A steering angle is corrected with reduced complicatedness in handling. Provided is a steering angle correction method, including: acquiring a measurement image of a steered wheel () in correspondence with a steering angle of a mobile object () at which the measurement image is captured; calculating a degree of coincidence between the steered wheel () on the measurement image and the steered wheel () on a reference image of the steered wheel () captured at a reference steering angle; and calculating a correction value used to correct the steering angle, based on the degree of coincidence.

Calibration operation device and calibration operation method

An imaging apparatus and an imaging method able to obtain images having no blurring with a small number of images under different exposure conditions and capable of shortening a processing time, wherein an imaging apparatuscaptures a plurality of images including an image having a short exposure time and high resolution, but having much noise and an image having a long exposure time, but having little noise and low resolution by an optical systemand an imaging element. After the signal processing of a signal processing part, a CPUdetects positional deviation among the captured images and blurring, changes the ratio of the plurality of images according to the distances from the edge, and combines these to thereby form an image free from blurring and reducing noise.

Camera device, camera system and camera calibration method

A data thinning unit prepares thinned images by extracting only one component in raw data of each of a standard image and reference image, a block extracting unit extracts a search block and a template block for finding residual differences, a luminance difference comparing unit obtains a difference between the maximum value and the minimum value of luminance values of each block, and, when smaller than a threshold value, excludes this from a scope of acquisition of residual differences. The residual difference acquiring unit acquires residual differences from blocks which were not excluded, a block selecting unit selects a predetermined number of blocks having small residual differences, and a hand shake (blur or unintentional movement) acquiring unit finds a position of the template block at which the residual difference becomes the minimum, calculates a center value of all positions, and defines the same as the amount of hand shake.

Shaking detection device, shaking correction device, imaging device, and shaking detection method

An imaging device and its image processing for creating an image with less blur from a small number of images under different exposure conditions in a shortened processing time. The imaging devicecaptures an image by means of an optical systemand an imaging elementin a short exposure time with a high resolution and much noise and images in a long exposure time with low resolution and less noise. After signal processing by signal processing section, a CPUdetects the position variation between captured images and blurs, separates the edges blur and the noise by using the threshold from the two difference images, combines the two images at a varied combination ratio, and thereby creates an image with no blur and reduced noise.
