Summary:In the modern world, image transmission, including transmission of television and video signals, is carried out using a preliminary and restorative correction according to the law, which was due to the use of imaging devices on cathode ray tubes. This law differs from the law of dependence of the visibility threshold of a visual stimulus on its magnitude, but continues to be used for compatibility reasons. Therefore, in the work, instead of linearizing the sensations of the quantization scale of a television signal, it is proposed to optimize the choice of code combinations for image transmission. This approach can be effective in television systems without compression of video information with losses, for example, for transmitting signals over short distances or in channels for transmitting signals of the image of Earth remote sensing systems
