A fault detection system for an arithmetic unit includes a shift-and-add type multiplier which is capable of both normal multiplication and division for calculating a quotient as a product of a dividend and an approximated reciprocal of a divisor, a modulo 3 emulator emulating the multiplier in modulo 3 arithmetic, a modulo 3 converter converting the multiplication result of the multiplier into a modulo 3 equivalent, an error detector comparing outputs from the modulo 3 converter and the modulo 3 emulator to detect a bit error, and a control unit. The control unit supplies, to the modulo 3 emulator and the modulo 3 converter, a control signal representing either a normal multiplication mode, a multiplication mode for calculating a product of a divisor and a reciprocal of the divisor, a multiplication mode for calculating a product of a dividend and a reciprocal of a divisor, or a multiplication mode for generating a partial quotient in a division process. The control unit also controls generation of modulo 3 equivalents in the modulo 3 emulator and the modulo 3 converter.

To provide an image processing device that calculates a parameter used for correcting large video jitter with high accuracy even when the accuracy of a sensor for measuring a movement of a photographing device is low. The image processing device includes: a constraint condition generating unit (130) that generates a constraint condition using sensor information such that a parameter value falls within a range; and a parameter calculating unit (140) that calculates the parameter according to the constraint condition. The constraint condition generating unit (130) has: a feature vector generating unit (131) that generates a feature vector showing features of the sensor information; and a motion classifying unit (such as 132) that identifies a movement of the photographing device according to the feature vector generated by the feature vector generating unit (131), on the basis of an association between the feature vector and the movement of the photographing device, the association being obtained as a result of previously-executed machine learning of the feature vector and an actual movement of the photographing device. The constraint condition generating unit (130) determines the range corresponding to the information of the movement of the photographing device, the movement being identified by the motion classifying unit (such as 132).

An image processing apparatus (10) includes: an imaging device (20); an optical system (22); and a distance determining unit (16) determining an object distance between the optical system and the object based on a size of a blur developed on the image. The optical system (22) has a characteristic which simultaneously satisfies both of conditions that (i) variation in magnification is equal to or smaller than the predetermined number of pixels in the case where a focused point is set farthest from and closest to the optical system (22) in a range of the distance of the object determined by the distance determining unit (16) and (ii) variation in a PSF due to an image height of the optical system (22) is equal to or smaller than a predetermined degree so as not to affect the determination of the distance of the object by the distance determining unit (16).
摘要:
An imaging apparatus wherein a captured image is subjected to a rotational transform so as to correct the inclination of one or more subjects in the captured image. The imaging apparatus defines, with reference to a physical inclination detected by a sensor, an angle range in which the image is to be processed. The imaging apparatus then processes the captured image and detects lines therein and inclination angles thereof. The imaging apparatus then creates histograms indicative of frequency distributions of the inclination angles of those lines, and selects, in the created histograms, an inclination angle having a frequency that satisfies a predetermined criterion, as a rotational angle to be used for the rotational transform.
