  • Patent number: 8289411
    Abstract: An apparatus takes in a plurality of still image frames, to generate an interpolated image frame. Next, moving addition of the still image frame and an interpolated image frame is performed in time-axis direction, to generate a superimposed image frame. At this time, high spatial frequency components in the superimposed image frame are suppressed strongly as alienation of motion between the still image frames becomes larger. Movie is reproduced by sandwiching these superimposed image frames between the still image frames. As a result of this, the movie reproduction with smooth motion is made possible even from a group of the still images photographed by an electronics still camera and the like.

  • Publication number: 20110317039
    Abstract: An image pickup apparatus capable of improving a conversion speed of column parallel A/D converters, while preventing a gradation representation of image pickup signals from becoming rough. The image pickup apparatus includes a CMOS sensor having A/D converters provided on output sides of column amplifiers for respective columns of two-dimensionally arranged pixels. The A/D converters have a first operation mode in which they operate with a first number of conversion bits and at a first conversion speed and a second operation mode in which they operate with a second number of conversion bits and at a second conversion speed. A signal processing circuit adds together plural pieces of two-dimensionally arranged pixel data output from the A/D converter that operate in the second operation mode, thereby expanding the number of gradation bits of the pixel data from the second number of conversion bits.

  • Patent number: 8077226
    Abstract: A data processing apparatus includes a zoom circuit for displaying and a zoom circuit for recording. The zoom circuit for displaying performs a zoom process using a least square method or linear interpolation on image data from a YUV conversion circuit so as to create display image data. On an LCD monitor, an image based on the display image data thus created is displayed. Furthermore, the zoom circuit for recording performs a zoom process using spline interpolation or linear interpolation on image data from the YUV conversion circuit so as to create recording image data. The zoom process for recording is executed in parallel with the zoom process for displaying. The recording image data thus created is recorded in a recording medium.

  • Patent number: 8077225
    Abstract: An image pickup apparatus includes optical and electronic zooming units, and a controller configured to control an operation of the electronic zooming unit. When the first aspect ratio is selected, the controller operates the electronic zooming unit along with an operation of the optical zooming unit between a first zoom state and a second zoom state that is closer to a telephoto end than the first zoom state. When the second aspect ratio is selected, the controller does not operate the electronic zooming unit between the first zoom state and a third zoom state that is located between the first zoom state and the second zoom state, and operates the electronic zooming unit along with the operation of the optical zooming unit between the second zoom state and the third zoom state.

  • Publication number: 20110298952
    Abstract: The image capture device of this invention includes: an optical system for producing a subject image; an imager, which receives the subject image and outputs an image signal representing the subject image; and an image processing section for zooming in on, or out, a given image based on the image signal and in accordance with information about a zoom power specified, to generate a new image signal with the zoom power changed. Until the zoom power specified reaches a predetermined value, the processing section zooms in on the image by interpolating pixels so that degree of sharpness given to the image increases. If a value representing illuminance of the image is a predefined value or more and if the zoom power is the predetermined value or more, the processing section fixes the degree of sharpness given to the image.

  • Patent number: 8054345
    Abstract: A digital camera includes a memory, and pixel data cut out from the memory is subjected to ½ horizontal thinning processing by a ½ horizontal thinning circuit when a zooming magnification is equal to or larger than “2”, and the thinned pixel data is written to an image buffer. A zooming circuit performs zooming processing on the thinned pixel data stored in the image buffer. Here, when the zooming magnification is smaller than “2”, the zooming circuit performs the zooming processing on original pixel data being read from the memory and then stored in the image buffer.

  • Patent number: 8054344
    Abstract: A system and method for zooming an image. In the illustrative embodiment, the system includes a memory for receiving first and second frames of image data; a motion detector for detecting motion in said first or said second frame of image data; and an intelligent zoom system for zooming said first or said second image using a first or a second zoom method based on a detection of motion by said motion detector on a pixel by pixel basis. In the illustrative embodiment, the invention is scene-based, it works on a pixel by pixel basis to determine if a pixel is in motion. It performs motion related zoom for pixels that are affected by motion and conducts cross-field zoom for steady pixels to reduce motion artifacts in zoom mode. Motion may be determined by comparing frame-to-frame pixel value variations to fixed motion threshold(s) or by other algorithms. Independent-field zoom refers to using information from one input field to form a zoomed picture in one associated output field.
