[0028] will refer to figure 1 Describing the general structure of the image pickup system 1 according to the first embodiment of the present invention, figure 1 is a diagram showing an exemplary structure of the image pickup system 1 .

[0029] An image pickup system 1 includes an image pickup device (camera body) 2, a mount adapter 10, and a lens (interchangeable lens) 7. The image pickup device 2 is a mirrorless digital SLR camera having reduced size and weight because the flange focal length of the mirrorless digital single lens reflex (SLR) camera is smaller than that of the digital SLR camera. camera subject. The lens 7 is an interchangeable lens used with a digital SLR camera, and may not be directly mountable on the image pickup device 2 because the desired flange distance of the lens 7 is different from that of the image pickup device 2 . Also, the lens 7 may not be mountable on the image pickup device 2 because the lens 7 has an interface different from that of the...

[0083] will refer to Figure 7 Describing the focusing process according to the second embodiment of the present invention, Figure 7 is a flowchart of the focusing process. When an image is to be picked up, the camera controller 100 performs focusing processing. The differences of the second embodiment from the first embodiment are as follows. According to the second embodiment, MA-AF or IMG-AF is set to have priority and MA-AF or IMG-AF is selected according to the priority, while according to the first embodiment, MA-AF or IMG is selected according to the focus detection condition -AF. In the detailed description of the second embodiment, the overall structure of the image pickup system according to the second embodiment is the same as that of the image pickup system according to the first embodiment unless otherwise noted.

[0084] In step S21, the camera controller 100 obtains a priority condition of MA-AF or IMG-AF. The priority condition description is set in advan...

[0093] will refer to Figure 8 Describing the focusing process according to the third embodiment of the present invention, Figure 8 is a flowchart of the focusing process. When an image is to be picked up, the camera controller 100 performs focusing processing. The third embodiment differs from the first embodiment in that the camera controller 100 receives a selection operation indicating which of MA-AF and IMG-AF is to be used for focusing. In the detailed description of the third embodiment, the overall structure of the image pickup system according to the third embodiment is the same as that of the image pickup system according to the first embodiment unless otherwise noted.

[0094]In step S31, the camera controller 100 determines whether MA-AF is selectable. Such determination can be performed by detecting the mounting adapter 10 mounted on the image pickup device 2 . The camera controller 100 can obtain identification information of the mount adapter 10 from the mo...

Abstract

The present invention relates to an image pickup system, an image pickup device, and a program. The image pickup system includes: an image pickup device; and a mount adapter that adjusts a flange distance between the image pickup device and the interchangeable lens. The mounting adapter includes: a phase difference focus detection unit capable of outputting a first phase difference focus detection signal; and an optical device that divides the first incident light into a second incident light and a third incident light. The first incident light is transmitted from the interchangeable lens. The second incident light enters the image pickup device. The third incident light enters the phase difference focus detection unit. The image pickup apparatus includes: an image pickup device capable of outputting a second phase difference focus detection signal; and a controller selecting one of the first phase difference focus detection signal and the second phase difference focus detection signal and performing focus adjustment on the basis of satisfying a predetermined condition.

Description

technical field [0001] The present invention relates to an image pickup system, an image pickup device, and a program. Background technique [0002] In recent years, the use of digital single-lens reflex (SLR) cameras has rapidly become common. However, the demand for smaller and lighter camera bodies for digital SLR cameras has not been met. It is considered that the camera body of a digital SLR camera will inevitably be large and heavy because such a camera body will include a mirror and a pentaprism. The mirror is used to switch between the light path for the camera and the light path for the viewfinder. A pentaprism is used to guide the subject image to the optical viewfinder (OVF). [0003] Mirrorless digital SLR cameras have been proposed. This mirrorless camera has no mirror because an electronic viewfinder (EVF) is used instead of an OVF, thereby realizing a small and light camera body. [0004] In addition to having no mirror, this mirrorless camera also has no...
