Patent number: 9615071Abstract: A camera tuning circuit has a first storage space, a second storage space and a controller. The first storage space stores a first reference camera correction setting for a reference camera module under a first color temperature. The second storage space stores a second reference camera correction setting for the reference camera module under a second color temperature, wherein the second color temperature is different from the first color temperature. The controller receives a default camera correction setting of a target camera module, the first reference camera correction setting, and the second reference camera correction setting, and generates a tuned camera correction setting for the target camera module according to the default camera correction setting, the first reference camera correction setting, and the second reference camera correction setting.Type: GrantFiled: June 10, 2014Date of Patent: April 4, 2017Assignee: MEDIATEK INC.Inventors: Chia-Ching Chen, Muge Wang, Chih-Ping Lin, Chia-Hui Kuo, Yu-Seng Tsai

Patent number: 8059204Abstract: An apparatus for adjusting image color saturation and a method for adjusting a saturation level of an original image data are provided. The image color saturation apparatus includes a first color over-saturation level calculating unit, a parameter adjusting unit, a saturation adjusting unit and a second color over-saturation level calculating unit. The apparatus for adjusting image color saturation detects the number of over-saturation pixels in an input image according to a predefined over-saturation area, and the number of over-saturation pixels in an adjusted output image. Thus, the parameter adjusting unit can dynamically adjust a saturation gain to maintain the frame consistency according to the number of the over-saturation pixels.Type: GrantFiled: June 5, 2007Date of Patent: November 15, 2011Assignee: Realtek Semiconductor Corp.Inventors: Chun-Hsing Hsieh, Chia-Hui Kuo
