Abstract: An electronic apparatus and an operation method of an electronic apparatus that can avoid erroneous detection of a touch panel in a case where a touch panel display unit is closed with respect to a specific surface are provided. An electronic apparatus includes a touch panel display unit that includes a touch panel and is opened and closed with respect to a specific surface of an electronic apparatus main body by rotating in a direction of separating the touch panel from the specific surface and a direction of bringing the touch panel close to the specific surface, and restricts a sensitivity of the touch panel in a case where the touch panel display unit is positioned in the range on the side opposite to the specific surface with respect to the first position in a rotation range of the touch panel display unit.

Abstract: An obstacle detecting unit detects whether an obstacle exists in an area surrounding a vehicle in the direction a camera installed on the vehicle is pointed. If the obstacle is determined to have a portion at a predetermined height above a road surface with which the vehicle may make initial contact when the vehicle moves toward the obstacle, a virtual projection surface is set to the height of the predicted contact portion and viewpoint conversion processing is performed so as to project pixels of an image captured by the camera onto the virtual projection plane. In this way, the height of the projection plane and the height of the predicted contact portion match each other and the distance between the predicted contact portion and the vehicle is accurately expressed on a bird's-eye view image resulting from the viewpoint conversion.

Abstract: The present invention provides an image processing device capable of enabling accurate recognition of a solid object present near a vehicle and displaying the solid object. The image processing device includes a viewpoint conversion unit for receiving data of images captured by at least one image capturing camera and generating a top view image, a solid object extraction unit for detecting a solid object from the data of the images captured by the at least one image capturing camera and extracting the solid object, a solid object image generation unit for generating a solid object image in accordance with the solid object extracted by the solid object extraction unit, and an image synthesis unit for synthesizing the solid object image generated by the solid object image generation unit with the top view image generated by the viewpoint conversion unit.

Abstract: An image display method for displaying a combined image by capturing images at areas surrounding a vehicle includes a) calculating a plurality of displacement vectors for a plurality of points taken on images captured by a plurality of cameras upon the application of a load that changes the attitude of a camera on the vehicle, and b) determining each image borderline between two adjacent images such that a difference in the directions of displacement vectors in the neighborhood of each image borderline between two adjacent images does not exceed a predetermined angle.

Abstract: An internal parameter storage unit stores, in advance, a plurality of sets of internal parameters each of which can be applied to correct a pixel position in a direction from an image principal point, i.e., a plurality of sets of internal parameters for accommodating errors of different magnitudes that occur in individual directions from an image principal point. An internal parameter selection unit selects a set of internal parameters from the plurality of sets of internal parameters stored in advance on the basis of the direction of a pixel position to be corrected from the image principal point, and a distortion-corrected image generator corrects distortion on the basis of the selected set of internal parameters, so that, even when a surface of a lens is not exactly parallel to a surface of an image pickup device, distortion is corrected more accurately.
