To convert an image from the bayer format to an RGB per pixel format, we need to interpolate the two missing color values in each pixel. T. Sakamoto, C. Nakanishi and T.

Frankly, our engineers had enough. Their spudgers were getting soft; we needed to do something that would present a *challenge* and get them sharp again -- none of the take-off-a-display-to-find-a- motherboard baloney. We knew exactly where to turn. We've done a set of Nikon D70 repair guides in the past, and we saw how difficult it was to take apart an SLR. What better way to infuse a bit of fun in our teardowns than taking apart another SLR? So, in the name of science and all that is right in this world, let's see what's inside the brand-new Nikon D5100!

The major restructuring replaced the managing directors of all the eight subsidiaries of KPC and appointed new executives for companies like Kuwait Oil Co (KOC), the oil production arm of KPC, Kuwait National Petroleum Co (KNPC), which operates the three refineries for Kuwait, and others. Under the move, KOC managing director Sami Al- Rasheed, the most veteran oil executive, was among top oil officials who lost their jobs. He was replaced by Hashem Hashem. KNPC managing director Fahad Al- Adwah was also among those who were forced to retire and was replaced by Mohammad Al-Mutairi. Maha Mulla Al-Tarkait, the managing director of Petrochemicals Industries Co (PIC), also lost her job to Asaad Al-Saad. Tarkait and several other leading officials at PIC were suspended on Thursday over the $2.2 billion penalty payment to US’ Dow Chemical and the whole issue was referred to the public prosecution.

  • Panasonic Lumix DMC-LX1EG-K
    Panasonic Lumix DMC-LX1EG-K The DMC-LX1 features a 4x optical zoom with a 28 to 112mm wide-angle capability (35mm equivalent). This and a 1/1.65" diagonal CCD with 8.4 million effective pixels give you superb image quality over a wide shooting range. The Extended Optical Zoom, which minimizes the image degradation that normally occurs with digital zooming, gives you up to 5x zooming power. Plus, the 4x optical zoom and 4x digital zoom can be used together to produce a maximum of 16x zooming power.The DMC-LX1 features a 2.5" diagonal high-resolution LCD monitor - surprisingly large for such a compact camera. This high-quality, 207, 000-pixel display makes it easy to see your subject. For easier viewing when shooting outdoors on a sunny day, press the Power LCD button to boost the backlighting by about 40%.Jitter from shaky hands is one of the main reasons why cameras produce blurry images. Not everyone has hands of stone when taking pictures - that's why Lumix cameras help solve the problem of unsteady hands with advanced MEGA Optical Image Stabilizer technology. The DMC-LX1 has a built-in gyrosensor that detects any hand movement and relays a signal to a tiny microcomputer inside the camera, which instantly calculates the compensation needed. A linear motor then shifts the Optical Image Stabilizer lens as necessary to guide incoming light from the image straight to the CCD. You won't even notice it working - all you'll see are the outstanding results!In addition to displaying the settings in large, easy-to-understand text, the large, 2.5" diagonal screen with 230, 000-pixel resolution lets you show up to 25 thumbnail images at once.
