Abstract: An image tracking apparatus, which tracks a subject in a moving image, comprising: an image acquisition device that acquires image data indicating the moving image; a first detector that detects a first area of a subject in acquired image data to track the first area in the moving image; a second detector that detects a second area of a subject in the image data to track the second area in the moving image; and a controller that tracks the subject by switching between a tracking result of the first detector and a tracking result of the second detector. The first and the second detector operate independently. The controller tracks the subject using the tracking result of the first detector when the first area is tracked, and tracks the subject using the tracking result of the second detector when the first area is not tracked and the second area is tracked.

Abstract: An imaging apparatus includes: an image sensor that captures a subject image formed via an optical system to generate image data; a controller that controls an autofocus operation to focus the optical system; and an image recognizer that identifies, based on the image data, information including a class of a subject in an image shown by the image data, wherein the controller acquires the information identified by the image recognizer to automatically set a parameter indicating characteristics of the autofocus operation, based on a tendency to be estimated as possibility for the subject of the identified class to move on the image.

Abstract: A vehicle control device controls operation of a vehicle provided with a transmission having a direct gear and normal gears including an overdrive gear having a lower gear ratio than the direct gear. The device includes a travel segment determination unit which determines a forward travel segment having a different road slope from a current travel segment, a current gear position selection unit that selects a current gear position in accordance with a shift pattern, a forward gear position selection unit that selects a forward gear position based on a travel resistance of the vehicle in the forward travel segment, and a shift control unit that maintains a gear position as the direct gear while the vehicle travels in the forward travel segment, when a gear position of the transmission in the current travel segment is the overdrive gear and the forward gear position is the direct gear.

Abstract: In this vehicle control device (10), which controls operation of a vehicle provided with a transmission including a direct gear and an overdrive gear, which is a gear with a lower gear ratio than that of the direct gear, a travel segment determination unit (15) determines a next travel segment which, forward in the travel direction of the vehicle, has a road slope different from that of the current travel segment where the vehicle is currently traveling. A next gear stage selection unit (16) determines a next gear stage, which will be the gear stage of a transmission in the next travel segment, on the basis of the speed of the vehicle, an equal fuel consumption map of the engine of the vehicle, and the travel resistance of the vehicle in the next travel segment estimated on the basis of the road slope in the next travel segment.

Abstract: A vehicle control device including: a road gradient acquisition unit configured to acquire a road gradient of a road on which a vehicle is currently traveling; a travel section determination unit configured to determine a forward travel section that is a travel section having a different road gradient from a current travel section in which the vehicle is currently traveling and that is ahead in a travel direction of the vehicle; and a horsepower limitation unit configured to limit an output horsepower of an engine based on a travel resistance of the vehicle, in which the horsepower limitation unit is configured to release the output horsepower limitation of the engine in a case where the travel resistance in the forward travel section is greater than the travel resistance of the vehicle in the current travel section.
