Patent abstract

When a saturation flag of HDR-RAW data accumulated in a BRAM data accumulating section 19 is “1” and a saturation flag of HDR-RAW data accumulated in an input data accumulating section 18 is “0,” i.e., when a pixel being in a saturated state no longer attains the saturated state, the HDR-RAW data accumulated in the input data accumulating section 18 are recorded to BRAN 10 instead of the HDR-RAW data recorded that far. Therefore, the image data of the pixel within the second image is recorded, and it is not necessary to arrange the delay element. As a result, manufacture cost can be reduced by the amount for arranging the delay element.
