Abstract
This invention makes it possible to execute photography with a sufficient red-eye relaxation effect. To do this, in this invention, the amount of a red eye is detected on the basis of a signal obtained by reading an object image under light projection by a light projection unit. The light projection by the light projection unit is controlled on the basis of the detection result.
Claims10
An image sensing apparatus, comprising:
- an image sensing unit;
- a light projection unit;
- an image acquisition unit that acquires sensed image data from the image sensing unit before a recording instruction is input by a user;
- a display unit that displays the sensed image data acquired by the image acquisition unit;
- a detection unit that detects a red-eye region in the sensed image data acquired by the image acquisition unit during light projection by the light projection unit;
- a switching unit that switches to one of displaying, on the display unit, an entire image of the sensed image data and displaying an enlarged image of a partial region within the sensed image data according to the red-eye region detected by the detection unit, wherein the enlarged image to be displayed on the display unit is an image to which a red-eye correction processing for the red-eye region is not applied and the display unit displays only one enlarged image at any given time;
- and
- a correction unit, wherein, after the recording instruction is input by a user and, in response to which the image acquisition unit acquires a photographed image, the correction unit executes red-eye correction processing on the photographed image in accordance with information from the detected red-eye region.
A method to control an image sensing apparatus, wherein the image sensing apparatus includes an image sensing unit, a light projection unit, an image acquisition unit, a display unit, a detection unit, a switching unit, and a correction unit, the method comprising:
- acquiring, using the image acquisition unit, sensed image data from the image sensing unit before a recording instruction is input by a user;
- displaying, on the display unit, the sensed image data acquired by the image acquisition unit;
- detecting, using the detection unit, a red-eye region in the sensed image data acquired by the image acquisition unit during light projection by the light projection unit;
- switching, using the switching unit, to one of displaying, on the display unit, an entire image of the sensed image data and displaying an enlarged image of a partial region within the sensed image data according to the red-eye region detected by the detection unit, wherein the enlarged image to be displayed on the display unit is an image to which a red-eye correction processing for the red-eye region is not applied and the display unit displays only one enlarged image at any given time;
- and
- after the recording instruction is input by a user and, in response to which the image acquisition unit acquires a photographed image, using the correction unit to execute red-eye correction processing on the photographed image in accordance with information from the detected red-eye region.
