Sony FCBEH3300 Product Manual (Tehnical Manual for new HD Block Cameras) - Page 4

Overview Precautions Software Use of the demonstration software developed by Sony Corporation or use of the software with customer developed application software may damage hardware, the application program or the camera. Sony Corporation is not liable for any damages under these conditions. Operation Start the camera control software on your computer after you turn on the camera and the image is displayed. Operation and storage locations Do not shoot images that are extremely bright (e.g., light sources, the sun, etc.) for long periods of time. Do not use or store the camera in the following extreme conditions: • Extremely hot or cold places (operating temperature -5 ˚C to +60 ˚C (23 ˚F to 140 ˚F)) • Close to generators of powerful electromagnetic radiation such as radio or TV transmitters • Where it is subject to fluorescent light reflections • Where it is subject to unstable (flickering, etc.) lighting conditions • Where it is subject to strong vibration • Where it is subject to radiation from laser beams Care of the unit Remove dust or dirt on the surface of the lens with a blower (commercially available). Other • Do not apply excessive voltage. (Use only the specified voltage.) Otherwise, you may get an electric shock or a fire may occur. • The CMOS image sensor and IC included in this camera may break if exposed to static electricity. When directly handling this camera, wear an antistatic strap, spread a conductive sheet or similar item under your workbench, and take measures to eliminate static electricity. In case of abnormal operation, contact your authorized Sony dealer or the store where you purchased the product. Phenomena specific to CMOS image sensors The following phenomena that may appear in images are specific to CMOS (complementary metal-oxide semiconductor) image sensors. They do not indicate malfunctions. Rolling shutter As CMOS image sensors use shutters that capture images line-by-line, there is a slight time difference between the top and bottom of an image. As a result, images may appear skewed if the camera is moved. White flecks Although the CMOS image sensors are produced with high-precision technologies, fine white flecks may be generated on the screen in rare cases, caused by cosmic rays, etc. This is related to the principle of CMOS image sensors and is not a malfunction. The white flecks especially tend to be seen in the following cases: • when operating at a high environmental temperature • when you have raised the master gain (sensitivity) • when operating in Slow-Shutter mode Aliasing When fine patterns, stripes, or lines are shot, they may appear jagged or flicker. Phenomena Specific to Lenses Ghosting If a strong light source (e.g., the sun) exists near the incidence angle of the lens, bright spots may appear in the image due to diffuse reflection within the lens.
