Patent number: 10805553Abstract: According to one embodiment, an imaging apparatus includes an image sensor, image generation circuitry, calculation circuitry and superimposition circuitry. The image generation circuitry successively generates a first image and a second image. The calculation circuitry calculates a first parameter to allow brightness of the first image to be equal to or close to a predetermined value, and calculates a second parameter relating to brightness of the second image based on the first parameter and a predetermined ratio. The superimposition circuitry generates a composite image by superimposing the second image in which the brightness is adjusted using the second parameter onto the first image in which the brightness is adjusted using the first parameter.Type: GrantFiled: April 13, 2018Date of Patent: October 13, 2020Assignee: Canon Kabushiki KaishaInventors: Yuma Kudo, Junya Fukumoto, Takashi Tsuda
