Imaging display method and imaging display device

摘要

An imaging display device of the present invention comprises an imaging element 1 photoelectrically converting an optical image, a readout control unit 6 controlling a readout position of the imaging element 1, an image processing unit 2 processing image signal readout from the imaging element 1, an image display unit 4 displaying image signal output from the image processing unit 2, a pixel shift unit 5 shifting an observation pixel position displayed on the image display unit 4, a pixel shift control unit 7 controlling the pixel shift unit 5, and a system control unit 8 controlling the readout control unit 6 and the pixel shift control unit 7 so that image signal photoelectrically converted by the imaging element 1 is displayed on the image display unit 4 and shifted by the pixel shift unit 5. ;According to the present invention, it is possible to reduce delay time from imaging to displaying and to raise spatial resolution and motion resolution.

主权项

1. An imaging display method comprising the steps of:
shifting a display position of a n image display unit by a shifting operation; acquiring image signals of plurality of fields, having different readout positions, from an imaging element that photoelectrically converts optical image depending on the display position; and controlling the display position by the shifting operation and a readout position of the imaging element, and displaying the image signals of the plurality of fields on the image display unit at a timing synchronized with the shifting operation; wherein the imaging element has more pixels than the pixel count of the image display unit, and pixel counts of the image signals of the fields are converted to the pixel count of the image display unit and the converted image signals are displayed on the image display unit, and wherein when the display position is in an initial position, an image signal of a select field is read out by sub-sampling pixels of the imaging element by a select interval; and when a display element is in a position shifted to a select direction from the initial position, an image signal of another select field is read out by shifting a readout position of each pixel on the imaging element to the select direction and sub-sampling pixels of the imaging element by the select interval to acquire image signals of a plurality of fields.
