no. 1 Embodiment approach

[0072] figure 1 It is a block diagram showing an example of the hardware configuration of the imaging device of the embodiment. The imaging device 100 has functions of capturing images and processing the captured images. The imaging device 100 can be used, for example, as a mobile information terminal such as a video camera, a mobile phone or a smart phone with an imaging function, a PDA (Personal Digital Assistant, Personal Data Assistant, a personal digital assistant, a personal data assistant), a personal computer with an imaging function, or various It is implemented in the form of an embedded system built into an electronic device.

[0073] Such as figure 1 As shown, the imaging device 100 includes, for example, a filter 10 , a lens 20 , an image sensor 30 , an image processing unit, and a storage unit. The video processing unit is constituted by circuits such as CPU 40 , for example. The storage unit is composed of, for example, the RAM 50 and the nonvolatile memory ...

no. 2 Embodiment approach

[0177] As described above, the distance to the subject is calculated using the image captured by the imaging device, which is a monocular camera equipped with a color aperture. The color opening is configured by arranging a color filter having at least two color filter regions in the opening of the imaging device. The image sensor generates an image based on the light passing through the colored openings. exist figure 2 In the example shown, the first and second filter regions have a semicircular shape in which a circular filter is divided left and right (in the horizontal direction) by a line segment in the vertical direction passing through the optical center. For example, the first filter area is a yellow (Y) filter area, and the second filter area is a cyan (C) filter area. The light in the wavelength band of the green (G) image passes through the first and second filter areas, while the light in the wavelength band of the red (R) image only passes through the first fil...

no. 3 Embodiment approach

[0228] Figure 38 An installation example of the imaging device 502 of the third embodiment is shown. The third embodiment can also be applied to a monitoring system. In the second embodiment, an oblique downward image is taken from a ceiling, a wall, a pillar, etc., and a third embodiment in which an image directly below is taken from a ceiling will be described. That is, the optical axis of the imaging unit 505 is parallel to the vertical direction. The front end of a cylindrical arm 524 is fixed at the center of the rear end of the imaging device 502 . The axis of the arm 524 coincides with the optical axis of the imaging unit 505 or the imaging device 502 . The rear end of the arm 524 is inserted into the front end of the arm 526 which is concentric with the arm 524 and has a larger diameter than the arm 524 . Therefore, the arm 524 (and the imaging device 502 ) can be rotated clockwise and counterclockwise around the optical axis (also referred to as a roll axis) whil...

Abstract

The embodiment of the present invention relates to a processing apparatus, an imaging apparatus, an automatic control system, an imaging system, and a distance information acquisition method. The present invention provides a processing device, an imaging device, an automatic control system, an imaging system, and a distance information acquisition method capable of performing output and control relating to the reliability of a distance to a captured subject obtained from an image. According to an embodiment, a processing device includes an acquisition unit, a distance calculation unit, and a reliability calculation unit. The acquisition unit acquires a first image of the captured subject including the bokeh in a shape indicated by a symmetrical first point spread function and a second image of the captured subject including the bokeh in a shape indicated by the asymmetric second point spread function. The distance calculation unit calculates the distance to the captured subject based on the correlation between the first point spread function and the second point spread function. The reliability calculation unit calculates the reliability of the distance based on the degree of correlation.

Description

[0001] This application is based on Japanese patent application (2016-220642) (filing date: November 11, 2016) and Japanese patent application (2017-139402) (filing date: July 18, 2017), and enjoys priority from this application right. This application incorporates this application in its entirety by reference. technical field [0002] Embodiments of the present invention relate to a processing device, a camera device, an automatic control system, a camera system, and a distance information acquisition method. Background technique [0003] There is known a method of simultaneously acquiring captured images and distance information. [0004] However, output and control related to the reliability of the distance to the subject cannot be performed. Also, depending on the direction of the edges included in the subject, it may not be possible to obtain the distance to the subject. Contents of the invention [0005] An object of the present invention is to provide a processin...
