Title:
RANGE-FINDING DEVICE, IMAGING DEVICE, MOVEMENT DEVICE, ROBOT DEVICE, AND PROGRAM
Document Type and Number:
Japanese Patent JP2019174532
Kind Code:
A
Abstract:
To acquire images having high color reproducibility with a range-finding device, and to reduce errors of distance information.SOLUTION: A range-finding device 100 comprises: an imaging optical system 102 that has an optical filter 104; and an image pick-up element 103 that has a plurality of pixel parts arrayed. The optical filter 104 is segmented into three areas 104a to c, in which the first area 104a has a first spectroscopic transmission characteristic, and the second area 104b and the third area 104c have a second spectroscopic transmission characteristic that transmits light of a long wavelength in comparison to the first spectroscopic transmissive characteristic. The first pixel part constituting the image pick-up element 103 comprises a first photoelectric conversion unit, and is configured to receive light passing through the first area 104a. The second pixel part constituting the image pick-up element 103 comprises a second and a third photoelectric conversion units, and is configured to receive light passing through the second area 104b and the third area 104c, respectively. A distance information acquisition unit 105 is configured to acquire distance information corresponding to a parallax of image data based on each output signal of the second and the third photoelectric conversion units.SELECTED DRAWING: Figure 1
