Problems solved by technology

In practice, therefore, the computing power and available memory are often limited
The use of additional external memory is often disadvantageous, because the memory itself not only causes costs, but also significantly increases the complexity of the "embedded system", or in terms of the certification necessary for automotive applications on the market is not available

Abstract

The invention relates to a vehicle headlight (1) comprising a light source (2), a primary optical system (3), a projection optical system (4), a control device, an output unit and an optoelectronic component (7) having a controllable arrangement of several, individually adjustable optoelectronic elements (8) in the form of a two-dimensional matrix. Said vehicle headlight (1) is designed to emit light from at least one light source (2) in the direction of the optoelectronic component (7) and to modulate by means of the optoelectronic component (7), and to radiate at least partially in the direction of the projection optical system (4) and to form a light image in front of the vehicle. The control device is connected to the output unit. The output unit is connected to the optoelectronic component (7) and can control the optoelectronic elements (8). A light model is stored in the control device in the form of a plurality of protection points, and the control device is designed to form, from the light model, image data in the form of a two-dimensional matrix-shaped situation light distribution with a situational image resolution. The situational image resolution is essentially higher than the plurality of protective points of the light model. The image data is formed, preferably by interpolation from the protective points and can be represented on the optoelectronic component (7) by means of the output unit.
