Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an electronic apparatus capable of outputting a plurality of images and capable of outputting a part of an input image. Description of the Related Art A crop function for extracting a region of a part of an input image from the input image (clipping, cropping) and outputting the region has been known. The region to be extracted can be changed, and hence the composition and angle of view of an output image can be changed without performing pan operation, tilt operation, and zoom operation of a camera. Japanese Patent Application Publication No. 2005-175683 discloses a digital camera for acquiring images in a plurality of regions of a taken image in response to pressing of a shutter button. An electronic apparatus that performs live streaming of video may output a first region, which is a region of a part of input video, for live streaming and also output a second region for archive that includes the first region simultaneously. For example, when the composition of live-streamed video (video in the first region that has been set for live streaming) was not optimal, video for archive (video in the second region) is useful for archive streaming and disc creation by resetting the region through post processing. The use of the first region that has been set for live streaming as a start point enables an appropriate region to be reset efficiently, and hence it is preferred that the first region can be easily grasped. SUMMARY OF THE INVENTION The present invention provides a technique to easily grasp a first region from image data on a second region that includes the first region. For example, the present invention provides a technique to easily grasp a region that is set for live streaming from video data for archive and enable a preferable region to be set efficiently by using the region as a start point. An electronic apparatus according to the present invention includes at least one memory and at least one processor which function as: an acquisition unit configured to acquire input image data; a first output unit configured to output image data on a first region which is a region of a part of the input image data; and a second output unit configured to output image data on a second region that includes the first region, wherein the second output unit outputs information indicating the first region together with the image data on the second region. Further features of the present invention will become apparent from the following description of exemplary embodiments with reference to the attached drawings.

DESCRIPTION OF THE EMBODIMENTS Embodiments of the present invention are described below. FIG. 1 is a block diagram illustrating a configuration of a camera 10 as an example of an electronic apparatus to which the present invention is applicable. A housing 100 houses a large number of components of the camera 10 therein. A lens 101 includes a focus mechanism, a zoom mechanism, a diaphragm, and an anti-shaking mechanism, and performs lens control, such as focus lens driving, diaphragm driving, and anti-shaking lens driving, on the basis of control commands received from a system control unit 110. The lens 101 may be incorporated in the housing 100, or may be an external lens mounted to the housing 100 through a lens mount (not shown). An imaging unit 102 includes an imaging sensor for converting an optical image condensed by the lens 101 into an electric signal and an A/D converter for converting an analog signal into a digital signal. The imaging sensor takes images at a predetermined frame rate. A video processing unit 103 acquires video data (input video data, moving image data) from the imaging unit 102 or a video input unit 126 at a predetermined frame rate. The video processing unit 103 performs video processing (image processing), such as resize processing, trimming processing, color conversion processing, and distortion correction processing, on the acquired video data, and stores the video data after the video processing into a memory 109 through a memory control unit 108. The video processing unit 103 may store video data (for example, RAW data) before image processing into the memory 109 as it is. The video processing unit 103 can use video data output from the imaging unit 102 (video data obtained by imaging) to perform predetermined arithmetic processing. The system control unit 110 p
