  • Patent number: 8749677
    Abstract: An imaging sensor has a pixel array in which pixels are disposed in a two-dimensional matrix state, a sampling part, a shutter control part, and a clipping circuit. A vertical signal line is coupled to the plurality of pixels disposed in a column direction, and to which a pixel signal is input from the pixels. The sampling part is coupled to the vertical signal line, and to which the pixel signal output to the vertical signal line is input. The clipping circuit is provided at an input side of the sampling part, and clips an electric potential of the vertical signal line to a first clip level before the pixel signal is input from the pixels to the vertical signal line when the shutter control part performs the global shutter operation. As a result, it is possible to stably operate the sampling part.

  • Patent number: 8698924
    Abstract: A technique is provided for generating sharp, well-exposed, color images from low-light images. A series of under-exposed images is acquired. A mean image is computed and a sum image is generated each based on the series of under-exposed images. Chrominance variables of pixels of the mean image are mapped to chrominance variables of pixels of the sum image. Chrominance values of pixels within the series of under-exposed images are replaced with chrominance values of the sum image. A set of sharp, well-exposed, color images is generated based on the series of under-exposed images with replaced chrominance values.

  • Patent number: 8497934
    Abstract: An actively addressable aperture disposed ahead of the rear surface of a camera lens allows the camera to capture a full-resolution, five-dimensional (5D) light field that describes every possible view from every possible angle of the scene being imaged. Shifting the aperture over the entire aperture plane and acquiring an image at each step yields a 2D grid of 2D images of the scene, otherwise known as a 4D parameterized light field. Estimating the 3D depth of the objects in the imaged scene yields a 3D model with 2D surface irradiance patterns, which is the full, non-parameterized 5D light field. The 5D light field can be used to display perspective changes in a way that mimics cognitive processing of the same scene or object. 5D light fields can also be used to create high-precision, 3D depth maps suitable for 3D movies, interactive displays, machine vision, and other applications.

  • Patent number: 8436935
    Abstract: In an image pickup device of the present invention, in the case where a mode switch 116 selects a finder mode, a focusing lens is driven at a first speed when a focusing operation is performed in a focus control unit 203. In the case where the mode switch 116 selects a live view mode, the driving speed of the focusing lens is switched in a range lower than the first speed in accordance with brightness of an object detected by a photometric unit 114 when the focusing operation is performed in the focus control unit 203. With such a configuration, a lens driving control method is changed by AF control of a phase difference detection system and AF control of a hill climbing system, and a driving system suitable for each AF system is performed, whereby the focusing operation can be performed normally at a high speed.

  • Patent number: 8411161
    Abstract: A method of and an apparatus for automatically estimating the tilting angle in tilted images enables level correction of the images. A preferred orientation of objects in an image and the deviation of the current orientation from the preferred orientation is determined by tilt image analysis without object recognition. Tilt image analysis includes several steps such as gradient feature computation, line segment tracking, line segment estimation and orientation deviation estimation. Once the tilt angle is determined, the image can be corrected so that an object or scene is not tilted or is tilted by only the appropriate amount.

  • Patent number: RE44924
    Abstract: A digital observation system and method for processing and transmitting video data between a video camera, or video cameras, and a base unit. The video data is transmitted, for example, by a communication protocol that is compliant with Ethernet physical drivers for transmitting and receiving data at around 100 Mbps. Video is captured at a sensor in the video camera, digitally processed and transmitted, thus overcoming limitations associated with analog processing and allowing unique features to be added. Images and other data may be transmitted efficiently in their native format, with reduced overhead, and in a non-compressed format due to the data transmission rate at or below 100 Mbps.
