  • Patent number: 11614822
    Abstract: Provided is an imaging device that includes a rear display and an electronic viewfinder and is excellent in operability to a touch panel when an electronic viewfinder is used. When a user performs a touch manipulation on a touch panel installed in a rear display in order to set a focus area, an effective detection area for detecting a touch position is different between when the rear display is used and when the electronic viewfinder is used. When the rear display is used, the effective detection area is set to coincide with the entire display screen, and when the electronic viewfinder is used, the effective detection area is set to be reduced to an area of a part of the display screen of the rear display.

  • Patent number: 11606548
    Abstract: An external scene image captured by an external scene imaging electronic camera attached to a head mounted display (HMD) is projected and displayed onto an image display screen arranged in front of the eyes of the user as a virtual image with a suitable viewing distance corresponding to the visual acuity of the user. At this time, for each object image presented in the virtual image of the external scene image, the virtual image is processed and formatted to add a predetermined degree of binocular disparity and image blur to the virtual image projected and displayed on the right and the left image display screen on the basis of a predetermined converted distance calculated from the real distance of each object. Thus, the user is given a sense of a realistic perspective for the virtual image of the external scene, free of the discomfort or unease.
