Abstract: PROBLEM TO BE SOLVED: To generate a natural composite image corresponding to an object image pickup. SOLUTION: A positional deviation quantity (d), corresponding to the reference image of each image (xS1) other than a reference image (xL1) respectively detected, positional deviation for the reference image of each image other than the reference image, is corrected on the basis of the positional deviation quantity and subsequently, respective images (xS4) are combined other than the reference images and reference images whose positional deviation is corrected. By so doing this, image degradation that takes place when a plurality of images are combined can be avoided, and consequently, a natural composite image corresponding to an object of image pickup can be generated.

Abstract: PROBLEM TO BE SOLVED: To eliminate unnaturality of a picture that is generated by synthesizing and compressing a plurality of pictures photographed by different exposure. SOLUTION: A level correction device 12a of the image pickup device 10 corrects a level of a picture xL(i,j) for long time exposure obtained by an image pickup device 11 on the basis of the exposure to generate a corrected picture xL'(i,j) and a level correction device 12b corrects a level of a picture xS'(i,j) for short time exposure obtained by the image pickup device 11 on the basis of the exposure to generate a corrected picture xS'(i,j). An image synthesizer 13 of the image pickup device 10 synthesizes the corrected pictures xL'(i,j), xS'(i,j) to generate one synthesized picture x(i,j). A dynamic range compressor 14 compresses the synthesized picture x(i,j) to generate a compressed picture y(i,j), which is outputted externally.

Abstract: PROBLEM TO BE SOLVED: To correct gradations by avoiding partial deterioration in contrast by deciding the area that image data belong to according to the feature quantities of respective pixels and correcting the pixel values of the image data according to a correction coefficient. SOLUTION: A feature quantity filter 9 detects and outputs feature quantities as to respective pixel values x(i,j) by using an image pickup result VT. An area decision filter 10 decides the area that the input image data belong to based on the detected feature quantities xmax(i,j) and outputs the decision result. A coefficient calculating circuit 11 generates contrast correction coefficients g(i,j) from a specific coefficient calculation function corresponding to the signal levels of low-frequency components r(i,j). Further, a multiplying circuit 12 multiplies the pixel values x(i,j) by the generated contrast correction coefficients g(i,j) to correct the signal level of the image pickup result VT by the contrast correction coefficients g(i,j) and output the result.

Abstract: PROBLEM TO BE SOLVED: To evade the partial contrast from lowering and to correct the gradation by increasing the resolution of the deciding result if the pixel value directly or indirectly approximates to an edge when a correction coefficient is generated based on the deciding result of an area to which the input image data belong and the pixel value is corrected. SOLUTION: An area deciding filter 9 decides an average luminance level area to which the input image data belong and outputs this deciding result r (i, j) via an average luminance level, i.e., a low frequency component of an input image. Meanwhile, a bright area signal generation circuit 9L generates and outputs a bright area deciding result rL (i, j) which increases its resolution as it approximates to every edge of an image pickup result at the bright area side having a high luminance level based on the deciding result r (i, j). A coefficient calculation circuit 10 generates a contrast correction coefficient g (i, j) based on a coefficient calculation function and in response to the signal level of the deciding result r (i, j).

Abstract: PROBLEM TO BE SOLVED: To correct gradation by efficiently preventing partial lowering of contrast by deciding an area to which inputted image data belong and correcting the signal level of the image data based on the decision result. SOLUTION: An image pickup result VN of normal exposure by electric charge storage time set by a user and an image pickup result VS of shot time exposure by short electric charge storage time are outputted alternately, and an image pickup result VT is generated by being composited by a level correcting circuit 6 and an adding circuit 5. A low-frequency component r(i, j) as an average value of pixel values is detected, fine structure in an image is removed and an area with a flat pixel value is extracted by an area deciding filter 10. A contrast correction coefficient g(i, j) is generated, depending on a signal level of the low frequency component r(i, j) by a coefficient calculating circuit 11, and thus the pixel value is corrected by a multiplying circuit 12, the pixel value is corrected and outputted by a gain according to each area based on the low-frequency component r(i, j).
