Embodiment approach 1
[0094] figure 1 It is a block diagram for explaining the configuration of Embodiment 1 of the present invention, figure 1 The portion surrounded by a dotted line in , represents the configuration of Embodiment 1 of the image display control device of the present invention.
[0095] The image to be processed input by the image input unit 1 is temporarily held by the input image storage unit 2 . On the other hand, the setting of the display timing is performed by the display timing generation unit 3 .
[0096] When the image to be processed input by the image input unit 1 is a still image, the display timing is preferably set at an appropriate time interval, for example, every 1 / 60 second, every 1 / 30 second, every 1 / 24 Seconds, etc., as a standard time interval for moving images. Also, when the input image is a moving image, it is preferable to have a time interval corresponding to the frame rate set for the image or a frame rate that is an integral multiple thereof. Also,...
Embodiment approach 2
[0129] Embodiment 2 is more suitable for displaying still images and displaying moving images at N times the frame rate.
[0130] Figure 10 is a block diagram showing the configuration of Embodiment 2 of the present invention, and figure 1 same, Figure 10 The portion surrounded by a dotted line in , represents the configuration of Embodiment 2 of the image display control device of the present invention. Should Figure 10 shown in the composition, as with figure 1 The same constituent elements are provided with an image input unit 1, a display timing generation unit 3, a division position generation unit 4, an image division unit 5, an image overlap position detection unit 6, an image correction unit 7, and image projection units PJ1, PJ2, . . . PJN, in addition, also has: a corrected image storage unit 10, which stores the image corrected by the image correction unit 7; a mask data generation unit 11, according to the image repeat position information from the image r...
Embodiment approach 3
[0147] Figure 16 to Figure 20 This is an example of applying the present invention to an image projection unit using an optical switching element such as a DMD.
[0148] As a configuration of an image projection unit using an optical switching element such as a DMD, it is conceivable Figure 16 The schematic diagram of (A) shows a light transmission type image projection unit, but mostly used Figure 16 (B) The light reflective image projection unit shown.
[0149] as Figure 16 The schematic components of the optical system in the light transmission type image projection unit shown in (A) include a light source 41, a lens 42, a transmission type optical switch element 43, a projection lens 44, and a screen 45 for projecting and displaying an image. . On the other hand, as Figure 16 The schematic components of the optical system in the reflective image projection unit shown in (B) include a light source 41, a lens 42, a reflective optical switch element (DMD, etc.) 43, ...
