  • Patent number: 9843737
    Abstract: The imaging device comprises: an imaging unit, a shooting processor, an exposure information setter, and an image processor. The imaging unit stores electric charges in response to an incident light for each frame, thereby outputting an image signal. The shooting processor controls storage times, during which the imaging unit stores the electric charges. The exposure information setter sets first exposure control information that controls brightness of a first image signal generated based on a first storage time and second exposure control information that controls brightness of a second image signal generated based on a second storage time. The image processor combines the first and the second image signal. In the case where the first exposure control information satisfies a given condition, the exposure information setter sets the first and the second exposure control information such that storage times corresponding to frames adjacent to each other become equal to each other.

  • Publication number: 20150281608
    Abstract: An imaging element includes a plurality of types of smaller array units, each of which is configured with a plurality of types of color filters arranged in three rows by three columns. The color filters includes a first color filter and a second color filter which has a spectral characteristic different from that of the first color filter. These smaller array units are arranged in two rows by two columns to configure a larger array unit. Then, the smaller array units are disposed such that a first centroid position coincides with a second centroid position, in the larger array unit. The first centroid is formed with pixels used in pixel addition processing for pixel information based on light transmitted through the first color filters. The second centroid is formed with pixels used in pixel addition processing for pixel information based on light transmitted through the second color filters.

  • Patent number: 8982250
    Abstract: An image processing apparatus is provided which minimizes reduction in S/N ratio and deterioration in resolution feeling at the lens periphery when the peripheral light amount drop correction of the lens is performed. An image processing LSI to perform the peripheral light amount drop correction of the imaging lens includes a space-direction noise removal correction part and a time-direction noise removal correction part. As the distance from the lens center position increases, the space-direction noise removal correction part reduces the noise reduction correction intensity to the image region to which the light amount drop correction gain is added in each image. As the distance from the lens center increases, the time-direction noise removal correction part increases the noise removal correction intensity to the image region to which the light amount drop correction gain is added in each image.

  • Patent number: 8721197
    Abstract: In a microcomputer included in an image device, a mask 2D 3D converting section expresses coordinates of a 2-dimensional image plane defined by an imaging element having a rectangular contour in a 3-dimensional coordinate system. The image plane is positioned in the state that a focal length corresponding to a zoom position is adopted as a Z coordinate value of the image plane in the 3-dimensional coordinate system. A mask display position calculating section 165 calculates a 2-dimensional position of a mask on a camera screen by utilizing a similarity of the size of the image plane and the size of the camera screen when a position of a mask on the image plane in the 3-dimensional coordinate system after PAN, TILT rotations and a zooming is converted into the 2-dimensional position of the mask on the camera screen.
