Abstract

Abstract An image information processing apparatus includes an image memory having a page memory area for storing image information and a FIFO memory area which is provided integrally with the page memory and a read/write operation of which is controlled independently of the page memory area. Coded image information supplied from a recording unit is transferred to a codec circuit through the FIFO memory area and decoded by the codec circuit. The decoded information is stored in the page memory area.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 195 words
An image information processing apparatus comprising: image memory means for storing image information; codec means, connected to said image memory means, for coding the image information stored in said image memory means and decoding the image information read out from said image memory means; said image memory means including first-in first-out memory means, provided between said image memory means and said codec means, for sequentially storing the image information read out from said image memory means and sequentially supplying the image information to said codec means in a first-in first-out manner, and for sequentially storing the image information output from said codec means and transferring the image information to said image memory means in the first-in first-out manner; detecting means connected to said first-in first-out memory means, for detecting the storage state of said first-in first-out memory means; control means, connected to said detecting means and said first-in first-out means, for controlling the operation of said first-in first-out memory means in accordance with the storage state of said first-in first-out memory means; and buffer memory means, provided integrally with said first-in first-out memory means, for storing the decoded image information supplied from said codec means.
Claim 2
Dependent Claim 195 words
An image information processing apparatus comprising: image memory means for storing image information; codec means, connected to said image memory means, for coding the image information stored in said image memory means and decoding the image information read out from said image memory means; said image memory means including first-in first-out memory means, provided between said image memory means and said codec means, for sequentially storing the image information read out from said image memory means and sequentially supplying the image information to said codec means in a first-in first-out manner, and for sequentially storing the image information output from said codec means and transferring the image information to said image memory means in the first-in first-out manner; detecting means connected to said first-in first-out memory means, for detecting the storage state of said first-in first-out memory means; control means, connected to said detecting means and said first-in first-out means, for controlling the operation of said first-in first-out memory means in accordance with the storage state of said first-in first-out memory means; and buffer memory means, provided integrally with said first-in first-out memory means, for storing the decoded image information supplied from said codec means.
Claim 3
Dependent Claim 31 words
