Patent number: 8106958Abstract: An evaluation value for a pixel in an eye region in an image is computed, which is increased with increase in the redness of the pixel and with decrease in the luminance of the pixel. Furthermore, a color saturation value for the pixel included in the eye region is corrected with the use of a luminance value for a surrounding region around an eye and the evaluation value. In this case, the color saturation value is corrected such that the amount of correction is smaller in a case in which the luminance value is smaller even with the same evaluation value, thereby achieving improvement in the correction factor of and prevention of false corrections of a redeye region with a low color saturation and a low luminance.Type: GrantFiled: January 5, 2009Date of Patent: January 31, 2012Assignee: Canon Kabushiki KaishaInventor: Kenji Takahashi

Patent number: 8063950Abstract: An imaging apparatus with an automatic adjustment function, such as a white balance adjustment function, enables a result of such adjustment to be checked easily using a vector display. A waveform generation unit 3 generates a vector signal from a video signal in response to an operation to push a switch unit 6 for automatic adjustment of white balance etc., and outputs the vector signal for a predetermined period. A synthesized signal generation unit 4 combines (superimposes) the video signal with (on) the vector signal and displays the synthesized signal on a display unit 5. A vector display superimposed on a video is performed on the display unit 5 for the predetermined period after the switch is pushed. This enables an adjustment result of white balance etc. to be checked easily without requiring other operations. The vector display is stopped automatically after the predetermined period, and thus does not disturb an imaging operation.Type: GrantFiled: January 5, 2009Date of Patent: November 22, 2011Assignee: Panasonic CorporationInventor: Hiroshi Shirahama

Patent number: 8054344Abstract: 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.Type: GrantFiled: June 16, 2006Date of Patent: November 8, 2011Assignee: Raytheon CompanyInventors: Frank N.

Patent number: 8054334Abstract: An imaging apparatus and an imaging method supply an optimum amount of image data to another apparatus. When a PDA has a maximum transfer rate of 1.5 Mbps, a mobile phone determines that the maximum speed of communication with the PDA is low, reduces the amount of moving image data captured by a CCD of the mobile phone accordingly, and supplies the captured moving image data to the PDA. The PDA therefore displays a low-quality moving image on its display unit. When the PDA has a maximum transfer rate of 480 Mbps, the CPU of the mobile phone leaves unchanged the amount of moving picture data captured by the CCD and supplies the captured moving image data to the PDA. The PDA then displays a high-quality moving image on its display unit. The foregoing may be advantageously applied to digital cameras.Type: GrantFiled: November 12, 2008Date of Patent: November 8, 2011Assignee: Sony CorporationInventors: Chisato Yoshida, Osamu Date

Patent number: 8004584Abstract: A user captures a digital image, which is then selected for post-processing within the image capture device. The image capture device decompresses the full size image, and buffers any metadata associated with the image. As a user applies each post-processing effect to the image, effect parameters are added to the metadata for the image. Upon completion of post-processing the effect parameters from the metadata are stored in a separate custom effect file. The image capture device then is able to perform the series of effects upon subsequent images after reading the effect parameters from the custom effect file.Type: GrantFiled: April 29, 2005Date of Patent: August 23, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Murray D.

Patent number: 7990446Abstract: A pixel cell with increased dynamic range is formed by providing a floating diffusion region having a variable capacitance, controlled by at least one gate having source and drain regions commonly connected to the floating diffusion region. The gate has an intrinsic capacitance which, when the gate is activated, is added to the capacitance of the floating diffusion region, providing a low conversion gain readout. When the gate is off, the floating diffusion region capacitance is minimized, providing a high conversion gain readout. The gate may also be selectively switched to mid-level. At mid-level, a mid-level conversion gain, which is between the high and low conversion gains, readout is provided, but the gate still provides some capacitance to prevent the floating diffusion region from saturating.Type: GrantFiled: June 19, 2006Date of Patent: August 2, 2011Assignee: Aptina Imaging CorporationInventor: Christian Boemler
