Abstract:
1. An image data processor for generating driving image data for operating an image display device, comprising: an image memory; a write-in control section that sequentially writes-in plural frame image data having a predetermined frame rate to the image memory; a read-out control section that reads-out the frame image data 1 times (1 is an integer of 2 or more) at a rate 1 times the frame rate with every frame image data written into the image memory; a driving image data generating section that generates the driving image data corresponding to each read-out image data sequentially read out of the image memory; in the read-out image data corresponding to a certain first frame and the read-out image data corresponding to a second frame continued to the first frame, the driving image data generating section setting image data provided by replacing at least one portion of each read-out image data with mask data to the driving image data with respect to first read-out image data of a 1-th period finally read out as the read-out image data corresponding to the first frame, and second read-out image data of the first period firstly read out as the read-out image data corresponding to the second frame; the driving image data generating section also setting the read-out image data to the driving image data as they are with respect to the read-out image data read out in at least one period among the read-out image data except for the first read-out image data of the first frame; and the driving image data generating section also setting the read-out image data to the driving image data as they are with respect to the read-out image data read out in at least one period among the read-out image data except for the second read-out image data of the second frame.
