    摘要： In an image displaying apparatus, first and second detecting units detect quantities of light propagating through a light path at two different locations. A variation calculating unit calculates the variation in the light quantity in the light path based on the quantities of light detected by each of the first and second detecting units. A controlling unit controls the quantity of light propagated to the screen if the variation in the light quantity exceeds a predetermined value.

    摘要： A block noise detector has a spatial difference calculator that calculates differences between values of adjacent pixels. A spatial difference comparator detects edges by comparing the calculated differences. Eight counters count edges detected at different groups of positions spaced eight pixels apart in each horizontal line. The maximum count and the group of positions at which it occurs are detected at the end of each horizontal line to detect block noise and the positions of the block boundaries. The block noise detector is small in size because it only has to count edges in one line at a time, and detects edges accurately by comparing the difference at a given position separately with differences to the left and differences to the right.

    摘要： Motion blur periods (bf) are detected (14) from gradation differences (g1) between a first image signal (d1) and a second image signal (d2), gradation differences (g2) between the second image signal (d2) and a third image signal (d3), and results of the detection of transition periods (h) in the gradations of the second image signal (d2), and the second image signal (d2) is corrected (3) only during the detected motion blur periods (bf). Transition periods (h) are deemed to occur when, for example, the absolute value of a gradation change in the second image signal is greater than a first predetermined threshold value (S1) and less than a second predetermined threshold value S2 (
