Title: IMAGE PROCESSING DEVICE, METHOD, PROGRAM, AND STORAGE MEDIUM ON WHICH SAID PROGRAM IS RECORDED, AND DISPLAY DEVICE
Abstract:
An image processing device (20) as shown in Figure 2 is equipped with a region subdividing means (21), a level determination means (22), a statistical calculation means (23), a gain determination means (24), a time constant processing means (25), a dynamic processing means (26), a filtering processing means (27), and a multiplication processing means (28), etc., for various types of programs. The region subdividing means (21) recognizes input image data and subdivides it into a plurality of regions. The statistical calculation means (23) executes statistical calculation for each of the subdivided regions. The statistical calculation means (23) is equipped with a region average brightness calculation means (231), a subject average brightness calculation means (232), and an average absolute value of difference calculation means (233). The gain determination means (24) determines the gain in each region based on the calculation results computed by the statistical calculation means (23). The dynamic processing means (26) determines the gain of each pixel in each region.
