Realization method for grading photos of digital camera

Abstract

The invention discloses a realization method capable of grading photos taken by a digital camera and providing technical direction according to score value. The method comprises two parts of a photo parameter extraction system and a grading system. The realization method comprises the following steps that: after the photo grading function is started, the camera automatically applies the parameter extraction system to extract parameters such as the f number, the shutter speed, the white balance, the exposure, the ISO value and the like of a photo when a user takes the photo, compares the extracted parameters with preset standards, grades the extracted parameters, sums up the overall scores according to the weight of various parameters, and outputs the overall scores on an LCD screen, so that the user can look over the scores of various parameters in real time and can adjust and set related camera parameters again according to the graded scores so as to achieve the aim of obtaining better effect when the user takes a photo for next time.

Description

Technical field [0001] The invention relates to the field of digital cameras, and more specifically, to a method for realizing scoring of photos taken by a household digital camera. Background technique [0002] Currently, there is no camera in the digital camera market that can score photos taken and guide users based on the scores. Most digital cameras can prompt the focus status when taking pictures, but cannot provide users with clearer guidance. And for the selection of shutter and aperture, most users still adopt the method of automatic camera selection. They are less able to adjust the aperture, shutter size and exposure mode according to different scenes. They do not have a good grasp of the degree of exposure and cannot be carried out through timely guidance. Adjust in time. [0003] Regarding white balance and metering methods, the mainstream digital cameras in the world generally have a variety of built-in white balance and metering methods, but users are often not sur...

Problems solved by technology

Most digital cameras can prompt the focus status when taking pictures, but cannot provide clearer guidance to users

And for the selection of shutter and aperture, most users still use the automatic selection method of the camera, and seldom can adjust the aperture, shutter size and exposure mode according to different scenes. Adjust in time

[0003] Regarding the white balance and light metering methods, the mainstream digital cameras in the world generally have a variety of built-in white balance and light metering methods, but users are often not sure which one to use under what conditions, and it is difficult to accurately select the ISO value. proper value
