Abstract

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.

Claims

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, and the operation or an output destination of the image converter is specified or changed during operation by interpreting the instructions.

2. The image converting device according to claim 1,

wherein the image converter generates a plurality of images with respect to the input image data in the line memory.

3. 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.

4. The image converting device according to claim 1,

wherein the image converter reads the input image data from any position in the line memory.

5. The image converting device according to claim 4,

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.

6. The image converting device according to claim 5,

wherein the conversion specifier is programmed by a general-purpose computing unit.

7. The image converting device according to claim 6, further comprising:

a video-image display by which a plurality of conversion results with respect to one video-image input are output.

8. The image converting device according to claim 7,

wherein the conversion specifier describes correspondence between one region of the input image data and one region of the converted image data by triangle patches,

wherein bases of two or more of the triangle patches of an input side are aligned to form a strip-like shape, and

wherein two or more of the triangle patches of the converted image data have variable shapes.

9. An image converting system comprising two or more image converting devices, each of the image converting devices including an image input device, an image converter, and a line memory,

wherein the two or more image converting devices output conversion results to a storage medium common to each other while synchronizing with each other.

10. An image converting system comprising two or more image converting devices, each of the image converting devices including an image input device, an image converter, and a line memory,

wherein the image converting system further includes a video-image display, and

wherein the two or more image converting devices output conversion results to the video-image display while synchronizing with each other.
