AIによるテキスト削除の仕組み
Text on a photo is rarely just a flat sticker — it sits on top of skies, faces, brick walls, menus, and signage, and each letter hides a slightly different patch of background. Removing it cleanly means rebuilding what every stroke and serif was covering, then matching the colour, lighting, and texture of the surrounding area. Done by hand with a clone stamp, that is slow and usually leaves smears or repeated patterns. Magic Eraser handles it in one pass: you mark the words — a meme caption across the top, a watermark-style line of credit text, a street sign, a product label, or subtitles baked into a screenshot — and the AI paints them out and fills the gap with a plausible continuation of the background. The result depends heavily on what the text was sitting on, which is the honest part most tools skip over.

注意事項
Text removal is only as good as the background under the letters, and Magic Eraser is candid about that. Words sitting on a plain, even surface — a clear sky, a solid wall, a blurred backdrop, flat-colour packaging — reconstruct almost invisibly, because the AI only has to extend a simple, predictable texture. Words sitting on detailed or unique content are different: text laid over a person's face, dense text, fine print over a patterned fabric, or a sign whose underlying shopfront is fully hidden cannot be recovered, because that information genuinely is not in the image. There the AI estimates a plausible fill rather than restoring the true pixels, so treat the patch as a believable reconstruction, not a reveal of what was actually behind the words. For best results, brush tightly around each character, include outlines and shadows, and run a second pass on any ghosting. Note this is distinct from a semi-transparent watermark or a graphic logo — here you are removing readable, opaque lettering, which the AI can isolate cleanly but must rebuild from scratch underneath.
