输入人物图片

【任务目标】

请将提供的照片处理成一张符合官方规范的标准证件照。核心要求是：在满足证件照严谨性的前提下，进行适度、自然的美化，确保人物精神饱满且能准确识别为本人（严禁过度美化至失真）。

【智能美化与修饰】（根据人物特征自适应）

面部轮廓与五官： 适度优化面部轮廓线条，使其更加端正、对称。增强五官的立体感，但需保持人物原有的骨相特征。

皮肤处理（分年龄段处理）：

均匀肤色，去除明显的瑕疵（如痘印、斑点、红血丝）。

改善眼袋和黑眼圈，提升眼部神采。

关键： 保持皮肤自然的质感。对于中老年人，请保留符合年龄的自然皱纹和岁月痕迹，切勿过度磨皮导致面部僵硬。

毛发整理（男女通用）：

发型： 将原有发型整理得整洁、干练、服帖。去除杂乱的碎发和飞发。

胡须（针对男性）： 如果有胡须，请将其修剪得整齐干净；如果原照片无胡须或胡须杂乱，请处理为剃净后的清爽状态。

妆容调整： 如原照片有妆容，请减淡为符合证件照要求的清新裸妆或无妆感，避免浓妆艳抹。

【证件照硬性规范】

背景颜色： 替换为纯正的证件照蓝色背景（色值均匀，无渐变）。

输出规格：

尺寸：480px（宽）× 640px（高）。

格式：JPG。

文件大小：严格控制在 20KB - 40KB 之间。

构图要求：

人像绝对居中。

脸部宽度需适中，左右两侧背景留白均不少于80像素。

眼睛位置线应处于照片整体高度上部约 55% 处（参考A4打印纸构图线）。

【姿态与表情校正】

姿态： 调整为标准的正面直视镜头，确保双肩平衡、对称，头部端正。

表情： 表情自然、平和，嘴唇自然闭合（不露齿），目光平视前方。

【配饰与遮挡处理】

眼镜：

如有佩戴眼镜，首选移除。

若必须保留，请确保镜片无任何反光，且镜框不遮挡眼睛轮廓；如有彩色/美瞳隐形眼镜，请替换为透明。

饰品： 移除所有可见的耳环、项链、头饰等饰品。

五官露出： 确保头发不遮挡眉毛、眼睛和双耳（耳朵需对称可见）。

【衣着优化】

色彩调整： 如果原衣物颜色与蓝色背景过于接近（导致融合），请将其调整为能与背景形成对比的深色系（如深灰、深黑）。

款式简化： 抚平衣服褶皱，简化衣服上过于花哨复杂的图案、条纹或Logo，使其显得庄重。

[Task Objective] Please process the provided photo into a standard ID photo that complies with official specifications. Core requirement: While meeting the strict requirements of an ID photo, perform moderate and natural enhancement, ensuring the person looks spirited and can be accurately identified as themselves (strictly prohibit excessive enhancement to the point of distortion). [Smart Enhancement and Retouching] (Adaptive based on individual features) Facial contour and features: Moderately optimize facial contour lines to make them more symmetrical and well-proportioned. Enhance the three-dimensionality of facial features, but maintain the person's original bone structure characteristics. Skin treatment (different approaches for different age groups): Even out skin tone, remove obvious imperfections (such as acne marks, spots, red blood vessels). Improve dark circles and bags under the eyes, enhance eye vitality. Key: Maintain natural skin texture. For middle-aged and elderly people, please retain natural wrinkles and signs of age appropriate to their age, do not over-smooth the skin to cause facial stiffness. Hair grooming (for both men and women): Hairstyle: Neaten the existing hairstyle to be tidy, capable, and smooth. Remove messy flyaway hairs and stray hairs. Beard (for men): If there is a beard, trim it neatly and cleanly; if the original photo has no beard or a messy beard, process it to a clean-shaven state. Makeup adjustment: If the original photo has makeup, please lighten it to a fresh natural makeup or no-makeup look suitable for ID photos, avoid heavy makeup. [ID Photo Hard Specifications] Background color: Replace with a pure ID photo blue background (uniform color value, no gradient). Output specifications: Size: 480px (width) × 640px (height). Format: JPG. File size: Strictly controlled between 20KB - 40KB. Composition requirements: Portrait must be absolutely centered. Face width should be appropriate, with at least 80 pixels of blank space on both sides of the background. The eye position line should be at approximately 55% from the top of the photo's overall height (refer to A4 paper composition lines). [Posture and Expression Correction] Posture: Adjust to standard frontal view facing the camera, ensuring balanced and symmetrical shoulders, upright head. Expression: Natural and calm, lips naturally closed (no teeth showing), gaze looking straight ahead. [Accessory and Obstruction Handling] Glasses: If worn, preferably remove. If must be kept, ensure no reflections on the lenses, and the frames do not obstruct the eye contours; if there are colored/colored contact lenses, replace with transparent. Accessories: Remove all visible earrings, necklaces, headwear, etc. Facial features exposed: Ensure hair does not cover eyebrows, eyes, and both ears (ears must be symmetrically visible). [Clothing Optimization] Color adjustment: If the original clothing color is too close to the blue background (causing fusion), adjust it to a dark color that contrasts with the background (such as dark gray, dark black). Style simplification: Smooth out clothing wrinkles, simplify overly fancy patterns, stripes, or logos on clothing to make them appear dignified.
