In one example, digital image frames are accessed, each of the digital image frames having an associated control value for an automatic image capture processing function. A measure of information content change is determined for a current digital image frame relative to at least one previous digital image frame. A measure of information content reliability with respect to the automatic image capture processing function is determined for the current digital image frame. The control value associated with the current digital image frame is corrected based on the determined measure of information content change and the determined measure of information content reliability. A final control value for the automatic image capture processing function is output based on corrected control values for one or more digital image frames.

The purpose of the present invention is to correct the reduced degree of modulation in a diagonal direction in a four-plate camera having a frame memory and R, G1, G2, and B image pickup elements among which two green image pickup elements (G1, G2) shift pixels diagonally. This image pickup method is provided for an image pickup device having two green image pickup elements, a red image pickup element, and a blue image pickup element among which the two green image pickup elements shift pixels diagonally. The method includes, with respect to a contour correction target pixel, generating a diagonal contour correction signal from respective image signals of two diagonally upper left pixels, two diagonally upper right pixels, two diagonally lower left pixels, and two diagonally lower right pixels, and adding the diagonal contour correction signal to an image signal of the contour correction target pixel.

A method for determining a neural network for correcting optical aberrations includes determining one or more images that are at least partly related to an optical system or the design of an optical system. A neural network is determined on the basis of the determined one or more images in such a way that the determined neural network when applied to an image captured by the optical system outputs an image which has been corrected in relation to one or more optical aberrations.

Analyte arrays such as solutes in a slab-shaped gel following electrophoresis, and particularly arrays that are in excess of 3 cm square and up to 25 cm square and higher, are imaged at distances of 5 cm or less by either forming sub-images of the entire array and stitching together the sub-images by computer-based stitching technology, or by using an array of thin-film photoresponsive elements that is coextensive with the analyte array to form a single image of the array.

Flare compensation includes receiving a first image and a second image; converting the first and the second images from an RGB domain to a YUV domain; obtaining an intensity differences profile along a stitch line between the first and the second images, where the intensity differences profile is obtained for the Y component; obtaining a dark corner intensity differences profile between the first and the second images based on a relative illumination of an area outside a first image circle of the first image and a second image circle of the second image, where the dark corner intensity differences profile is obtained for the Y component; obtaining a flare profile using the intensity differences profile and the dark corner intensity differences profile; converting the flare profile of the Y component to an RGB flare profile; and modifying one of the first or second images based on the RGB flare profile.
