Patent number: 11805326Abstract: An image processing apparatus obtains an image captured in an image capturing and sets a white balance recording mode for recording the image as a still image and a white balance display mode for displaying the image before being captured as the still image on a display. The apparatus controls white balance correction performed on the image captured in the image capturing. In a case where a first display mode that is included in the display mode is set, the apparatus sets an amount of a light source color that remains after the white balance correction is performed on the image before being captured as the still image in the first display mode to be larger than the amount of the light source color that remains after the white balance correction is performed on the still image in the recording mode.Type: GrantFiled: March 2, 2022Date of Patent: October 31, 2023Assignee: CANON KABUSHIKI KAISHAInventor: Mitsuaki Hattori

Patent number: 8976268Abstract: An image processing apparatus capable of properly synthesizing a strobe-illuminated image and non-strobe-illuminated images, irrespective of a condition for illuminating a photographic subject. A sensitivity of strobe emission photographing is set to be lower than a sensitivity of non-strobe emission photographing, and a strobe-illuminated image and plural sheets of non-strobe-illuminated images are continuously photographed with the set sensitivities. The strobe-illuminated image is gain-processed with a gain amount, and positional deviations of the plural sheets of non-strobe-illuminated images relative to the strobe-illuminated image are corrected. An averaged image obtained by synthesizing the gain-processed image and the images after the positional deviation correction is synthesized with the strobe-illuminated image, while taking account of amounts of strobe illumination in the strobe-illuminated image, thereby obtaining a synthesized image.Type: GrantFiled: March 15, 2013Date of Patent: March 10, 2015Assignee: Canon Kabushiki KaishaInventor: Mitsuaki Hattori

Patent number: 8687847Abstract: A parameter for each of a plurality of images captured in time series is computed based on information obtained from the image, and a normal reference image (an image captured before an image targeted for processing is stored). A degree of similarity between the image targeted for processing and the normal reference image is computed, and a parameter to be used in image processing applied to the image targeted for processing is computed by performing weighted addition such that a parameter computed from the normal reference image has a higher weight than a parameter computed from the image targeted for processing the higher the degree of similarity.Type: GrantFiled: November 29, 2011Date of Patent: April 1, 2014Assignee: Canon Kabushiki KaishaInventor: Mitsuaki Hattori

Patent number: 7623161Abstract: An image pickup apparatus which can carry out proper white balance adjustment even at the time of bounce flash shooting. A white balance adjusting circuit uses a first correction value calculated based on shot image data as a white balance correction value when it is detected that no light has been emitted from the light emitting device, and uses a second correction value for shooting with light emission as the white balance correction value when it is detected that light has been emitted from the light emitting device. The white balance adjusting circuit uses a third correction value different from the second correction value as the white balance correction value, when a white balance photography determining section detects that the bounce flash photography has been carried out.Type: GrantFiled: November 3, 2004Date of Patent: November 24, 2009Assignee: Canon Kabushiki KaishaInventor: Mitsuaki Hattori
