Device and method for compensating exchangeable image file information of digital image

Abstract

The invention relates to a device and a method for compensating exchangeable image file information of a digital image. The device comprises an acceleration sensor, a magnetic sensor, an exchangeable image file information storage element and an image processing chip, wherein the image processing chip is respectively connected with the acceleration sensor, the magnetic sensor and the exchangeable image file information storage element; the acceleration sensor and the magnetic sensor are used for detecting an angle of a photographing equipment body relative to the horizontal plane, an angle of a camera lens relative to the horizontal plane and an azimuth angle of the photographing equipment body or the camera lens relative to the arctic pole of the earth during photographing digital images by photographing equipment using the acceleration sensor and the magnetic sensor; the image processing chip is used for receiving and processing angle and azimuth information; and the exchangeable image file information storage element is used for storing digital image files written with character strings in a labeled data form, wherein the character strings stand for the corresponding angle and azimuth information and are processed by the image processing chip. Shutterbugs and professional photographers can effectively improve photography technique based on the angle and azimuth information acquired by the method and the device.

Description

technical field [0001] The present invention relates to a device and method for supplementing exchangeable image file information of a digital image, in particular to a device and method for supplementing exchangeable image file information of a digital image captured by an imaging device (for example, a digital camera). Background technique [0002] In a digital camera, when a photo is taken and saved as a JPG or TIFF format, some information will be stored in each image file in the form of an Exchangeable Image File (EXIF, Exchangeable Image File) Tag. EXIF Tag information is a series of information collected by the digital camera during the shooting process, and then put the information at the head of the JPG or TIFF file we know well, that is to say, the EXIF ​​Tag information is embedded in the JPG or TIFF image file format A set of shooting parameters. [0003] Among them, the orientation tag is usually only used to determine whether the camera is in a horizontal or v...
