Abstract: Image processing performed by a processor and including acquiring a first fundus image of an examined eye, acquiring a position for acquiring a tomographic image of the examined eye's fundus, acquiring a second fundus image of the examined eye, determining the acquired position is included in a specific range of the first fundus image, and computing a first movement amount of the examined eye in a case in which the acquired position is included in the specific range, using first registration processing to positionally align the first fundus image and the second fundus image, and computing a second movement amount of the examined eye in a case in which the acquired position falls outside the specific range, using second registration processing to positionally align the first fundus image and the second fundus image, the second registration processing being different from the first registration processing.

Abstract: A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.

Abstract: A first image is projective transformed into a reference image by using a projective transformation matrix on each pixel of the first image. A projective transformation matrix for transforming a tilted image n into a central image G0 is computed based on positions of combinations of twelve corresponding points indicated in a combination of the central image G0 with the tilted image n. The computed projective transformation matrix is then employed to perform a projective transformation of the tilted image n. A projective-transformed tilted image n1 is created thereby.

Abstract: Predicting a non perfusion area. An enhancement image processing section performs enhancement image processing on a fundus image of a subject eye to enhance vascular portions (304). A prediction processing section predicts a non perfusion area in the fundus image that has been subjected to the enhancement image processing (306 to 312). A generation section generates a non perfusion area candidate image (314).

Abstract: A processor acquires a first fundus image of an examined eye including a foreground area and a background area other than the foreground area. The processor also generate a second fundus image by performing background processing to replace a first pixel value of a pixel configuring the background area with a second pixel value different from the first pixel value.
