Image converting device and image converting system
View Patent ↗Means which enables image conversion in which a plurality of conversion results can be output without once saving all of video-image data, which has been input from image-pickup means, in a storage medium is provided. A single line memory having a plurality of lines is used while switching the role thereof for a reading use by a video-image converting means and a use for inputting image data from the image-pickup means. The image converting means obtains an input image, which is in the line memory, and carries out conversion of the input image based on a conversion specifying means interpreted by an instruction decoder.
1. An image converting device comprising:
an image input device that obtains input image data;
an image converter that executes operation about image conversion in accordance with two or more instructions defining the operation;
a line memory used in transmission and reception of data between the image input device and the image converter; and
a conversion specifier that describes a corresponding relation between the input image data obtained into the line memory by the image input device and converted image data after conversion,
wherein
the conversion specifier is described by combining the instructions,
the operation or an output destination of the image converter is specified or changed during operation by interpreting the instructions,
the image converter generates a plurality of converted image data, different from each other, by executing different instructions with respect to the input image data in the line memory,
the conversion specifier describes correspondence between one region of the input image data and one region of the converted image data by triangle patches,
two or more of the triangle patches of an input side have a fixed vertical size and a base that is arranged along a horizontal line of the line memory so as to form a strip-like shape, and
two or more of the triangle patches of the converted image data have variable shapes.
2. The image converting device according to claim 1 , further comprising:
a synchronizer that synchronizes image input to the line memory with the image converter in accordance with a waiting instruction that specifies input wait of the image data input to the line memory,
wherein the waiting instruction is present as an instruction of the two or more instructions defining the operation.
3. The image converting device according to claim 1 , wherein the image converter reads the input image data from any position in the line memory.
4. The image converting device according to claim 3 ,
wherein two or more types of the conversion specifiers are disposed in a general-purpose storage medium, and
wherein one of the two or more types of the conversion specifiers in the general-purpose storage medium is selected for use.
5. The image converting device according to claim 4 , wherein the conversion specifier is programmed by a general-purpose computing unit.
6. The image converting device according to claim 5 , further comprising:
a video-image display by which a plurality of conversion results with respect to one video-image input are output.
