Embodiment Construction

[0034] Hereinafter, an embodiment (first embodiment) of the present invention will be described in detail with reference to the drawings. Fig. 1 shows the overall structure of this embodiment. With reference to Fig. 1, the digital camera equipment of the first embodiment of the present invention comprises: CCD1, camera block 2, memory control block 3, display device 4, DRAM (Dynamic Random Access Memory) 5a and 5b, control block 6, operation input part 7, and external storage medium 8. The DRAMs 5a and 5b can be implemented with one DRAM having two memory areas.

[0035] The number of pixels (number of horizontal pixels×number of vertical pixels) of the CCD 1 is, for example, (1600×1280) for UXGA. Compared with the number of captured images (color images), the number of pixels of recorded images can be changed from SXGA (1280×1024), XGA (1024×768), VGA (640×480) and UXGA (1600× 1280) to choose from. The CCD 1 outputs the captured object image as a photographing signal via ...

Abstract

When an animation mode is designated, still picture data that has been photographed or discretely read from a record medium is compressed in a subtractive color process and a data compressing process corresponding to the LZW method. The compressed data is converted into an animation GIF file of which still picture data is combined in the time sequence and it is correlatively displayed on the time base. When an animation mode completion command is input or the size of the GIF file becomes a recordable size of the external storage medium 8, the GIF file data is written to the external storage medium 8. In addition, after a photographed still picture is recorded to the external storage medium 8, an animation can be created. In addition, an animation GIF file can be created using a plurality of still pictures recorded in the external storage medium 8. In addition, an animation GIF file that has been created can be edited.

Description

technical field [0001] The present invention relates to an imaging device and a signal processing method applicable to an image recording device such as a digital video camera for recording captured images in an external storage medium. Background technique [0002] Recently, digital imaging apparatuses that record an object image as image data to a recording medium such as a nonvolatile semiconductor memory device (eg, flash memory), a hard disk, or a floppy disk instead of recording it on a silver halide film have become popular. A digital camera converts a photographed target image into a digital image signal, compresses the converted digital image signal, and records the compressed image information onto a recording medium. [0003] A digital imaging apparatus employing a 3.5-inch floppy disk as a recording medium is portable because captured images can be easily input to a personal computer. In addition, certain digital cameras can record moving images. In this device...
