Abstract:
1. An image synthesis device that generates a synthetic image by synthesizing a first image and a second image of a longer exposure time than the first image, the image synthesis device comprising: a first pixel selection unit which sets a first filter area around a pixel of interest on the first image, and which selects, from the first filter area, a first pixel having a value within a first allowable range which includes a value of the pixel of interest and is set based on the value of the pixel of interest; a second pixel selection unit which sets a second filter area around a reference pixel that is located on the second image in a same position as the pixel of interest, and which selects, from the second filter area, a second pixel having a value within a second allowable range which includes the value of the pixel of interest on the first image and is set based on the value of the pixel of interest in the first image; and a synthesis unit which sets a synthetic value, acquired by synthesizing the value of the first pixel and the value of the second pixel, as a value of a pixel located on the synthetic image in the same position as the pixel of interest.
