A portable, lightweight digital imaging device uses a slit scanning arrangement to obtain an image of the eye, in particular the retina. The scanning arrangement reduces the amount of target area illuminated at a time, thereby reducing the amount of unwanted light scatter and providing a higher contrast image. A detection arrangement receives the light remitted from the retinal plane and produces an image. The device is operable under battery power and ambient light conditions, such as outdoor or room lighting. The device is noncontact and does not require that the pupil of the eye be dilated with drops. The device can be used by personnel who do not have specialized training in the eye, such as emergency personnel, pediatricians, general practitioners, or volunteer or otherwise unskilled screening personnel. Images can be viewed in the device or transmitted to a remote location. The device can also be used to provide images of the anterior segment of the eye, or other small structures. Visible wavelength light is not required to produce images of most important structures in the retina, thereby increasing the comfort and safety of the device. Flexible and moderate cost confocal and fluorescent imaging, multiply scattered light images, and image sharpening are further functionalities possible with the device.

The ability to remove a watermark from an encoded image opens the possibility of various novel applications. Several such applications are detailed. One employs a reversible watermark in conjunction with a second (robust) watermark. In this arrangement, the payload of the reversible watermark conveys information about the robust watermark (e.g., encoding parameters, or an error signal), permitting removal of the robust watermark from an uncorrupted encoded image. By such arrangements, the encoded image can be fully restored to its pristine, unencoded state even if several different watermarks have been applied.

A test pattern is moved on a screen 5 subject to measurement with the field of view of an image sensor pursuing the motion of the test pattern so as to observe BEW. Subsequently, the field of view 33 of the image sensor is moved at the same velocity vc as in the foregoing observation to capture an image of a static pattern PE, and a blur width W along the scrolling direction that appears in a distribution profile of the captured image is observed. Based upon the blur width W and the exposure time of the image sensor for capturing the image of the static pattern PE, the moving velocity of the test pattern at the time of observation of the BEW is estimated, and by using the moving velocity, the BEW is normalized. Evaluation of the moving image quality of the screen is carried out by using the normalized N BEW. The moving velocity of the original test pattern can thus be estimated easily and accurately, and accordingly, the moving image quality of the screen can be evaluated accurately.
