A method, image processing apparatus, and computer readable medium for image enhancement are provided. In the method, a low-resolution image is received and upscaled to generate an upscaled image having first pixels. Edge detection is performed on the upscaled image to obtain edge information of the first pixels. Each piece of the edge information includes an edge direction and an edge intensity, and each of the edge directions includes a horizontal and vertical component having a constant summation. A non-edge region of the upscaled image is enhanced to generate a high-resolution detail image; based on unsharp masking sharpening methods, an edge region of the low-passed upscaled image is enhanced according to the horizontal and vertical components of the edge directions to generate a high-resolution edge image. Image fusion is performed on the high-resolution edge image and the high-resolution detail image according to the edge intensities to generate a super-resolution image.

Visual or photic stimuli generating methods, devices and control systems for inducing steady-state visual evoked potential (SSVEP) from human viewers without causing discomfort to the viewers or distorting the embedding images are disclosed. The control system includes a stimuli-generating device and an electroencephalography (EEG) sensing device. The stimuli-generating device includes a first and a second light source. The first light source generates a flickering light with a first wavelength while a second light source generates another flickering light with one or more wavelength(s) differ from that of the first one. Together, the light sources generate visual/photic stimuli flickering above their critical flicker fusion threshold while maintaining the colorfulness and hue of the embedding images. At least one electrode of the EEG sensing device is connected to each viewer, configured to receive and analyze his/her EEG signals in order to detect and determine his/her responses to the stimuli.

A three dimensional display includes a display panel and a view-scanning layer. The display panel is used to display many display images quickly. The view-scanning layer is disposed on the display panel and receives the display images. The view-scanning layer has many light refracting modulation regions. Each of the light refracting modulation regions includes a view-scanning unit. The view-scanning unit changes an ongoing direction of a light according to an applied electric field so as to project a part of each of the display images at different view directions. Here, each of the view directions corresponds to the ongoing direction of the light.
