Visual Perception Principles: Defining the Visual Field of the Television Screen
Pages 15

Any attempt to define the visual field of the television screen is futile unless the main theories, the organs, and the processes involved in visual perception are thoroughly defined and clearly understood. The physiology of the human perceptual organs, mostly the eyes, the ears, and the brain, and their specific functions are discussed in detail in Part II of this book. This chapter briefly examines only the basic anatomy of the eyes to explain how we perceive televised images. Specifically, this chapter introduces the following topics as they relate to the perception of television images: (a) basic approaches of perception, (b) visual stimulation (which includes also the visual sensory processes), (c) the perceptual process of television images, (d) the perception of elements within the visual field (which expands the discussion to include light and color), and (e) the perception of holographic and three-dimensional visual displays.
