An entertainment system for use with a magnetic resonance imaging (MRI) device has a display panel and associated electronics which are mounted close to the MRI device and which are enclosed within a Faraday shield. A patient may be placed within the MRI device in a variety of positions and may view images from the display panel either directly or through a mirror, prism, or corner reflector. In order for the patient to view the images in the correct orientation regardless of the exact positioning, the display panel can display the images normally, with the images flipped from top to bottom, with the images flipped from left to right, and with the images flipped both from top to bottom and from left to right. The display panel is formed with a dark-colored focus area which forms a border around the display panel and which directs the attention of the patient toward the images on the display panel. The entertainment system indicates the various states of the MRI procedure through a set of lamps colored and arranged to simulate a typical traffic light. By using the traffic light configuration and coloring, patients can easily determine the state of the MRI procedure. The entertainment system calms the patient, distracts the patient from the MRI procedure, and makes it easier for the patient to remain still during the MRI procedure. As a result of the entertainment system, better quality images may be obtained with the MRI device.

Disclosed is a method and apparatus for mixing internally generated or stored video with an external video and driving an LCD display device. External video is clocked into a dual port external frame store. Internal video is either internally generated or read from an internal mass store device and stored in an internal frame store and in a preferred embodiment, the internal video data includes an embedded code which serves to select on a pixel by pixel basis the appropriate frame store signal, either external or internal for display on the LCD panel. By adjusting the start number on row and column counters for reading out data from the external frame store, panning of an external video image can be accomplished. By repeating the readout of the external frame store selectively, a 'zoom' of the image can be provided to an LCD display device. By reversing either the direction in which the external video is stored in the frame store or the direction in which columns of information are read out, the displayed image can be reversed permitting rear projection of an accurate image.

Disclosed is a method and apparatus for converting interlaced input video to a sequential output compatible with sequential input display devices. The video input is digitized and decoded so as to provide separate luminance or chrominance information for each pixel to a line buffer memory. A line derived frequency reference from the input video serves to reference a pixel clock which clocks pixel information into the memory and clocks pixel information out of the memory at twice the pixel clock rate. The decoder also digitizes the luminance/chrominance information prior to storage in the memory and, as this information is read out of the memory, it is converted back into analog data by a suitable D-A converter and then is converted into appropriate format to provide red, green and blue video output information for operating sequential input devices.
