Visual Perception and Image Analysis in Mass Media
1. Visual Perception and Image Analysis
1.1 The Impact of Television
The emergence of television in the 1940s transformed mass media and the way people think. Advertising utilizes television’s visual power to capture attention and create needs.
The image, as defined by Moles, is a visual communication tool that materializes a fragment of the surrounding environment and forms a crucial component of mass media. Initially perceived as a means to reproduce reality, photography’s artistic potential and its role in advertising were later recognized.
1.2 Interpreting Images
Several factors influence image interpretation:
- Tangible elements like objects and colors
- Personal experiences and knowledge
- The information being sought
- Physical and psychological state
- Visual culture
- The medium (film, television, radio)
- Target audience demographics
- Sensations and inferences
1.3 Image Characteristics
- Level of Figuration: Representation of objects or beings with accuracy.
- Iconicity: The degree to which an image is simplified and schematized.
- Abstraction: The level of unreality.
- Complexity: Determined by the arrangement and composition of the image.
- Optical Noise: Elements that hinder image perception.
- Aesthetics: The overall visual appeal of the image.
- Normalization: Adherence to cultural and audiovisual design norms.
2. Image Representation and Essential Elements
2.1 Image Creation in the Brain
Eye movements and intelligence influence image creation:
- Micromovements: Unconscious movements to maintain the image on the retina.
- Saccades: Movements that ensure image perception.
- Intelligence and Perception: Creating associations and meaning.
- Fixation: The act of focusing on a specific point.
2.2 Visual Illusions
Visual illusions are distortions in perception caused by physiological or cognitive factors. Examples include:
- Geometric illusions: Distortions in size or shape, such as the Müller-Lyer illusion.
- Ponzo illusion: Perception influenced by surrounding context.
- Poggendorff illusion: Misalignment perception due to surrounding lines.
2.3 Gestalt Principles
Gestalt psychology explores how the brain perceives and organizes visual information. Key principles include:
- Figure-ground: Distinguishing objects from their background.
- Proximity: Grouping nearby elements together.
- Similarity: Grouping similar elements together.
- Closure: Perceiving incomplete figures as whole.
- Good continuation: Following lines or curves that flow smoothly.
- Common fate: Grouping elements moving in the same direction.
- Experience: Interpreting images based on past experiences.
2.4 Compositional Elements
Various elements contribute to image composition:
- Color: Evokes emotions and influences perception.
- Form: Creates shapes and defines objects.
- Movement: Implied or actual motion within the image.
- Texture: Visual or tactile surface quality.
- Meaning: The overall message conveyed by the image.
2.5 Observing Images: The Rule of Thirds
The rule of thirds divides an image into nine equal parts, with points of interest placed at the intersections. Viewers typically scan images clockwise, starting from the top left.

2.8 Representative Positioning Strategies
Brands may adopt unique positioning strategies based on factors like quality, quantity, price, or consumer psychology.
2.9 Morphological Elements
Morphological elements like points, lines, planes, textures, and forms create spatial dimensions and evoke emotions.
2.10 Movement, Tension, and Rhythm
Morphological elements can be used to create movement, tension, and rhythm within an image.
2.11 Structure and Scale
Structural elements like dimension, ratio, format, and scale define the proportions and size of objects within an image.
