Embodiment 1

[0101] In the first embodiment, the case where the input uncompressed image data is compressed and the compressed image data is transferred to the storage unit 3 via the system bus 6 for accumulation will be described.

[0102] Fig. 2 is a block diagram showing the configuration of main parts of the image information processing system of the first embodiment.

[0103] As shown in Figure 2, the image information processing system 11 connects image input components 1 such as a CCD camera and a CCD image sensor for inputting images, and a liquid crystal display device for displaying images through a system bus 6 as a bus for data transmission. Such as image display unit 2A, storage unit 3 for accumulating image data, communication unit 4 for transmitting and receiving image data, and system control unit 5 for controlling each unit of the image information processing system 11.

[0104] Since the image compression section 1a is built in the image input section 1, the compressed im...

Embodiment 2

[0112] In the second embodiment, the case where the stored compressed image data is decompressed by the image decompression means via the system bus 6 and then reproduced and displayed will be described.

[0113] Fig. 3 is a block diagram showing the configuration of main parts of the image information processing system of the second embodiment.

[0114] As shown in Figure 3, the image information processing system 12 connects image input components 1A such as a CCD camera and a CCD image sensor for inputting images, and a liquid crystal display device for displaying images through a system bus 6 as a bus for data transmission. Such as image display unit 2, storage unit 3 for accumulating image data, communication unit 4 for transmitting and receiving image data, and system control unit 5 for controlling each unit of the image information processing system 12.

[0115] Since the image decompression unit 2a is built in the image display unit 2, the compressed image data can be ...

Embodiment 3

[0121] In the present embodiment 3, carry out data compression to the input non-compressed image data, the compressed image data that has been data compressed is transmitted to the storage unit 3 for storage via the system bus 6, and the stored compressed image data The case where data is decompressed by the image decompression means via the system bus 6 and reproduced and displayed will be described.

[0122] Figure 4 It is a block diagram showing the configuration of main parts of the image information processing system of the third embodiment.

[0123] like Figure 4 As shown, the image information processing system 13 is connected to image input components 1 such as a CCD camera and a CCD image sensor for inputting an image, and an image display device such as a liquid crystal display device for displaying an image through a system bus 6 as a bus for data transmission. A display unit 2, a storage unit 3 for accumulating image data, and a system control unit 5 for contro...

Abstract

An image information processing system is provided, which comprises an image input section for receiving image data, a storage section for storing the image data, and a control section for controlling the image input section and the storage section. The image input section, the storage section and the control section are connected together via a data transfer bus line. An image compression section for compressing the image data is provided within or adjacent to the image input section. The control section controls the image compression section to compress non-compressed image data input from the image input section, transfers the compressed image data via the data transfer bus line to the storage section, and controls the storage section to store the compressed image data.

Description

technical field [0001] The invention relates to an image information processing system and an image information processing method for inputting, outputting (displaying), accumulating (storing), sending and receiving etc. of still images and moving images, and particularly relates to portable telephone devices, portable information Terminal devices (PDAs), digital still cameras, mobile personal computers, etc. are mainly suitable for image information processing systems and image information processing methods of portable electronic devices that are used outdoors and require low power consumption. Background technique [0002] Conventionally, in such an image information processing system, image data input from image input components such as a CCD camera and a CCD image sensor are not compressed, but are transmitted to a ROM, etc. via a bus for data transmission. storage parts. Image data is compressed by an arithmetic processing unit such as a central processing unit (CPU) ...
