Patent number: 8614749Abstract: 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: December 29, 2011Date of Patent: December 24, 2013Assignee: Canon Kabushiki KaishaInventor: Kenji Takahashi

Patent number: 8553127Abstract: This invention can reduce the circuit scale by synthesizing OSD data to be superposed on a picture of each resolution by using common OSD data. According to this invention, a video resolution converter converts an HD (High Definition) video signal into an SD (Standard Definition) video signal such as an NTSC or PAL video signal. A memory controller receives a sync signal identical to an SD picture obtained by frequency-dividing an HD video signal, and a sync signal based on an SD video signal, and reads out OSD data (4 bits per pixel) from the memory on the basis of these sync signals. The OSD data read out on the basis of the SD video signal is synthesized with the SD video signal by an SD_OSD_MIX unit, and then output. The OSD data read out on the basis of the SD sync signal synchronized with the HD is multiplied by an integer by an OSD resolution converter, synthesized with an HD video signal by an HD_OSD_MIX unit, and then output.Type: GrantFiled: June 14, 2010Date of Patent: October 8, 2013Assignee: Canon Kabushiki KaishaInventor: Hiroya Miura

Patent number: 8355058Abstract: An image pickup apparatus capable of forming a corrected image which does not give a feeling of wrongness to a user. In the apparatus, an image pickup element photoelectrically converts an optical image to output the same as image data. A target correction value is calculated for correcting image quality degradation due to a lens unit, based on lens characteristic information and a status of the lens unit. A system controller sets a rate of change to stepwise make the current correction value closer to the target correction value, and repeatedly calculates the correction value according to the target correction value and the rate of change. The image data is corrected based on the repeatedly calculated correction value. The rate of change is changed depending on the relationship between a preceding value of the correction value calculated in the past and the target correction value.Type: GrantFiled: November 29, 2010Date of Patent: January 15, 2013Assignee: Canon Kabushiki KaishaInventor: Kunihiro Shirai
