Image retrieval method and apparatus wherein for retrieval of a plurality of images, a sub-image of each image is specified and extracted, reference data such as memo data related to each sub-image is stored, and the sub-image and the memo data related thereto are combined and outputted as desired, thereby simplifying the retrieval of the plurality of images. Specifically, a sub-image which is the most characteristic to each image is extracted and combined with a memo data to thereby provide a clear clue to the image extraction. The number of specified sub-images is freely increased without rewriting original image data stored in an image file and image retrievel is settled by using a memo image and a cutout sub-image both having a less amount of data than the entire image, so that applications to a storage medium which is not rewritable, for example, an optical disc can be ensured with high response image display.

摘要:
A retrieved image display method in an image file system in which image data records undergone a data compression and index records including positional information of the image data records are stored in a file medium. The method includes a first step to specify a partial region of a retrieved image to be displayed on a display screen, a second step to attain, based on positional information above included in an index record corresponding to the retrieved image, a recording position of an image date portion on the file medium corresponding to the partial region to be displayed and to partially read out image data from the image data record, and a third step to restore the compressed image data thus read out into the original image data and to display the restored image data on the display screen. In accordance with to the partial region specified in the first step, the operations of the second step and the third step are successively and repetitiously achieved for a plurality of retrieved images to thereby flip pages of the retrieved images on the display screen.
摘要:
A display control apparatus comprises area specifier, area determiner and signal selector. The area specifier specifies at least one area of a bit map memory. The area determiner determines whether the scan position on the bit map memory is in the specified area or not, and, according to the determination, controls the signal selector so as to send the output of the bit map memory directly or through a look-up table to a display unit. In a modification, the signal selector selects the signal to be sent to the display unit from among the outputs of different look-up tables.
摘要:
Main data records are recorded in a first area of a non-rewritable optical disk and index records used for retrieving the main data records are recorded in a second area. Each index record includes a code data to be used as an index, and a provisional order which is an order of the code data to be registered, occupying in the code data already registered in the second area. Prior to the data retrieval, the index records are sequentially read out of the second area of the optical disk, the latest index record first, and a sorted index table is prepared in parallel with the readout of the index records by referencing the provisional orders. The data record is retrieved by searching the designated index code data on the index table, reading out a pointer stored in the table in paired relation with the index code and reading out the main data record from the first area of the optical disk.
