Image acquisition device and image synthesis method thereof

Abstract

The invention discloses an image acquisition device and an image synthesis method thereof. The image acquisition device comprises an image acquisition module, an image synthesis module, a database and a processing module. The image acquisition module acquires a plurality of temporary images of a scene. The image synthesis module cuts out part of the temporary images so as to connect whole scene temporary images and divides a whole scene temporary image area into a plurality of areas according to at least one threshold and a whole scene luminance histogram of the whole scene temporary images. The database stores a lookup table so as to record a plurality of exposure values. The plurality of exposure values respectively correspond to the luminance value of every area. The processing module reads the plurality of exposure values corresponding to the luminance values, and weight exposure values are acquired by utilizing a relation expression so as to control the image acquisition module to perform whole scene image acquisition according to the weight exposure values.

Description

technical field [0001] The present invention relates to an image capture device and its image synthesis method, in particular to an image capture device and its image synthesis method for adjusting the weight of the exposure value of the scene. Background technique [0002] With the advent of the digital age and the continuous advancement of technology, digital cameras have become a must-have 3C product for almost everyone. During travel, people like to use cameras to record the beautiful scenery in front of them, but if they encounter a large area of ​​beautiful scenery, they may not be able to completely record the beautiful scenery in front of them; It is also difficult to achieve a complete record of the scene from the angle. Therefore, a panorama interface is developed to accomplish the above-mentioned purpose. [0003] When some users perform panorama splicing, they expose and shoot each angle of the scene separately, and then splice the multiple images that have bee...
