In a pixel circuit that accumulates a display signal Vsig in a capacitor and supplies a display current to a light-emitting element using a TFT serving as a drive transistor in order to correct fall of a luminance due to aged deterioration of the light-emitting element, the pixel circuit supplies the display current to a gate of a TFT and sets a source of the TFT to a value obtained by deducting a threshold value of the TFT from an anode potential of the light-emitting element with respect to the display current using a variable bias voltage to thereby extract an amount of an increase of a voltage due to the aged deterioration of the light-emitting element as a source-to-drain current of the TFT. The pixel circuit feeds the source-to-drain current from the capacitor as a correction signal and adjusts a gate potential of the TFT serving as the drive transistor to thereby correct the display current and correct a luminance of the light-emitting element.

A method/system preserves annotations of different pathological conditions or changes that are recognized on cross-sections within a three dimensional volume of a patient's eye so that the annotations are maintained in a visible state in an en face projection produced with a SVP technique. It is thus possible to coregister the annotated conditions or changes with other types of two dimensional en face images such as images from other ophthalmic devices (e.g., angiography device, microperimetry device, autofluorescence device, fundal photography device.). The annotations are also maintained in a visible state in the coregistered image.

Direct optical imaging of anatomical features and structures from within a biological organ in a dynamic environment (where the tissue being imaged is in motion due to cardiac rhythms, respiration, etc) presents certain image stability issues due (and/or related) to the motion of the target structure and may limit the ability of the user to visually interpret the image for the purposes of diagnostics and therapeutics. Systems and mechanisms for the purpose of actively stabilizing the image or for compiling and re-displaying the image information in a manner that is more suitable to interpretation by the user are disclosed.

To make it possible to stably provide a stereoscopic image which can be viewed by each viewer in the state where the stereoscopic effect and the sense of reality are maximized. Left eye and right eye images (images for measurement), the parallax between which is continuously or stepwise changed, are outputted beforehand to a stereoscopic image display device, and the face of the viewer viewing the images for measurement is photographed. The pupil width of the photographed viewer is measured, and based on the state of the change in the pupil width, the fusion limit of the viewer is measured and registered. In the case where a stereoscopic image for appreciation is displayed, the stereoscopic image is outputted by controlling the parallax of the stereoscopic image so as to prevent the parallax from exceeding the fusion limit of the viewer, which is measured beforehand.
