Abstract

PURPOSE:To suppress a memory capacity required for storing a picture data and to attain quick retrieval by storing a compressed picture data and a retrieval use low resolution image data for inputted picture data. CONSTITUTION:The memory capacity to store a compressed data is small enough in the method that A compressed data is stored in a memory, it is expanded into an image data but it is required to expand the data for each retrieval. Moreover, it is not required for data processing at the retrieval in the method that the image data is stored as it is in the memory and retrieved, but the memory capacity is increased because the image data is stored. Then an ID specific to the picture data and the image data with low resolution for retrieval and compressed data are stored in the memory as the picture data. The resolution of the image data for retrieval is decreased to a degree not giving hindrance to the retrieval and the compressed data is expanded when the picture is extracted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing device having a function of searching image data stored in a memory.

[Prior Art] In an image processing device that can display and search image data stored in a memory on a screen, there is a method for storing compressed data in a memory, decompressing it into image data that can be displayed on a screen, and searching it, and an image processing device that can display and search image data stored in a memory. There is a method of storing data as is in memory and searching it.

[Problems to be Solved by the Invention] The method of storing compressed data in a memory, decompressing it into image data, and searching requires less memory capacity because the compressed data is stored, but the data is There was a problem in that it required decompression and the search took time.

In addition, the method of storing image data as it is in memory and searching it requires less data processing at the time of retrieval, so the retrieval time is short, but the problem is that the memory capacity increases because the image data is stored. The dot went off.

[Means for Solving the Problems] The present invention reduces the memory capacity for storing image data and quickly stores low-resolution image data for retrieval in memory together with compressed data. This realizes an image processing device that can perform searches.

[Example] Embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the overall configuration of an image processing apparatus according to an embodiment of the present invention.

In the configuration shown, 1 is a microprocessor MP
U, performs calculations for image processing, logical judgments, etc.
Each component connected to the system bus SB is controlled via the system bus SB.

The system bus SB transfers address signals for instructing each component to be controlled by the MPUI, control signals for controlling each component, and data signals between each component.

Next, 2 is a read-only fixed memory ROM,
Fixed data such as a control procedure by the MPU 1, which will be described later with reference to FIG. 4, is stored.

3 is a writable random access memory RA
M, and is used for temporary storage of various data from each component.

Reference numeral 4 denotes an image storage buffer memory for storing image data.

Reference numeral 5 denotes an operation section, which includes various function keys such as a search key and a selection key for instructing various functions of the image processing apparatus.

Reference numeral 6 denotes an image input section, which includes an image reading device and the like, and captures image data.

Reference numeral 7 denotes an image output unit, which includes a display device, an external storage device, etc., and displays and stores image data.

FIG. 2 is an example of an image data storage method according to the present invention.

The memory stores an ID unique to each piece of image data, low-resolution image data for searching, and compressed data.

Since the image data for search has the resolution reduced as much as possible without interfering with the search, the storage capacity is much smaller than image data obtained by decompressing a compressed image.

When searching for an image, this low-resolution image data is used, and the compressed data is expanded and used only when the image is retrieved.

FIG. 3 is an example of an image search operation and screen display according to the present invention. Here, an example will be described in which five images A to H are stored in the memory.

First, enter the search key to enter search mode, and 3-1
As shown in , using the search image data, image A
-D four images are displayed. "1" to "4" are IDs assigned to each image AND, and "→" indicates that there is a next page. Further, by sequentially inputting the selection keys, screen displays shown in 3-1 to 3-7 are sequentially performed. Here, "O" represents blinking of the corresponding number/symbol.

In 3-1.3-6, when the search key is input, the image in the search mode can be retrieved as is, and the search mode is ended.

In steps 3-2 to 3-5, the image of the blinking ID can be retrieved by inputting the search key, and the search mode is ended. At this time, the compressed data corresponding to each ID is decompressed for the first time.

At 3-7, by entering the search key, the next page (3
-8) is displayed and the search mode for the next page is entered.

At 3-8, image E is displayed. "5" is image E
"-" indicates that there is a previous page. From here, by sequentially inputting the selection keys, the images shown in 3-8 to 3-10 are sequentially displayed. Furthermore, when the search key is input, the image in the search mode can be retrieved as is, and the search mode is ended.

At 3-9, enter the search key to return to the previous page (3
-1) is displayed, and the search mode for the previous page is entered.

At 3-10, the image of the blinking ID can be retrieved by inputting the search key, and the search mode is ended. At this time, the compressed data corresponding to each ID is decompressed for the first time.

FIG. 4 is a flowchart showing image search processing of the image processing apparatus according to the present invention.

In step 4-1, when a search key is input, a search mode is entered and the process proceeds to step 4-2.

In step 4-2, a search screen is displayed using the search image data, and the process proceeds to step 4-3.

In step 4-3, key input is performed, and step 4
-Proceed to 4.

In step 4-4, the type of key input in step 4-3 is determined, and if it is a selection key, step 3-2
Branch into. If a key other than the selection key, that is, a search key is input, the process branches to step 4-5.

In step 4-5, if the screen display in step 4-2 is in a blinking - (arrow) state, the process branches to step 4-2. Otherwise, the process branches to step 4-6.

In step 4-6, the search mode image or each I
The image data obtained by decompressing the compressed data corresponding to D is extracted, and the search mode is ended.

[Other Embodiments] In the above description, the case where a desired image is taken out has been described, but the case where the desired image is deleted from the memory will be described below.

FIG. 5 shows an example of the image search operation and screen display in this case. Here again, as in the case of Fig. 3, image A-
An example will be explained in which five images of H are stored in the memory. Also, 5-1 to 5-7 are 3-1 to 3, respectively.
Corresponds to -7.

In steps 5-2 to 5-6, the image with the blinking ID can be erased from the memory by inputting the erase key, new IDs are attached to the remaining images, and the search mode continues.

Further, in 5-1 and 5-7, the erase key is invalid.

[Effects of the Invention] As described above, in the image processing device according to the present invention, by storing low-resolution image data for retrieval along with compressed image data, the memory capacity required for storing image data can be suppressed, and This has the effect of allowing quick searches.
