Abstract
In an image capture apparatus that can perform processing using an image on which information displayed by a display device is superimposed and a method for controlling the same, the influence of the superimposed information included in the image is reduced. A first image in which information displayed by the display device is superimposed on an optical finder image is acquired. Then, the predetermined image processing is performed using a second image that excludes data on a pixel having the display color of the information, of pixels included in the first image.
Claims12
An image capture apparatus comprising,
- a finder optical system that includes an imaging surface of an image-capturing lens and a display device configured to transmit light forming an optical image and to display information;
- an acquiring unit configured to acquire a first image that is a combined image of the optical image formed on the imaging surface and the information displayed by the display device;
- and
- a processing unit configured to perform predetermined image processing using a second image that excludes data of a pixel having a display color of the information from pixels included in a predetermined area of the first image,
- wherein the predetermined image processing is subject detection processing or subject tracking processing that uses characteristic colors of pixels included in the second image, and
- wherein, when a difference between a position of the predetermined area and a position of the information in the first image is a predetermined value or more, the processing unit performs the predetermined image processing using an image that does not exclude data of a pixel having the display color of the information.
A method for controlling an image capture apparatus, wherein the image capture apparatus comprises a finder optical system including an imaging surface of an image-capturing lens and a display device configured to transmit light forming an optical image and to display information, the method comprising:
- acquiring a first image that is a combined image of the optical image formed on the imaging surface and the information displayed by the display device is superimposed;
- and
- performing predetermined image processing using a second image that excludes data of a pixel having a display color of the information, from pixels included in a predetermined area of the first image,
- wherein the predetermined image processing is subject detection processing or subject tracking processing that uses characteristic colors of pixels included in the second image, and
- wherein, when a difference between a position of the predetermined area and a position of the information is a predetermined value or more the performing performs the predetermined image processing using an image that does not exclude data of a pixel having the display color of the information.
An image capture apparatus comprising:
- a finder optical system that includes an imaging surface of an image-capturing lens and a display device configured to transmit light forming an optical image and to display information;
- an acquiring unit configured to acquire a first image that is a combined image of the optical image formed on the imaging surface and the information displayed by the display device;
- and
- a processing unit configured to generate a template image that excludes data of a pixel having a display color of the information from pixels included in a predetermined area of the first image and perform subject detection processing or subject tracking processing using the template image.
