Abstract
Abstract In sequential processings of converting input picture data springs having unitary picture data in succession to picture data of a form adapted for displaying, storing the resultant picture data and then displaying the same in a display, a first detection data and a second detection data are monitored. The first detection data is indicative of commencement of the unitary picture data and is detected from the input picture data strings. The second detection data is indicative of termination of the conversion and is detected on the unitary picture data basis. If the second detection data has not been detected at the time when the first detection data has been detected, the unitary picture data detected with the first detection data is invalidated and the unitary picture data is left unprocessed. If the second detection data has been detected at the time when the first detection data has detected, the unitary picture data detected with the first detection data is transferred to a subsequent stage for implementing a subsequent processing with respect to the unitary picture data. As such, even if the picture data is inputted independently of a processing ability of a picture data processing apparatus, the data can be processed and outputted in conformity with the processing ability of the apparatus.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
281 words
An apparatus for processing continuously inputted picture data strings, each of the data strings being composed of successively occurring unitary picture data, and each of the unitary picture data having a commencement data indicative of commencement of the unitary picture data, said apparatus comprising: first detecting means for detecting said commencement data of each unitary picture data from said input picture data strings and providing a first detection data indicative of the detection of said commencement data; gate means for controlling transferring of said unitary picture data whose commencement data has been detected by said first detecting means; first memory means for temporarily storing said unitary picture data transferred by said gate means; arithmetic means for converting said unitary picture data stored in said memory means to a data of a form adapted for displaying and outputting the resultant data; second memory means for storing said data outputted from said arithmetic means; display means for displaying said data stored in said second memory means; second detecting means for detecting termination of a conversion of said unitary picture data by said arithmetic means and providing a second detection data indicative of the detection of the termination of the conversion; and control means responsive to said first detection data and said second detection data for controlling said gate means to operate such that said unitary data whose commencement data has been detected by said first detecting means is transferred through said gate means when said first detection data has occurred subsequent to an occurrence of said second detection data and is not transferred through said gate means when no second detection data has occurred prior to an occurrence of said first detection data.
Claim 2
Independent Claim
281 words
An apparatus for processing continuously inputted picture data strings, each of the data strings being composed of successively occurring unitary picture data, and each of the unitary picture data having a commencement data indicative of commencement of the unitary picture data, said apparatus comprising: first detecting means for detecting said commencement data of each unitary picture data from said input picture data strings and providing a first detection data indicative of the detection of said commencement data; gate means for controlling transferring of said unitary picture data whose commencement data has been detected by said first detecting means; first memory means for temporarily storing said unitary picture data transferred by said gate means; arithmetic means for converting said unitary picture data stored in said memory means to a data of a form adapted for displaying and outputting the resultant data; second memory means for storing said data outputted from said arithmetic means; display means for displaying said data stored in said second memory means; second detecting means for detecting termination of a conversion of said unitary picture data by said arithmetic means and providing a second detection data indicative of the detection of the termination of the conversion; and control means responsive to said first detection data and said second detection data for controlling said gate means to operate such that said unitary data whose commencement data has been detected by said first detecting means is transferred through said gate means when said first detection data has occurred subsequent to an occurrence of said second detection data and is not transferred through said gate means when no second detection data has occurred prior to an occurrence of said first detection data.
Claim 3
Dependent Claim
21 words
The apparatus according to claim 1, wherein said unitary picture data amounts to a single image plane of said display means.
Claim 4
Dependent Claim
79 words
The apparatus according to claim 1, wherein said unitary picture data amounts to a single line, and wherein when no second detection data has occurred prior to an occurrence of said first detection data, said control means controls said second memory means such that a one line preceding picture data which has been subjected to arithmetic operation by said arithmetic means id duplicated in said second memory means to provide the same data as the one line preceding data.
Claim 5
Dependent Claim
36 words
The apparatus according to claim 3, wherein said picture data is a string of runlength coded data in which color information representing a color and length information representing a length of the color information are coded.
Claim 6
Dependent Claim
48 words
The apparatus according to claim 1, wherein said picture data is a string of runlength coded data in which color information representing a color and length information representing a length of the color information are coded and said unitary picture data amounts to one said runlength coded data.
