The copyright rules around AI-generated images are still evolving, but generally, it's considered that AI-generated images can be copyrighted if they meet certain criteria. According to the US Copyright Office, for a work generated by AI to be eligible for copyright protection, it must be a creative expression that is sufficiently original. This means that the AI-generated image must have a level of creativity and originality that goes beyond a simple application of a formula or algorithm. Additionally, the image must be fixed in a tangible form, such as being saved as a digital file or printed on paper.
However, it's important to note that copyright protection for AI-generated images is not automatic. The creator of the AI-generated image must take steps to register the work with the Copyright Office in order to establish legal protection. Additionally, the use of AI-generated images raises other legal questions, such as whether the use of an AI-generated image without permission could be considered copyright infringement. Ultimately, the use of AI-generated images is a complex legal issue that requires careful consideration of the specific circumstances and applicable laws.
