A solid-state imaging element 2 having a light-receiving portion where a plurality of photoelectric conversion elements 21 are arranged, and electrode pads 22 electrically connected to the photoelectric conversion elements 21 is mounted on a substrate 1. A scintillator 3 is formed on the surface of the light-receiving portion of the solid-state imaging element. Around a support surface 10 where the solid-state imaging element 2 of the substrate 1 is mounted, holding portions 14 and 15 are formed on opposing side walls to hold and project the surface of the light-receiving portion from a vapor deposition holder toward a vapor deposition chamber in forming the scintillator 3.

Apparatus and method for the display of autostereoscopic images, in which two or more perspective views are generated by a single transmissive display screen is provided. A structured light source behind the screen directs light through different sets of display elements to correspondingly different viewing zones. The structured light source includes two crossed arrays of cylindrical convergent optical elements, two linear arrays of polarisation altering elements which, in conjunction with the convergent arrays and the first polariser of the LCD, prevent light from passing through a particular set of display elements and reaching the wrong viewing zone. In some variations, one or both of the polarisation altering arrays may be programmed. Observer co-ordinate data permits the correct viewing zone to be co-located with each of the observer's corresponding eyes and includes devices for accommodating changes in the observer's distance from the display. The displayed image adapts to the observer's location. All or part of the display may provide conventional two-dimensional images at the screen's full resolution.

A solid-state imaging element 2 having a light-receiving portion where a plurality of photoelectric conversion elements 21 are arranged, and electrode pads 22 electrically connected to the photoelectric conversion elements 21 is mounted on a substrate 1. A scintillator 3 is formed on the surface of the light-receiving portion of the solid-state imaging element. Around a support surface wherein the solid-state imaging element 2 of the substrate 1 is mounted, positioning portions 14 to 16 are formed, which project higher than the support surface and position the solid-state imaging element 2 with side walls. The top surfaces of these positioning portions are formed such that a light-receiving surface 2a of the solid-state imaging element 2 is higher than the top surfaces.

An image device, such as a digital camera, detects specific repeating patterns of signal variations by processing columnar information from the device's two-dimensional sensor array used to generate images. In one embodiment, the columnar information is derived from calculating row averages for two image frames, with each row average being a computed average of the multiple signal intensities generated from some or all of the sensors within a particular row. After the columnar information is determined for each of the two frames, a difference signal is generated as a sequence of the differences between the row averages for the first frame and the row averages for the second frame. This row averaging and frame differencing removes a large percentage of the signal energy that is not a result of the artifact of interest, such as the flicker generated by illumination having intensity fluctuations at 100 Hz or at 120 Hz. In some embodiments of the invention, the row averaging and / or the frame-to-frame comparison are deleted.
