Television Production Chapter 5

A camera control unit (CCU) is a separate equipment from the camera head that is responsible for controlling various video settings such as color fidelity, color balance, contrast, and brightness. It allows the user to adjust these settings to achieve the desired image quality and consistency. The CCU is an essential component in professional video production as it enables precise control over the visual aspects of the footage.

Hue is one of the three basic color attributes, along with brightness and saturation. It refers to the dominant wavelength of light and determines the perceived color of an object. Hue is what allows us to distinguish between different colors such as red, blue, and green. It is an essential component in color theory and is used in various fields such as art, design, and psychology to create visual appeal and convey different emotions.

The correct answer is "Contrast Ratio." Contrast ratio refers to the difference between the brightest and darkest portions of a picture. It is a measure of the range of brightness levels that a display can produce. A higher contrast ratio indicates a wider range and better differentiation between light and dark areas, resulting in a more visually appealing and detailed image.

White balance refers to the adjustment of the color circuits in a camera to produce a white color in lighting of various color temperatures. Different light sources emit light with different color temperatures, such as warm (yellowish) light from incandescent bulbs or cool (bluish) light from daylight. The white balance setting on a camera helps to ensure that white objects appear truly white in photographs or videos, regardless of the lighting conditions. By adjusting the color circuits, the camera can accurately reproduce colors and maintain a natural-looking image.

A pixel is a single imaging element that can be identified by a computer. It refers to the light-sensitive elements on a CCD (charge-coupled device) that contain a charge. In digital imaging, pixels are used to represent the smallest unit of an image, and they combine to form the overall resolution of the image.

The correct answer is "Sensor". In a video camera, the CCD or CMOS imaging device is commonly referred to as the sensor. This sensor captures the light and converts it into an electrical signal, which is then processed to create the video image. The sensor plays a crucial role in determining the quality and clarity of the video footage captured by the camera.

Brightness refers to the attribute that determines how dark or light a color appears on a monochrome television screen or how much light the color reflects. It is also related to luminance.
