exposed four times at the printing paper. The software is used to control the time synchronization the exposure time and motion range of the LCD panel. The system has advantages such as shorter response time than 0.1seconds lesser motion error than 0.01 microns high stability and repeatability. Experimental results show that the proposed micro-motion exposure method improve the picture brightness and enlarge output size at the meantime reducing the cost of the system. 2009 SPIE.
	The deviation of color matching algorithm in the field of full-color LED display (EI CONFERENCE) 会议论文 OAI收割 2009 2nd International Congress on Image and Signal Processing, CISP'09, October 17, 2009 - October 19, 2009, Tianjin, China 作者: Wang Y.; Chen Y.; Zhang X.; Zhang X.; Zhang X. 收藏 \| 浏览/下载：19/0 \| 提交时间：2013/03/25 In this paper a color gamut transformation method which transformed the different color gamut into a same one has been proposed. In the transforming process the deviation which was arose from the quantization error and the truncation error were existing. If the deviation was out of the color tolerance the uniformity of the screen color will be deteriorated. Firstly the color tolerance of vision was calculated by the color-difference formula. Secondly in the full-color LED display experiments it was analyzed that the tri -color tolerance values are respectively 2.5 2.8 and 1.3. According to the tri -color tolerance values and the color difference formula the express of the quantization precision gray value and the color difference was set up. Finally the gray-scale range of the color uniformity was analyzed by the collected data it was concluded that the uniformity of the display was satisfied the requirement of the visual when the range of the gray level was [11 14] and when the range was [1 11] the value of the color difference was also reduced significantly. 2009 IEEE.

	The application study on building materials with computer color quantification system (EI CONFERENCE) 会议论文 OAI收割 ICO20: Illumination, Radiation, and Color Technologies, August 21, 2005 - August 26, 2005, Changchun, China 作者: Yu H.; Li Z.; Li Z. 收藏 \| 浏览/下载：26/0 \| 提交时间：2013/03/25 The first impression of any building to a person is its exterior and decoration therefore at the same time and therefore the quality of decoration project shows the more important position in building project. A lot of projects produce quality problem because of the material color difference how to grasp and control the color change of building materials the color difference problem laying stone materials is also studied in this paper which exists universally at the common project and carry out color quantification and the solution scheme has been given using this system. and is often found at the high-grade decoration it has the very important meaning. According to the color theory a computer vision system used in color quantification measurement is established the standard illuminant A is selected as the light source. In order to realize the standardization of color evaluation the mutual conversion between RGB and XYZ color space is studied which is realized by the BP network. According to the colorimetry theory the computer program is compiled in order to establish the software system and realize the color quantitative appraisement in whole color gamut. LCH model is used at quantifying the color of building materials and LaV model is used at comparing the color change. If the wooden floor is selected and laid improperly during family fitment it is easy to present "flower face". The color also arises greater discrepancy using the laths of same tree. We can give the laying scheme using the color quantification system
	The research of chromatic aberration arose from the deviation of same function family at the single primary in full-color display (EI CONFERENCE) 会议论文 OAI收割 ICO20: Illumination, Radiation, and Color Technologies, August 21, 2005 - August 26, 2005, Changchun, China 作者: Chen Y. 收藏 \| 浏览/下载：15/0 \| 提交时间：2013/03/25 The deviations of primary display characteristics often bring about many complex chromatic aberrations on the color gamut. Among kinds of existing situations caused by deviation of primaries the emphasis of this paper is confined to the deviation of same function family at the single primary for smoothing away differences. The purpose of this paper is two fold. First luminance aberration of facsimile color which arises out of special deviations is discussed from many aspects and the three-dimensional gamut model of luminance aberration is proposed. The second goal is drawn on the color aberration arose from these deviations of primaries and the three-dimensional gamut with vectors has been introduced to demonstrate the feature of these aberrations whereas the difficulties of describing the distribution of color aberration. All these conclusions can be utilized to appraise the quality of the display fidelity.
