Unverified分辨率标称与实际有差距，认准1080P（200万像素）以上并关注传感器而非插值像素，很多低价机标称高像素实为软件插值，实际画质模糊79% similarUnverified扫描分辨率日常文档600dpi足够，翻拍老照片或需要放大打印才需1200dpi光学分辨率——注意区分光学分辨率和插值分辨率，后者是软件算法放大无实际意义79% similarUnverified2420万像素属于中等分辨率，追求高像素大幅裁切或商业风光大图输出的用户建议看更高像素机型78% similarUnverified分辨率优先看PPI而非总像素，300PPI是文字锐利的分水岭，低于212PPI的机型近距离可见颗粒感，选购时用屏幕像素除以对角线尺寸换算验证78% similarUnverified分辨率优先看清晰度而非单纯像素，2K(2560×1920)且带HDR宽动态才能在逆光门口看清快递单和人脸；仅1080p在强光背景下人脸易过曝78% similar
