step 101: a plurality of original frame images are acquired. It should be noted that the smart phone mentioned in this embodiment has a photographing function, and the original frame image is an original image photographed by the smart phone.
Step 102: one original frame image for display is selected from the plurality of original frame images. Specifically, any one of a plurality of original frame images can be selected for immediate display. Preferably, in this embodiment, the first acquired original frame image is selected for immediate display.
Step 103: and displaying the selected original frame image for display. If the first original frame image acquired in step 102 is selected for display, step 103 may be executed in parallel with the subsequent acquisition of the original frame image to speed up the display of the image, and the user's shooting operation is fed back at the first time.
Step 104: and performing HDR processing on the obtained multiple original frame images to obtain a processed HDR image. The HDR processing method may be any one of the prior art.
Step 105: in step 104, after the HDR processing is completed and the HDR image is obtained, the HDR image is displayed to replace the original frame image previously displayed. Preferably, in this embodiment, when the HDR image after processing is displayed in place of the original frame image being displayed, the HDR image is replaced from one side of the original frame image currently displayed to the opposite side line by line or column by column in an erasure replacement display manner. By adopting the erasing and replacing display mode, the attention of the user can be reduced, the user feels in subjective feeling that the images displayed twice are the same image and are all the processed HDR images, and the sensory experience of the user is improved.
Because the photographing quality of the mobile phone is improved at present, the difference between the original frame image and the HDR image is not large in practice, and by the method provided by the embodiment, the HDR image can be replaced by the original frame image without being discovered by a user, so that the user can feel that the photographing response speed is improved quickly, and the user can view the final HDR image.
Step 106: normally, the selected original frame image is saved on the mobile phone because the image needs to be displayed. When the HDR image has been acquired, the original frame image for display may be selected to be deleted and the HDR image saved.
Of course, in other embodiments, step 105 may not be needed, i.e., the user may only be allowed to view the original frame image after taking a picture. After the user exits the photo display interface, since the HDR has been stored in place of the original frame image in step 106, the HDR image may be displayed when the user operates the mobile phone again to enter the album to display the corresponding photo.
The inventive concept of this embodiment is to display the original frame image, perform HDR processing on the original frame image, and then display the obtained HDR image in place of the original frame image. Therefore, the shooting operation is smoother and the processing speed is faster from the perspective of the user.
