Display system for motor vehicle passenger compartment, associated display method, and associated computer-readable medium

A display system for a passenger compartment of a motor vehicle, comprising a number N of activatable display surfaces, each display surface being activatable by a lighting control of at least one associated lighting unit, and a programmable electronic device configured to control a display on each display surface, the programmable electronic device comprising a processor, wherein the processor is configured to execute, at a given rate:

• a module for receiving a number P greater than 1 of digital images to be displayed at a given instant, said P digital images to be displayed being provided by at least two distinct sources;
• a module for combining the P digital images to be displayed at the given instant into a single full digital image, the combining comprising analyzing the P digital images to be displayed, and for each digital image to be displayed, determining a ratio of change of size and applying said ratio;
• in the case where the number N of activatable display surfaces is greater than 1, a module for dividing said full digital image into a number M less than or equal to N of digital sub-images to be displayed, each of the M digital sub-images to be displayed being intended to be displayed on a corresponding activatable display surface, and
• a module for controlling the display of each of the digital sub-images on the corresponding activatable display surface,
• wherein the module for dividing said full digital image into a number M less than or equal to N of digital sub-images is configured to implement a semantic image analysis to determine at least one low-entropy area, the dividing of the full digital image into M sub-images being carried out in said low-entropy area, and
• wherein the low-entropy area is defined by a number of contiguous pixels with fixed values or with values having a deviation less than a pre-defined threshold value between two successive images of a plurality of semantically analyzed consecutive images.
