Description

  The present invention relates to an apparatus that captures and stores a still image and performs confirmation display of a captured image before storage.

  If the device style is changed when the confirmation image is displayed after taking a still image, and if image correction processing is performed on the captured image data at that time, enlargement to create a confirmation image for the changed style It was necessary to wait for the reduction process to complete the image correction process.

In related apparatuses, confirmation image display, image correction processing, and encoding at the time of still image shooting are performed, for example, according to the following procedure.
1. Capture internal image data.
2. The captured image data is enlarged / reduced to the confirmation image display size of the current style and displayed on the screen.
3. Image correction processing is performed on the captured image data.
4). The captured image data that has undergone image correction processing is encoded and stored.

  In an apparatus equipped with a related camera, since the display style of the apparatus is only one, the enlargement / reduction processing of the captured image data performed at the time of confirmation display before storage is once. However, as represented by recent mobile phones, there are a plurality of display styles.

As a related technique, a technique capable of confirming a photographed image after photographing at high speed has been proposed. The image data read out from the memory by the memory control circuit and the image processing circuit when the image data read from the image sensor is temporarily stored in the memory and displayed on the image display unit before image recording. Is reduced, and a quick review development process is performed and displayed on the image display unit (see, for example, Patent Document 1).

However, in the related art described above, when the user changes the device style, the captured image data needs to be enlarged or reduced to the confirmation image display size that matches the changed style. When the image correction process is in progress, the enlargement / reduction process for creating the confirmation image cannot be performed.
In order to save internal memory, the image correction process may be performed in the same memory area. In this case, if the enlargement / reduction process is performed, the correction process is completed halfway, but the correction process is not completed thereafter. This is because the image is enlarged or reduced.
For this reason, the photographed image data is enlarged / reduced to a confirmation image display size adapted to the changed style. It was necessary to wait for the image correction process to be completed.

  The present invention was made in order to solve the above-described problems, and in an apparatus for confirming and displaying a captured image before capturing and storing a still image and storing the image, the captured image is displayed immediately after shooting. An object of the present invention is to provide an imaging apparatus, an information processing apparatus, and a confirmation display image creation method capable of displaying a confirmation image at high speed when the apparatus style is changed.

Imaging apparatus of the present invention, have a row to confirm display of the still image shooting and storing and previously saved captured image, it performs scaling processing on the captured image, the image correction processing and coding on the captured image The enlargement / reduction process, the image correction process, and the encoding process are executed on the same memory, and the captured image while the image correction process and the encoding process are being executed is performed on the captured image. In an imaging device that cannot execute enlargement / reduction processing ,
After capturing the internal memory captured image data from the camera, prior to performing the image correction process and the encoding process to perform the scaling processing on the size that may be used in the confirmation display Features.

Also, check display image generating method of the present invention, have rows confirmation display of the captured image before photographing and saving and storage of still image, performs scaling processing on the captured image, the image relative to the captured image Correction processing and encoding processing are performed, and the enlargement / reduction processing, the image correction processing, and the encoding processing are executed on the same memory, and the imaging while the image correction processing and the encoding processing are executed A confirmation display image creation method in an imaging device that cannot perform the enlargement / reduction processing on an image,
After capturing the internal memory captured image data from the camera, prior to performing the image correction process and the encoding process to perform the scaling processing on the size that may be used in the confirmation display Features.

  According to the present invention, in an apparatus that displays and confirms a captured image before capturing / saving and storing a still image, the captured image is displayed immediately after shooting, but when the apparatus style is changed at that time, high-speed confirmation is performed. Images can be displayed.

  Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. The imaging device in the present embodiment shown in FIG. 1 has a configuration for two styles as an example.

  Referring to FIG. 1, the imaging apparatus according to the present embodiment includes a camera 100 that captures still images and outputs captured image data to a memory, a memory 101 that stores captured image data, and an enlargement to a confirmation image size. Enlargement / reduction processing units 102 and 106 that perform reduction processing, internal memories 103 and 107 that store image data of a confirmation image size, a switch 104 that determines which size of a confirmation image to display, and an image that displays an image The display unit 105 includes an image correction processing unit 108 that performs an image correction process on captured image data, and an encoding / storing unit 109 that encodes and stores the image correction processed data.

  Next, the operation of the present embodiment will be described in detail with reference to the drawings.

  First, image data captured by the camera 100 is stored in the memory 101 (S201).

  Thereafter, the enlargement / reduction processing unit 102 performs enlargement / reduction to the confirmation image size according to the current device style (S202), and stores the enlarged / reduced image in the memory 103 (S203). Is displayed on the image display unit 105 via the switch 104 (S204).

Next, confirmation images for the remaining styles are created (S205). The image stored in the memory 101 is reduced to a confirmation image size matching the remaining style using the enlargement / reduction processing unit 106 (S206), and the image after enlargement / reduction is stored in the memory 107 (S207).
Here, the confirmation images for the remaining styles are created after displaying the confirmation image having a size that matches the current device style, because the confirmation images are displayed quickly and the user is not given a waiting time.

  When a style change by the user occurs, the switch 104 is switched to display a confirmation image having a size suitable for the style (S208).

  Next, image correction processing and encoding storage of the captured image data are performed using the image correction processing unit 108 and the encoding / storage unit 109 (S209).

  In order to save internal memory, the image correction process may be performed in the same memory area. In this case, the image being processed cannot be read and the enlargement / reduction process cannot be performed. In this case, the correction process has been completed halfway, but the image that has not been corrected yet is enlarged or reduced thereafter. For this reason, confirmation images for the remaining styles other than the current style are created before image correction processing is performed on the captured image data.

  According to the above-described embodiment, after taking captured image data from the camera to the internal memory, before performing the image correction process and the encoding process, the size may be used for the confirmation display. By processing, no waiting time is generated at the time of style change.

  In addition, by performing enlargement / reduction for the style at the time of shooting and display of the confirmation image, enlargement / reduction for the remaining styles does not change the time taken to display the confirmation image, so a waiting time is added to the user. It will not be generated.

  As another embodiment, there is an example in which an image for all display styles is created in advance even when a JPEG image or the like is decoded and displayed inside the apparatus. In this example, when the terminal style is changed, the image is not resized to the size for the style but a display size image for all styles is created after decoding.

  The above-described embodiment is a preferred embodiment of the present invention, and various modifications can be made without departing from the gist of the present invention. For example, processing for realizing the function of the apparatus may be performed by causing the apparatus to read and execute a program for realizing the function of the apparatus. Further, the program is transmitted to another computer system by a transmission wave via a computer-readable recording medium such as a CD-ROM or a magneto-optical disk, or via a transmission medium such as the Internet or a telephone line. Also good.

It is a figure which shows the apparatus structure which concerns on embodiment of this invention. It is a flowchart which shows the operation | movement of the whole apparatus which concerns on embodiment of this invention.
