Abstract

An information processing apparatus includes: an input device that inputs image data output from an electronic camera; a storage device that stores the input image data; and a control device that sets in advance save conditions under which the input image data are to be saved in the storage device and automatically saves the image data in conformance to the save conditions when the image data has been input.

Claims

1. A method of exchanging information related to a look-up table referenced in order to obtain a post-adjustment processing image data value corresponding to pre-adjustment processing image data value, comprising:

a step of exchanging at least control point information that is referenced when generating a characteristics curve for defining conversion characteristics of said look-up table through an interpolation operation.

2. An image input apparatus comprising:

an image processing device that performs image processing on an input image by referencing a look-up table;

a storage device that stores control point information that is referenced when generating a characteristics curve for defining conversion characteristics of said look-up table through an interpolation operation; and

a control device that inputs or outputs, at least, said control point information when there is an external request to input or output information related to said look-up table.

3. An information processing apparatus, comprising:

a look-up table generating device that generates a characteristics curve for defining conversion characteristics of a look-up table through an interpolation operation by using a plurality of control points; and

a control device that outputs, at least, information related to said control points when outputting information related to the look-up table to an image processing device which performs image processing on an input image by referencing the look-up table, and inputs, at least, the information related to said control points when inputting the information related to the look-up table from the image processing device.

4. An information processing apparatus according to claim 3, further comprising:

a display device that displays the characteristics curve of the look-up table generated by said look-up table generating device; and

an input device that takes in an instruction for a characteristics curve shape modification with regard to a characteristics curve displayed on said display device, wherein;

said look-up table generating device generates a characteristics curve of the look-up table for modification based upon the information related to said control points input from said image processing device;

said display device displays the characteristics curve of the look-up table for modification that has been generated;

said input device takes in an instruction for a characteristics curve shape modification with regard to the characteristics curve of the look-up table for modification; and

said control device outputs, a least, information related to control points of a modified characteristics curve when outputting information related to the look-up table having been modified in response to said instruction for a characteristics curve shape modification to the image processing device.

5. An information input system, comprising:

an image processing apparatus that generates a look-up table referenced to obtain a post-adjustment processing image data value corresponding to a pre-adjustment processing image data value; and

an image input apparatus that performs adjustment processing on image data obtained through an image input by referencing said look-up table, wherein;

said information processing apparatus outputs control point information that is referenced when generating a characteristics curve for defining conversion characteristics of said look-up table through an interpolation operation, together with data of said look-up table to said image input apparatus; and

said image input apparatus outputs, at least, said control point information among said look-up table data and said control point information to said information processing apparatus.

6. A recording medium that records therein a control program for an image input apparatus, said control program comprising:

an instruction for implementing image processing on an input image by referencing a look-up table; and

an instruction for inputting or outputting control point information that is referenced when generating a characteristics curve for defining conversion characteristics of said look-up table through an interpolation operation when there is an external request to input or output information related to said look-up table.

7. A data signal that transmits through a communication line and comprises a control program for an image input apparatus, said control program comprising:

an instruction for implementing image processing on an input image by referencing a look-up table; and

an instruction for inputting or outputting control point information that is referenced when generating a characteristics curve for defining conversion characteristics of said look-up table through an interpolation operation when there is an external request to input or output information related to said look-up table.

8. A recording medium that records therein a control program for an information processing apparatus, said control program comprising:

a look-up table generation instruction for generating a characteristics curve for defining conversion characteristics of a look-up table through an interpolation operation by using a plurality of control points;

an instruction for outputting, at least, information related to said control points when outputting information related to said look-up table to an image processing device that performs image processing on an input image by referencing said look-up table; and

an instruction for inputting, at least, the information related to said control points when inputting the information related to said look-up table from said image processing device.

9. A data signal that transmits through a communication line and comprises a control program for an information processing apparatus, said control program comprising:

a look-up table generation instruction for generating a characteristics curve for defining conversion characteristics of a look-up table through an interpolation operation by using a plurality of control points;

an instruction for outputting, at least, information related to said control points when outputting information related to said look-up table to an image processing device that performs image processing on an input image by referencing said look-up table; and

an instruction for inputting, at least, the information related to said control points when inputting the information related to said look-up table from said image processing device.
