Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
193 words
A multifunctional image processor for inputting image data and for performing various kinds of image processing such as a spatial convolution and a color image processing by use of programs in accordance with an external control signal, comprising a) image data distribute means (31) including a plurality of means (1011-1014) for respectively inputting gray-scale image data (7) and color image data (G, B, R) each constituting the image data, and b) parallel image data processing means (32) including a plurality of arithmetic means (341-343) for performing a parallel operation in accordance with the external control signal on the image data distributed from said image data distribution means (31), characterised in that said image data distribute means (31) further includes gray-scale image data delay means (102; 1031-1032) for delaying the gray-scale image data inputted to one of said input means (1011-1014) and for thereby generating a plurality of delayed gray-scale image data (Fb 0 ―F b―7 ; Fg 1 , Fg 2 ); and select means (1041-1044) for selecting the image data from the gray-scale image data, and delayed gray-scale image data, or the color image data in accordance with the external control signal.
Claim 2
Dependent Claim
193 words
A multifunctional image processor for inputting image data and for performing various kinds of image processing such as a spatial convolution and a color image processing by use of programs in accordance with an external control signal, comprising a) image data distribute means (31) including a plurality of means (1011-1014) for respectively inputting gray-scale image data (7) and color image data (G, B, R) each constituting the image data, and b) parallel image data processing means (32) including a plurality of arithmetic means (341-343) for performing a parallel operation in accordance with the external control signal on the image data distributed from said image data distribution means (31), characterised in that said image data distribute means (31) further includes gray-scale image data delay means (102; 1031-1032) for delaying the gray-scale image data inputted to one of said input means (1011-1014) and for thereby generating a plurality of delayed gray-scale image data (Fb 0 ―F b―7 ; Fg 1 , Fg 2 ); and select means (1041-1044) for selecting the image data from the gray-scale image data, and delayed gray-scale image data, or the color image data in accordance with the external control signal.
Claim 3
Dependent Claim
65 words
A multifunctional image processor according to Claim 1 wherein the image data to be inputted to said image data distribute mean (31) is supplied from an image memory (4) for storing the image data and includes the gray-scale image data constituted with gray-scale data (Fg) and binary data (Fb) and the color image data comprised of gray-scale data (Gg, Bg, Rg) and binary data (Gb).
Claim 4
Dependent Claim
124 words
A multifunctional image processor according to Claim 1 wherein said gray-scale image data delay means disposed in said image data distribute means (31) comprises: gray-scale data delay means (1031, 1032) for delaying gray-scale data of the gray-scale image data and for thereby generating a plurality of delayed gray-scale data; and binary data delay means (102) for delaying binary data obtained by converting said gray-scale image data and for thereby generating a plurality of delayed binary data, whereby said image data distribute means (31) selects the image data in accordance with the external control signal from the gray-scale image data comprised of the gray-scale data or binary data, the delayed gray-scale image data comprising delayed gray-scale data or delayed binary data, or color image data.
Claim 5
Dependent Claim
66 words
A multifunctional image processor according to Claim 1 wherein said external control signal is supplied from a control processor (1), said multifunctional image processor further comprises: control signal store means (37) for storing said external control signal, whereby the image data is selected by inputting a control signal from said control signal store means to said select means (1041-1044) of said image data distribute means (31).
Claim 6
Dependent Claim
99 words
A multifunctional image processor according to Claim 1 wherein said parallel image data processing means (32) comprises: a plurality of input ports (A, B) for inputting the image data distributed from said image data distribute means (31); and internal control means (AR, DR) for specifying an operation of the processing means (32) in accordance with the control signal supplied from said control processor (1), whereby the image data from said data input ports (A, B) are fed to the respective arithmetic means (341-343) and are subjected to a parallel operation by use of said internal control mean (AR, DR).
Claim 7
Dependent Claim
67 words
A multifunctional image processor according to Claim 1 wherein said select means (1041-1044) of said image data distribute means (31) each selects gray-scale data of the gray-scale image data and gray-scale data of the delayed gray-scale image data by use of a specified control signal, and a spatial convolution is thereby carried out by distributing the selected image data to said parallel image data processing means (32).
Claim 8
Dependent Claim
76 words
