  • Patent number: 10021386
    Abstract: The present technique relates to an image processing device and a method that can improve encoding efficiency in multi-viewpoint encoding. A reference image index allocation unit alternately allocates a reference image index referred by a motion estimator/compensator to predict an image to be processed to a referable image in a view direction and to a referable image in a time direction. In allocation, the reference image index allocation unit refers to time information and view information of the reference image accumulated in a decoded picture buffer, information such as a sequence parameter set and a slice header from a syntax processing unit, and the like.

  • Patent number: 9041807
    Abstract: An image processing device configured to be installed in a vehicle includes an image acquirer, an image selector, a first luminance adjuster, a synthetic image generator, and an image provider. The image acquirer acquires camera images captured by cameras provided on the vehicle. The image selector selects one of the camera images as a representative image based on luminances of the camera images. The first luminance adjuster adjusts a luminance of at least one of the other camera images based on a luminance of the representative image. The synthetic image generator generates a synthetic image showing a periphery of the vehicle, based on the representative image and the other camera images the luminance of at least one of which has been adjusted by the first adjuster. The image provider outputs, to a display device installed in the vehicle, information corresponding to the synthetic image.

  • Patent number: 7440005
    Abstract: In an endoscope, scopes that include a scope-side memory and a connector are selectively and detachably connected to a processor that includes a processor-side memory and a connection member. A parameter stored in the scope-side memory can be written to the processor-side memory. The connector that is connectable to the connection member is used for connecting the scope to the processor. When the connection member that is movable is in the first position, the connector is detachably connectable to the connection member. When the connection member is in the second position, the subject is observable. When the connection member is moved from the first position to the second position, the parameter is written to the processor-side memory. When the connection member is moved from the second position to the first position, the parameter is written to the scope-side memory.

  • Publication number: 20070229655
    Abstract: An assembly for securing the eyepiece of an endoscope to a digital camera includes a bar that supports the camera and a block that supports the eyepiece. The camera can be secured to the bar using the camera's tripod mounting hole. The block can normally move in three orthogonal linear directions relative to the bar, but can also be locked in a selected position relative to the bar. In this manner, the assembly can be adjusted so that the eyepiece of the endoscope contacts or nearly contacts the end of the barrel of the digital camera secured to the camera bar. Then, the support block can be locked into position to clamp the endoscope to the digital camera. A sheet is attached to one of the components and can be draped over the camera prior to use of the camera in a sterile environment.

  • Patent number: 6932760
    Abstract: An autoclavable endoscopic optical coupler includes the capability to optically couple an endoscope and a camera, so that a focused image will be communicated to the camera head. Furthermore, the coupler has the capability of withstanding multiple autoclave sterilization treatments without allowing moisture to penetrate the interior. The coupler includes a lens holder assembly that has an endobody on one portion and a second portion that is inserted into and coupled to a coupler body. The coupler body has a camera attached at one of its ends. A focus ring is physically coupled to the coupler body, which is coupled to the lens holder assembly. Turning the focus ring causes a translation motion of the lens holder assembly and endoscope with respect to the camera head.

  • Patent number: 6791618
    Abstract: A photographing system comprising a photographing-method input unit, a temporary exposure time setting unit, and an actual exposure time setting unit. The photographing-method input unit receives input of a photographing method. The temporary exposure time setting unit stores a look-up table in which the kind of photographing method is caused to correspond to a temporary-photographing exposure time that is used to obtain an appropriate actual-photographing exposure time. The temporary exposure time setting unit also obtains the temporary-photographing exposure time in accordance with the kind of input photographing method by making reference to the look-up table and inputs the obtained temporary-photographing exposure time to a camera controller. The actual exposure time setting unit sets an actual-photographing exposure time, based on a temporary-photographing image signal obtained in temporary photographing controlled by the camera controller in accordance with the temporary-photographing exposure time.
