An image recording apparatus comprising: an acquisition means (150) configured to acquire an image; a reduced image generation means (151) configured to generate a reduced image by reducing the number of pixels of the image acquired by the acquisition means; a memory (153, 174); a first cutout image generation means (173) configured to generate a first cutout image by cutting out a part of the image that is not reduced by the reduced image generation means; a recording processing means configured to perform, on the reduced image generated by the reduced image generation means, a recording process including image processing for recording involving the writing into the memory on the reduced image stored in the memory and processing for recording the processed reduced image into a storage means; a display control means (166 111) configured to perform control so as to present a first display by outputting an image based on the reduced image generated by the reduced image generation means and stored in the memory to a display means or an enlarged display by outputting an image based on a cutout image generated by the first cutout image generation means and stored in the memory to the display means during the recording process; a processing means (156 109, or 158, 160 (107, 108)) configured to perform specific processing different from the recording process and the display processing performed in the display means, the specific processing involving writing of data into the memory or reading of data from the memory; and a control means configured to perform control so as not to execute the specific processing when the enlarged display is being presented during the recording process and to perform control so as to execute the specific processing when not the enlarged display but the first display is being presented during the recording process. an acquisition means (150) configured to acquire an image; a reduced image generation means (151) configured to generate a reduced image by reducing the number of pixels of the image acquired by the acquisition means; a memory (153, 174); a first cutout image generation means (173) configured to generate a first cutout image by cutting out a part of the image that is not reduced by the reduced image generation means; a recording processing means configured to perform, on the reduced image generated by the reduced image generation means, a recording process including image processing for recording involving the writing into the memory on the reduced image stored in the memory and processing for recording the processed reduced image into a storage means; a display control means (166 111) configured to perform control so as to present a first display by outputting an image based on the reduced image generated by the reduced image generation means and stored in the memory to a display means or an enlarged display by outputting an image based on a cutout image generated by the first cutout image generation means and stored in the memory to the display means during the recording process; a processing means (156 109, or 158, 160 (107, 108)) configured to perform specific processing different from the recording process and the display processing performed in the display means, the specific processing involving writing of data into the memory or reading of data from the memory; and a control means configured to perform control so as not to execute the specific processing when the enlarged display is being presented during the recording process and to perform control so as to execute the specific processing when not the enlarged display but the first display is being presented during the recording process.
