Electronic binoculars include an imaging unit, a first binocular unit, a second binocular unit, and a mode selector. The imaging unit captures an image of an object. The first binocular unit includes a first ocular unit through which the object is observed based on signals from the imaging unit. The second binocular unit includes a second ocular unit through which the object is observed based on signals from the imaging unit. The mode selector selects at least one of first and second modes. The first mode fully supplies electricity to each of the first and second binocular units. The second mode at least partially suspends the electricity supply to the second binocular unit.

Electronic binoculars

Electronic binoculars comprise an imaging unit, and first and second ocular units. The imaging unit has an imaging device that projects an optical image of an object, and converts the optical image to electric signals. The first ocular unit has a first image-indicating device that indicates the object image based on the electric signals in a first image-indicating field. The second ocular unit has a second image-indicating device that indicates the object image based on the electric signals in a second image-indicating field. The first image-indicating field is smaller than a first effective image-indicating area which is the maximum image-indicating area of the first image-indicating device. The second image-indicating field is smaller than a second effective image-indicating area which is the maximum image-indicating area of the second image-indicating device. The respective first and second image-indicating fields can move within the respective first and second effective image-indicating areas.

A telescope main body, which is provided with an objective optical system, a focusing system, an imaging device, a beam splitter, and a correcting system that performs a correcting operation for correcting a position shift between an image forming position of an object image and a receiving surface of the imaging device caused by diopter variation of a user. The correcting system includes a focus driving system which relatively moves an image forming position of the object image with respect to the receiving surface, a focus detecting system which detects a status in which the image forming position coincides with the receiving surface, and a controller controlling the focus driving system. The controller has with a learning function of storing correction data of a preceding correcting operation so that the stored correction data of the preceding correcting operation is reflected in a subsequent correction operation.

Electronic binoculars comprise an imaging unit, an image-signal processing unit, and first and second ocular units. First and second optical images, obtained by the optical system, are converted to first and second electric signals, due to imaging operations of the first and second imaging devices. The imaging operations of the first and second imaging devices are simultaneously started, and ended at different times. The image-signal processing unit superimposes the first and second electric signals to generate a third electric signal. The first and second ocular units indicate object images based on the third electric signal.

An electronic camera is provided that prevents deterioration of quality of an object image obtained by an image-pickup device due to dust adhered on an optical element. The electronic camera includes an ion generator for taking off the electric charges from the optical element, such as a low-pass filter, arranged in front of the image-pickup device. The ion generator is provided in the camera body and ionizes the air inside the camera body. The ionized air diffuses toward the low-pass filter and binds with the charge on the low-pass filter. Thus, the electric charge of the low-pass filter is taken off and the low-pass filter does not attract dust which cause the quality decrease of the object's image obtained by the image-pickup device.

A cover plate for covering an opening of a casing in which a solid state imaging device is disposed. The cover plate comprises a transparent cover plate member and a conductive film layer. The cover plate hermetically covers the opening of the casing and the conductive film layer covers the outermost surface of the transparent cover plate member. The transparent cover plate member is comprised of a plurality of laminated transparent plates such as lithium niobate plates for an optical low-pass filter and a plate for an infrared cut-off filter. An example of the conductive film layer is a metallic film such as Cr or Au, coated on the surface.

An electronic camera (digital camera) includes a taking optical system that forms an image of a subject, a lowpass filter and a CCD area sensor that captures the image formed by the taking optical system. The lowpass filter is mounted on a driving mechanism that moves it in the direction parallel to a light-receptive surface of the CCD. The driving mechanism consists of a pair of filter guides that support the filter, a pair of shafts that guide rectilinear movement of the filter, a cam disc that is rotated by a motor and a cam follower attached on the guide. When the picture is taken, the motor rotates the disk, which reciprocates the filter. Since the movement of the lowpass filter moves the shadow of the dust formed on the CCD area sensor, an influence of the shadow is diffused among a larger number of pixels.

A hybrid camera of the present invention selectively uses one of a photographic film and an image sensor, to record an object image. The hybrid camera has a photographing optical system, a body, and a film positioner. The film positioner is detachably mounted in the body and defines a position of an exposure area of the photographic film, along an optical axis of the photographing optical system. An accommodation space, which can accommodate the image sensor, is formed in the body by detaching the film positioner. When using the photographic film, the film positioner is mounted in the body such that the position of the exposure area coincides with a position of a focal plane, defined by the photographing optical system. Then, when using the image sensor, the film positioner is detached from the body and the image sensor is placed in the accommodation space, such that a position of a light-receiving area of the image sensor coincides with the position of the focal plane, along the optical axis.

A view finder device has a Poro prism and a first optical system facing an emergent plane of the Poro prism. The first optical system is positioned beside the Poro prism and opposite to a recording medium passage through which an electro-developing recording medium is moved. A relay optical system is provided behind the recording medium passage, so that the eye point of the view finder is separated from the first optical system. A second optical system is provided behind the relay optical system, so that the image formed by the relay optical system is observed. Since the electro-developing recording medium can be moved between the first optical system and the relay optical system, the finder optical system can be disposed at a lower position.
