Description

BACKGROUND OF THE INVENTION Field of invention The present invention relates to an information processing device, a control method for the device and a program. Description of the related technique In recent years, resolutions and frame rates for moving image data used in video production have increased, and the amount of data is also constantly growing. A powerful playback device (and especially its processor) is required to smoothly play back such large amounts of moving images while image processing, such as decoding and demosaicing, is performed on each frame. In other words, a device without such processing capabilities will struggle to play videos smoothly. One way to address this issue is to run high-load image processing in the background before playback starts and temporarily store the processing results. This allows for simply reading and displaying the processing results after playback begins, ensuring smooth video playback. However, if playback is initiated before the processing results for all frames are stored, some frames will need to be reprocessed before being displayed, causing a sudden and dramatic drop in playback speed and resulting in an unnatural feel for the user. To avoid this, it's conceivable to display the processing progress before playback, prompting the user to wait until processing for their desired area is complete. However, if the storage space for the results is limited, it will not be possible to store the processing results for all frames in the video, regardless of how long the user waits. The user cannot know whether the desired section can be played back smoothly until the stored processing results reach the storage limit. In particular, if the data size of the processing results varies depending on the image processing parameters, the number of frames for which the processing results can be stored will also vary depending on these parameters. A recording device typically calculates and displays the number of still images, the duration of moving images, and the like that can be recorded based on the remaining space in the media. (Japanese patent disclosure) JP 2007 110 221 A For example, it proposes a method in which the duration of moving images that can be recorded is calculated based on the space remaining in the storage media, and if the duration is less than or equal to a defined value, image processing parameters are automatically changed so that longer moving images can be recorded, or an image quality setting screen is displayed to prompt the user to reconfigure the parameters. Similarly, in a playback device, the number of images for which processing results can be stored can be calculated based on the remaining memory space. However, if the moving image the user wishes to play back is sufficiently short and consists of only a small number of frames, it is not always necessary to change the parameters to reduce the amount of data. The total length of the moving image is already known, and therefore a more visual display is possible. Out of JP 2015 195 571 A A control method for an imaging device is known. During photography, image data generated from RAW image data through simple development processing is recorded along with the RAW image data. Subsequently, image data is generated from the RAW image data through high-quality development processing to replace the simply developed image data. By displaying information representing the progress of the high-quality development processing in conjunction with the image, the selection of the processing method is enabled based on this progress. SUMMARY OF THE INVENTION The present invention enables an improvement in user-friendliness by storing images obtained from a development process in memory and clearly displaying an area to a user that can be smoothly reproduced. According to one embodiment of the invention, an information processing device is provided which is configured to execute a playback process on a RAW moving image, wherein the device comprises an image processing unit for generating a processed moving image by performing image processing on the RAW moving image, which includes a development process, a memory for storing the processed moving image generated by the image processing unit, and a display control unit for performing control such that a bar corresponding to the length of a time axis of the RAW moving image is displayed on a display unit, wherein the display control unit is configured to display a processable area, which represents an area for which the moving image of the RAW moving image subjected to image processing by the image processing unit can be stored in memory, together with the bar, before the image processing of the RAW moving image is completed in this processable area. According to the invention, images obtained from a development process can be stored in memory to clearly show a user an area that can be smoothly reproduced, which in turn allows the user to confirm in advance w
