Abstract: According to various examples, a first resolution of original display data and a second resolution of a text display may be obtained. In response to a determination that the second resolution is smaller than the first resolution, the original display data may be searched for a relocation area and a bland area. The relocation area may include valid pixels not capable of being displayed on the text display. The blank area may not include valid pixels and may be capable of being displayed on the text display. The blank area may be used to accommodate the relocation area within the text display to generate reconstructed display data, and the reconstructed display data may be outputted to the text display.
