An image generating apparatus is provided with a first light source and a second light source, an image sensor, a mask including a light-transmitting part and a light-blocking part, and a dark image processing unit. The image sensor acquires a first image of the material when illuminated by the first light source, and acquires a second image of the material when illuminated by the second light source. The image sensor includes a first pixel region and a second pixel region. The light-blocking part is positioned between the first pixel region and the first light source. The light-blocking part is positioned between the first pixel region and the first light source. The dark image processing unit uses first pixel information corresponding to a first pixel region in the first image and second pixel information corresponding to a second pixel region in the second image to generate a third image.

Image generating apparatus and image generating method

An image generation apparatus includes first and second light sources, an image sensor, a mask, and a processing circuit. The image sensor acquires a first image when the first light source is energized and acquires a second image when the second light source is energized. The processing circuit obtains a pixel value based on a direct light component or a pixel value based on a component other than the direct light component corresponding to a focal point by using pixel values of first pixel regions of the first image, pixel values of second pixel regions of the second image, the ratios of the direct light and the light other than the direct light from the first light source, and the ratios of the direct light and the light other than the direct light from the second light source and generates a cross-sectional image of a substance on the focal plane.
