A method and an apparatus are provided for capturing a moving image and a still image. Moving-image capturing is ceased, when a still image-capturing request is generated. Still-image capturing operation parameters are set in the image sensor. The image sensor is exposed to generate still-image data. Moving-image capturing operation parameters are set in the image sensor, when generation of the still-image data is complete. The image sensor is exposed to generate the moving-image data. The still-image data is quality-processed and compressed to generate still-image frame data. Moving-image frame data generated by quality-processing and size-adjusting the moving-image data are connected and compressed to generate a moving-image stream. Quality-processed virtual moving-image frame data is generated using the still-image data. The quality-processed virtual moving-image frame data is inserted into a loss section of the moving-image stream corresponding to a period in which the moving-image capturing is ceased.
