Problems solved by technology

In this case, even if the synthesis technique of the above-mentioned Patent Document 1 is applied, the generated data of a wide range of images cannot be accurately aligned with the feature points because the respective exposure values ​​of the plurality of images are different. Produces uneven brightness in connected parts of the image
Therefore, displaying a synthesized wide-range image may cause dissonance to viewers.

Abstract

An image capturing device includes an energy calculation unit, which calculates energy corresponding to each concerned pixel of the same image based on one image and other images forming a synthetic object of the image; an energy minimum path search unit, which searches a path of the image whose energy is the smallest among the calculated concerned pixel; a range search unit (55), which searches the pixel range of value similar to each concerned pixel; an alpha blend width determination unit, which determines the blend width of the one image and other images with the path being the starting point based on the searched pixel range, a transmittance setting unit, which sets the transmittance of the one image and other images at the time of synthesis based on the set blend width, and a combination unit which combines the one image and other images based on the blend width and the set transmittance.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method. Background technique [0002] As a prior art, Japanese Patent Laid-Open No. 11-282100 describes generating a panoramic image by synthesizing the data of a plurality of images in such a manner that the same feature points of a plurality of images taken continuously are aligned. technology for a wide range of image data. [0003] However, in general, it is difficult to completely match imaging conditions such as the influence of shadows, the timing of pressing the shutter button, and the timing of exposure of the imaging element among a plurality of images. Therefore, when data of a plurality of images is synthesized to generate data of a single wide-range image, the data of the synthesized image is affected by a difference in exposure value due to a difference in imaging conditions of the plurality of images. [0004] In addition, a plurality of images are capt...
