A medical device for use on the human eye is described. The device is placed in an extrocular location in a patient and delivers an electrical current that stimulates the retina of patients who are blind or have vision disorders. It has at least one electrode that makes contact with the scleral surface of the eye, the electrode typically being activated by an electrical stimulator. The device produces electrical pulses which pass through the electrodes on the scleral surface of the eye, to activate the retina of the eye, which causes the patient to experience improved vision, visual sensations or the prevention of deterioration of vision. By this means, sight can be restored or improved where patients have disorders of their retina or other parts of their visual system.

A method and apparatus for providing spatial scalable compression of a video stream is disclosed. The video stream is downsampled to reduce the resolution of the video stream. The downsampled video stream is encoded to produce a base stream. The base stream is decoded and upconverted to produce a reconstructed video stream. The reconstructed video stream is subtracted from the video stream to produce a residual stream. It is then determined which segments or pixels in each frame have a predetermined chance of having a predetermined characteristic. A gain value for the content of each segment or pixel is calculated, wherein the gain for pixels which have the predetermined chance of having the predetermined characteristic is biased toward 1 and the gain for other pixels is biased toward 0. The residual stream is multiplied by the gain values so as to remove bits from the residual stream which do not correspond to the predetermined characteristic. The resulting residual stream is encoded and outputted as an enhancement stream.

The subject application is directed to a system and method for device-specific image manipulation. First, output device capability data corresponding to capabilities of available document output devices is stored in associated memory. Electronic document data having image data corresponding to a plurality of sub-images is then received. Device selection data is then received corresponding to a selected document output device. Capability data representing the output capabilities of the selected device is then retrieved. Image characteristic data is then determined and tested relative to the device output capability data. Selected sub-images are then merged into a single image and the image is classified in accordance with the image characteristic data. Resolution and colorant reduction are then determined in accordance with the testing output. The determined resolution and colorant reductions are then applied to the single image of the received electronic document data and output by the selected document output device.
