Abstract: A range-information acquiring apparatus includes a light source, an image sensor, a control circuit, and a signal processing circuit. The control circuit causes the light source to emit first light toward a scene and subsequently emit second light toward the scene, the first light having a first spatial distribution, the second light having a second spatial distribution. The control circuit causes at least a portion of plural photodetector elements of the photodetector device to detect first reflected light and second reflected light in the same exposure period, the first reflected light being caused by reflection of the first light from the scene, the second reflected light being caused by reflection of the second light from the scene. The signal processing circuit generates range data based on photodetection data output from the photodetector elements of the photodetector device.

Abstract: An image generating apparatus is provided with: first and second light sources that illuminate a material; an image sensor on which the material is disposed; a mask which includes a light-transmitting part that transmits light and a light-blocking part that blocks light, and which is positioned between the image sensor and the first and second light sources; and a light and dark image processing unit. The image sensor acquires first and second images of the material when illuminated by the first and second light sources, respectively. The light and dark image processing unit derives a difference between a luminance value of a pixel included in the first image and a luminance value of a pixel included in the second image at the same position as the pixel included in the first image, and thereby generates a third image of the material.

Abstract: An image acquisition device according to the present disclosure includes a lighting system and an irradiation direction decision section. In a module, a subject and an imaging element are integrally formed. The lighting system sequentially irradiates the subject with illumination light in a plurality of different irradiation directions based on the subject such that the illumination light transmitted through the subject is incident on the imaging element. The module acquires a plurality of images according to the plurality of different irradiation directions. Before the plurality of images are acquired according to the plurality of different irradiation directions, the irradiation direction decision section decides the plurality of different irradiation directions based on a difference between a first preliminary image and a second preliminary image. The first preliminary image is acquired when the subject is irradiated with first illumination light in a first irradiation direction, and the second preliminary image is acquired when the subject is irradiated with second illumination light in a second irradiation direction.
