Kuvasignaalin

Kuvasignaalin is the genitive form of kuvasignaali, a Finnish noun meaning image signal. Kuvasignaali refers to the electrical or digital representation that conveys visual information, as used in video, photography, broadcasting, and related electronics. The term encompasses both analog and digital forms of signal that carry image data from a source to a display or processing device.

In Finnish technical language, kuvasignaalin is used to describe properties, processing, or characteristics of the image signal. Examples of common phrases include kuvasignaalin laatu (the quality of the image signal), kuvasignaalin taso (the level or strength of the image signal), kuvasignaalin latenssi or kuvasignaalin viive (the latency or delay of the image signal), and kuvasignaalin häiriöt (disturbances in the image signal). The term frequently appears in compound forms such as kuvasignaalin vahvistus, kuvasignaalin suodatus, or kuvasignaalin muuntaminen, reflecting stages in a signal chain.

The concept is central to the signal chain in video systems. A kuvasignaali is generated by a camera or other image sensor, transmitted through cables or networks, possibly converted or processed by an image processor, and finally delivered to a display or recording device. In modern contexts, kuvasignaali may be digital (for example, HDMI or SDI streams) or analog, depending on the equipment and standards in use. The term is widely used across electronics, broadcasting, film and video production, and surveillance industries.
