  • Patent number: 10206566
    Abstract: Disclosed embodiments may include a device, system and method for providing a low cost device that can measure refractive errors very accurately via attachment to a smart phone. A disclosed device may use ambient light or a light source in simulating the cross cylinder procedure that optometrists use by utilizing the inverse Shack-Hartman technique. The optical device may include an array of lenslets and pinholes that will force the user to effectively focus at different depths. Using an optical device, in conjunction with a smart phone, the user first changes the angle of the axis until he/she sees a cross pattern (the vertical and horizontal lines are equally spaced). The user adjusts the display, typically using the controls on the smartphone, to make the lines come together and overlap, which corresponds to bringing the view into sharp focus, thus determining the appropriate optical prescription for the user.

  • Patent number: 9264624
    Abstract: An image obtained by superimposing the image of the subject, which is displayed on the display screen of an electronic viewfinder, upon the optical image of the subject can be seen by the user looking through a finder unit. Display position on the display screen of the electronic viewfinder is shifted so as to correct for parallax between the finder unit and the solid-state electronic image sensing device. When the image of the subject is in focus, the optical image of the subject and the electronically captured image of the subject coincide. When the image of the subject is not in focus, the optical image and the electronically captured image are offset from each other. Correct focus can be achieved while observing the extent of offset between these images of the subject through the finder unit.

  • Patent number: 8836847
    Abstract: A method for capturing an image, comprising: providing a switchable imaging apparatus including a display screen having a first display state and a second transparent state, an optical beam deflector switchable between a first non-deflecting state and a second deflecting state, a camera positioned in a location peripheral to the display screen, and a controller; setting the switchable imaging apparatus to the image capture mode by using the controller to set the display screen to the second transparent state and the optical beam deflector to the second deflecting state; using the camera to capture an image of the scene; setting the switchable imaging apparatus to the image display mode by using the controller to set the display screen to the first display state and the optical beam deflector to the first non-deflecting state; and displaying an image on the display screen.

    Abstract: A method of providing an on screen display (OSD) in a mobile communication terminal using a Q-camera includes: entering into a viewfinder mode, and receiving image data inputted from a camera sensor as image data of the viewfinder mode when an operation mode of the mobile communication terminal switches into a camera mode; if an OSD menu is set, merging an OSD image corresponding to a setting value of the OSD menu with the image data of the viewfinder mode, and then updating a display screen of the mobile communication terminal with the merged data; and encoding the image data of the viewfinder mode to perform the photographing if there is a request for photographing. The actually changed OSD image is selectively employed to merge with the image data of the viewfinder mode to update the display screen, and thereby a partial OSD function can be realized.

  • Publication number: 20140226055
    Abstract: A collapsible viewing device for a camera LCD screen includes a base having an open camera end that is sized to fit around an associated camera display screen. An eyepiece opposite the base allows for viewing an image on the associated camera display screen. A flexible, light-blocking sidewall extends between the base and the eyepiece. The viewing device is configurable between an expanded use disposition in which the eyepiece is spaced from the base and a collapsed, compact disposition in which the sidewall is non-hingedly collapsed into the base.

  • Publication number: 20140211068
    Abstract: A camera 10 has an imaging optical system, an imaging device 21a, and a finder device 15. The finder device 15 includes a variable magnification lens 64 which can be inserted into and removed from an optical path, and a shutter 62 which can switch between a closed state in which it interrupts light coming from a finder window 16 and an open state in which it allows passage of light coming from the finder window 16. The camera 10 is equipped with a driver 54 for controlling insertion and removal of the variable magnification lens 64 in accordance with the focal length of the imaging optical system, a driver 53 for controlling the state of the shutter 62, and a CPU 82. The CPU 82 controls the shutter 62 so that it is kept in the closed state while the variable magnification lens 64 is being moved.

    Abstract: An image capturing apparatus and an image processing method are disclosed. The image capturing apparatus includes an image capturing module, a micro processor, and a display module. The image capturing module continuously captures images corresponding to different focus distances. The display module displays an initial display image of the images. The micro processor divides the initial display image into a plurality of lattice areas and uses one of the plurality of lattice areas as a specific lattice area. The micro processor compare sharpness values of areas corresponding to the specific lattice area in the plurality of images corresponding to the different focus distances to generate a comparison result and selects a first image from the plurality of images according to the comparison result. The display module displays the first image to replace the initial display image previously displayed.
