Description

つまり、元の画像が３０００×２０００画素であり、縦横２５０画素の正方形ブロックに分割したとすると、領域情報生成回路２０３から出力される画像（代表輝度値からなる画像）は、１２×８画素となる。この画像の各画素の値（代表輝度値）を、領域情報置換回路２０４でゲイン値に置き換えた画像を、元の画像の画素数に線形補間で拡大すれば、拡大後の各画素の値が元の画像の対応する画素のゲイン値となる。 That is, the original image is the 3000 × 2000 pixels, when divided into square blocks of vertical and horizontal 25 0 pixels (image composed of the representative luminance value) image output from the area information generation circuit 203, 12 × 8 pixels It becomes. The value of each pixel of the image (the representative luminance value), an image obtained by replacing the gain value in the area information replacement circuit 204, by extension by linear interpolation with the image number elements of the original image, the value of each pixel after expansion Becomes the gain value of the corresponding pixel of the original image.

Ｓ５０５においてＣＰＵ１０３は、Ｓ５０４により得られた、画像合成に用いる、ガンマ補正後の画像のデータを一次記憶装置１０４に記憶する。ここで記憶された画像データは、後のＳ４０８において使用される。 In step S <b> 505, the CPU 103 stores, in the primary storage device 104, the image data after gamma correction used for image synthesis obtained in step S <b> 504. Image data stored here are used in S40 8 after.
