Abstract: The invention relates to a method for recording and displaying fluorescence images with high spatial resolution. Several recordations of an image of an object are made sequentially with an electronic camera and, between recordations, the image of the object and the electronic camera are shifted relative to each other. The recordations are subsequently unified to a compiled image of higher spatial resolution. Before or after the partial images are brought together, the signals, which belong to image points of the images and which are obtained at different times, are amplified with amplification factors which are dependent upon the time intervals between the image recordations and are essentially reciprocal to the time dependency of the fluorescence. Artefacts caused by decreasing fluorescence intensities (fading, bleaching) are thereby avoided. These fluorescence intensities decrease as a function of time.

Abstract: Two plane parallel plates, orthogonally intersecting each other, are provided in front of a CCD device. The plane parallel plate is supported by its two ends which are deviated from an optical path. Each end of the plane parallel plate includes an armature made of soft electromagnetic iron, and two electromagnets are provided in the optical axis direction, while sandwiching each armature. By the on/off state of the two electromagnets, the armature can control the optical device in three angled positions, thus the optical device can have three shift positions with respect to the optical axis.

Abstract: In an image sensing apparatus of this embodiment, a variable angle prism for preventing a camera shake is used to attain a pixel shift. Consequently, low resolution images free from a blur and high-resolution images obtained by the pixel shift can be selectively obtained with an extremely simple arrangement. Whether a resolution increasing function is to be executed is properly determined in accordance with photographing conditions. Therefore, the resolution increasing function has no adverse effect on other functions. In addition, a power-saving effect can be enhanced since an unnecessary resolution increasing function is not performed. Since the resolution can be further increased by using a conventional camera shake preventing device, a larger amount of a high-frequency component can be detected. Consequently, focus detection can be performed accurately.

Movement of the imaging sensor is controlled based on the calculated target vector, so that the imaging sensor is moved back to the reference position thus correcting the deviation.
