  • Patent number: 9626782
    Abstract: This invention can develop a part of RAW image data and display the developed part of RAW image data with a result of processing, even if the part of the RAW image data refers to other part of the RAW image data. An image processing apparatus obtains an output area of RAW image data to be displayed on a window and a reference area of RAW image data to be pasted to the output area of the RAW image data. The apparatus develops the output area of the RAW image data and the reference area of the RAW image data. Then, the apparatus pastes a development result of the reference area of the RAW image data on a development result of the output area of the RAW image data.

  • Patent number: 9628694
    Abstract: An image pickup apparatus that performs focusing and zooming by driving lenses and enables focusing that reduces variations in the angle of view without making any modifications to an optical system. An image pickup optical system has a first lens that changes the shooting angle of view, and a second lens that changes a focus position for a subject. An image of the subject formed by the image pickup optical system is converted into an electric signal. The first lens and the second lens are driven. The amount of wobble for use in controlling the focus position for the subject is set according to drive characteristics of at least one of the first lens and the second lens.

  • Patent number: 9491365
    Abstract: A system embodiment may include at least one camera wearable, at least in part, by a human operator. The at least one camera may have, when enabled, at least one active field of view that may be captured by the at least one camera in response, at least in part, to image capture actuation by the human operator. This embodiment also may include a viewfinder wearable, at least in part, on a head of the human operator. The viewfinder may provide to the human operator, prior to the image capture actuation, at least one visual indication of the at least one active field of view of the at least one camera. The at least one visual indication may be displayed in at least one central field of vision of the human operator. Of course, many alternatives, modifications, and variations are possible without departing from this embodiment.

  • Patent number: 9459825
    Abstract: Systems and methods are provided for viewing portions of a very high-resolution image on a client device. The systems and methods provide for dynamic establishment of hierarchically organized contexts corresponding to regions within the image. The context hierarchy supports image inspection and analysis at increasing resolution levels for successively smaller regions. A context's region can be viewed at a base resolution appropriate for that context, while areas of interest within the context can be examined in more detail in higher resolution. To view areas of interest at resolution levels above the range for a given context, a child context can be established for a smaller region. The client device user can navigate from one area within the image to another by traversing previously established contexts and establishing new contexts.

    Abstract: A variable-magnification optical system has five lens groups, namely, from object side, positive, negative, positive, positive, and negative lens groups, and achieves magnification variation by varying all axial distances between the lens groups. Focusing is achieved by moving the fourth lens group in optical axis direction. Vibration correction is achieved by moving all or part of the fifth lens group perpendicularly to optical axis. Fulfilled are formulae 4.0<|f1/f2|<6.0, 1.0<f4/f1<1.5, and 2.0<|f4/fv|<4.0, f1 representing a focal length of the first lens group, f2 a focal length of the second lens group, f4 a focal length of the fourth lens group, and fv a focal length of the vibration correction group.

  • Patent number: 9380201
    Abstract: When a first instruction operation is performed by a user, a controller changes a zoom position in a wide-angle direction. When a second instruction operation is performed by the user, the controller changes the zoom position, which has been changed in the wide-angle direction, in a telephoto direction. In association with the change in the zoom position in the telephoto direction, the controller causes the image capture unit to perform automatic image capture.
