Image processing devices, electronic device and image processing methods

An image processing device, comprising:

• interface circuitry configured to receive first image data representing a first image exhibiting a first aspect ratio smaller than one, wherein the first image is a photograph or a still frame of a recorded video depicting a scene, and wherein the first image data comprise metadata indicative of a respective class, a respective size and a respective position of one or more object in a surrounding of the scene not depicted in the first image;
• and
• processing circuitry configured to generate second image data representing a second image exhibiting a second aspect ratio greater than one, wherein, for generating the second image data, the processing circuitry is configured to:
• add a first image area and a second image area to the first image at opposite lateral sides of the first image;
• extend a background in the first image into the first and the second image area;
• identify at least one foreground object in the first image;
• determine whether the foreground object is complete in the first image;
• if it is determined that the foreground object is not complete in the first image, determine a visual representation of a missing part of the foreground object and arrange the visual representation of the missing part into one of the first image area and the second image area to complete the foreground object;
• determine a respective visual representation of the one or more object in the surrounding based on the respective class and the respective size of the one or more object indicated by the metadata;
• and
• add the respective visual representation of the one or more object in the surrounding into a respective one of the first image area and the second image area based on the respective position of the one or more object indicated by the metadata.
