Patent number: 8269866Abstract: An amplifier gain setting section estimates a light source parameter which relies upon a spectral distribution of an image pickup light source based on an image signal. Then, a first adjustment control value for each color signal when adjustment is to be performed so as to establish a white balance based on the estimated parameter is modulated by an amount corresponding to a follow-up sensitivity toward a second adjustment control value when adjustment is to be performed so that an achromatic subject under a particular reference light source is reproduced as an achromatic subject. The modulated adjustment control value is set to a white balance amplifier. The follow-up sensitivity is set to the amplifier gain setting section in response to an illuminance level estimated from a detection value of the brightness.Type: GrantFiled: September 15, 2010Date of Patent: September 18, 2012Assignee: Sony CorporationInventors: Koichiro Ishigami, Hideho Une, Yumi Sanaka, Naoya Katoh

Patent number: 7573507Abstract: A white balance controlling apparatus can discriminate a green subject under a light source of the sun and a white subject under a fluorescent light source without the addition of a new color filter. The maximum or average value of luminance at a first portion of an image signal for one frame or field which includes pixels discriminated as pixels of green under a light source of the sun or white under a fluorescent light source is compared with that at any other portion of the image signal. If the maximum or average value of luminance at the first portion is either lower or higher than that at the other portion, then it is estimated that either a light source of the sun or a fluorescent light source is used.Type: GrantFiled: May 10, 2006Date of Patent: August 11, 2009Assignee: Sony CorporationInventor: Hideho Une

Publication number: 20050280718Abstract: The present invention provides an image pickup apparatus capable of adjusting a white balance by adjusting a level of a chrominance signal constituting a color image. The apparatus includes gain setup means setting up a limit value for a gain value which adjusts a level of the chrominance signal; gain adjusting means having a black body locus, as data, which indicates a locus of a change in color temperature of a full radiator on a chromaticity coordinate and adjusting the gain value; and chrominance signal amplifying means amplifying the chrominance signal in accordance with the adjusted gain value. When amplifying a chrominance signal exceeding a predetermined level in accordance with the set-up limit value, the gain adjusting means causes the gain value of the chrominance signal amplifying means applied to the chrominance signal to translate parallel along the black body locus, and adjusts to a position of the set-up limit value.Type: ApplicationFiled: June 20, 2005Publication date: December 22, 2005Applicant: Sony CorporationInventor: Hideho Une
