Vancouver, BC, Canada ― (June 9, 2003) ? Creo Inc. (NASDAQ: CREO; TSX: CRE) announces the Leaf™ Valeo 22 digital camera back for in studio and portable shooting. It utilizes a newly developed 22 megapixel CCD that is designed for medium and large format photography. In studio, the Leaf Valeo 22 camera back features live video view and electronic shutter control. On location, the Leaf Valeo 22 offers one of the fastest capture rates in the industry and a burst rate of eight frames. A detachable 6 x 7 cm display and removable Digital Magazine provides Leaf Portable Power. Demonstration units are available from July 2003 and commercial shipments begin September 1, 2003.

New Technologies
The Leaf Valeo 22 camera back contains a mega-sized sensor. The 4,056 x 5,356 resolution in a sensor size of 48 x 36 mm provides exactness and diminishes moiré issues. Raw data files reach 126 MB in 16 bit. Advanced imaging technologies include the 16 bit Leaf High Dynamic Range (HDR) raw data format; Leaf double-sensor-readout (DSR) technology, and the 512 MB internal memory buffer for eight fast continuous frames. Other features include:

Full lens coverage: The CCD imaging area fits the 6 x 4.5 lens-coverage. Focal length needs minimal conversion, thus lens perspective usage is the same as with film. The 3:4 classic photographic ratio is efficient and minimizes cropping.
Fast frame rate: The fast capture speed is achieved with a unique DSR technology that doubles the capture rate without sacrificing image quality.
In Studio ? Large Format Power
The Leaf Valeo 22 camera back features a complete digital solution for the studio photographer. An optional large format solution includes live video view, and electronic control of shutter speed and aperture. This allows the photographer to compose, focus and adjust lighting by viewing the large computer monitor. The shutter speed, aperture steps in 1/10 f-stop intervals, and electronic control allow the Leaf Valeo 22 to capture accurate and consistent images.

On-location ?Portable Power with 22 Million Pixels
The entire Leaf Valeo camera back family integrates optional Portable Power, a unique approach for portable professional digital photography with innovative solutions for image storage and display. The Leaf Valeo camera back works with a removable 5 GB or 10 GB Leaf Digital Magazine for storing hundreds of uncompressed 16 bit images. The Leaf DP-67 is a detachable 6 x 7 cm image display and control unit based on the HP iPAQ pocket PC. It acts as both a “digital proof” and a “personal photographic assistant”.

The Leaf Valeo 22 fits into the established Leaf workflow consisting of the Leaf™ Capture V8 and Leaf™ oXYgen image and editing applications, which cover all needs from capture to RGB/CMYK print.

新技术

  Leaf Valeo 22数码机背有一个大尺寸的影像传感器。在48x36mm的传感器上实现的4056x5356的分辨率能提供更高质量的图像。原始图像数据文件以16位的方式存储达126MB。先进的图像技术包括16位的Leaf高动态范围(HDR);Leaf双传感器读取(DSR)技术;以及用于支持高速连拍的512MB缓存。其他技术还包括:

   ・适用镜头:CCD成像区适合6x4.5以上的镜头。由于该CCD尺寸比例6x4.5cm画幅比例接近,因此,镜头视角的使用就和传统胶片相似。3:4的经典图象比例可以有效地避免不必要的裁剪。

   ・高帧频率:有了独一无二的双传感器读取(DSR)技术的支持,可以在实现高连拍速度的同时,又能不牺牲图片质量。

室内摄影――强大的模式

  Leaf Valeo 22是室内摄影的绝好数字化的拍摄工具。大容量、光学取景,以及快门光圈速度的电子控制,这些设置都帮助拍摄者在电脑显示器上实现实时监控。光圈和快门速度,都可实现1/10级调节,结合电控系统,保证了Leaf Valeo 22能拍摄到更加精确、完美的影像。

外景拍摄――2200万像素的便携式电源

  整个Leaf Valeo家族系列的机背都可以使用便携式电源,这是轻便的专业数码摄影解决图象存储和显示的独特方式。Leaf Valeo机背工作时配有5GB或10GB的Leaf数字存储器以存放数百张16位的未经压缩的图片。Leaf DP67是一台6x7cm的图象显示器,它的控制器是建立在惠普iPAQ掌上电脑的技术基础之上的。它扮演的是双重角色:“数字化校验”和“个人图片助理”。

  Leaf Valeo 22 有它自己的工作程序,由Leaf Capture V8和Leaf oXYgen图像和编辑软件构成,这完全能适应RGB或CMYK的打印工作。
