What does the image mean?

Image is the material representation of human visual perception.

Images can be obtained by optical devices, such as cameras, mirrors, telescopes and microscopes. It can also be created manually, such as hand-drawn images. Images can be recorded and stored in paper media, films and other media sensitive to optical signals.

Through professionally designed images, we can develop the visual language for adults to communicate with each other, and we can also understand a large number of plane paintings, three-dimensional sculptures and buildings in world art.

Images are also called images. Refers to the imaging mode of non-photographic imaging sensor, and its essence is the extension of photographic photos. Photograph usually refers to optical photography imaging and recording on photosensitive film, which is passive remote sensing imaging.

Images can receive visible light, infrared, thermal infrared and microwave information of ground objects through optical machine, photoelectric or antenna scanning, and be recorded on magnetic tape or photosensitive film through photoelectric conversion.

Compared with photos, it has a wider scope in content and form. Using "images" to include (rather than replace) "photos" is the result of the development of aerial reconnaissance to remote sensing and photography to imaging.

Image is the part of audio-visual language that appeals to "seeing" and is the basis of audio-visual language. First of all, the basic unit of an image is "shot", which is not the smallest division unit of film and television language, but it is the basic unit that is convenient for research and analysis. Strictly speaking, there is no minimum segmentation unit in a certain linguistic sense in film and television language.
