如何在python中更改图像捕获日期？

Question

由于相机日期设置错误，我有超过 500 张图像 (png /jpg) 的拍摄日期（拍摄日期）错误。我将照片移动到手机，手机图库根据“拍摄日期”对照片进行分类。我希望所有照片都按顺序显示。

那么如何使用 python 脚本更改捕获日期（拍摄日期）？

Answer 1

使用piexif 库很容易做到这一点：

from datetime import datetime
import piexif

filename = 'image.jpg'
exif_dict = piexif.load(filename)
new_date = datetime(2018, 1, 1, 0, 0, 0).strftime("%Y:%m:%d %H:%M:%S")
exif_dict['0th'][piexif.ImageIFD.DateTime] = new_date
exif_dict['Exif'][piexif.ExifIFD.DateTimeOriginal] = new_date
exif_dict['Exif'][piexif.ExifIFD.DateTimeDigitized] = new_date
exif_bytes = piexif.dump(exif_dict)
piexif.insert(exif_bytes, filename)

此脚本会将新日期2018:01:01 00:00:00 插入image.jpg 的DateTime、DateTimeOriginal 和DateTimeDigitized EXIF 字段。

Answer 2

不需要编写 Python，您可以在终端中使用 jhead 一行代码完成。例如，将所有 EXIF 时间向前调整 1 小时

jhead -ta+1:00 *.jpg

复制您的文件并首先对其进行测试！

我可能会迟到，但我编写了一个 python 脚本，用于根据文件名格式批量更改 whatsapp 照片的拍摄时间字段，例如：IMG-20160117-WA0001.jpg。 这也不会覆盖现有属性。 https://github.com/dsouzawilbur/Scripts/blob/master/Change_Photo_Taken_Time.py

            fullPath = os.path.abspath(os.path.join(dirpath, f))
            if re.match(r"^IMG-\d\d\d\d\d\d\d\d-WA\d\d\d\d.*", f) and not re.match(r"^IMG-\d\d\d\d\d\d\d\d-WA\d\d\d\d-ANIMATION.gif", f):
                print(f+" Matched")

                #Update DateTimeOriginal
                exif_dict['Exif'][piexif.ExifIFD.DateTimeOriginal] = datetime(int(year), int(month), int(day), 4, 0, 0).strftime("%Y:%m:%d %H:%M:%S")

                exif_dict['Exif'][piexif.ExifIFD.DateTimeDigitized] = datetime(int(year), int(month), int(day), 4, 0, 0).strftime("%Y:%m:%d %H:%M:%S")

PNG 不支持 EXIF，所以我根据Wilbur Dsouza 的answer 来修复创建/修改时间：

import datetime
import os
import re
import sys
import time

import piexif


def fix(directory):
    print(directory)
    for dirpath, _, filenames in os.walk(directory):
        for f in filenames:
            fullPath = os.path.abspath(os.path.join(dirpath, f))
            # Format: Screenshot_20170204-200801.png
            if re.match(r"^Screenshot_\d\d\d\d\d\d\d\d-\d\d\d\d\d\d.*", f):
                match = re.search("^Screenshot_(\d\d\d\d)(\d\d)(\d\d)-(\d\d)(\d\d)(\d\d).*", f)
                year = int(match.group(1))
                month = int(match.group(2))
                day = int(match.group(3))
                hour = int(match.group(4))
                minute = int(match.group(5))
                second = int(match.group(6))

                date = datetime.datetime(year=year, month=month, day=day, hour=hour, minute=minute, second=second)
                modTime = time.mktime(date.timetuple())

                print(f, date)

                os.utime(fullPath, (modTime, modTime))


if __name__ == "__main__":
    fix(sys.argv[1])
