Abstract: 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 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.

Abstract: 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.
