Abstract
Abstract Disclosed is an image processing apparatus having plural types of input devices (scanners, a still-video camera, a film scanner, etc.) for inputting image data. The type of input device which has entered the image data is identified, and an image judging processing method is decided from plural types of such methods based upon the type of input device identified. In accordance with the image judging processing method decided, the identity is judged between the image data inputted from the input device of the type identified and a specific image. <IMAGE>

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
80 words
An image processing apparatus comprising: first input means for inputting first image data representing a first image; second input means for inputting second image data representing a second image different from the first image, the second input means being independent of the first input means; discriminating means for discriminating whether the first or second image is a predetermined image; and processing means for processing the first or second image data in accordance with the discrimination result of the discriminating means.
Claim 2
Dependent Claim
27 words
An apparatus according to claim 1, wherein said discriminating means performs discriminating operation using a plurality of different standards for the first and second image data respectively.
Claim 3
Dependent Claim
23 words
An apparatus according to claim 2, further comprising memory means for storing a plurality of standard data relating to said plurality of standards.
Claim 4
Dependent Claim
31 words
An apparatus according to claim 1, wherein said first input means inputs color image data of which color characteristic is different from color image data input by said second input means.
Claim 5
Dependent Claim
28 words
An apparatus according to claim 1, further comprising third input means for inputting third image data representing a third image different from the first and second image data.
Claim 6
Dependent Claim
21 words
An apparatus according to claim 1, wherein said discriminating means comprises ROM for discriminating a color distribution of input image data.
Claim 7
Dependent Claim
36 words
An apparatus according to claim 1, further comprising processing means for adding a predetermined pattern to the first or second image when said discriminating means discriminates that the first or second image is said predetermined image.
Claim 8
Dependent Claim
87 words
A color processing apparatus comprising: first input means for inputting first color image data representing a first color image; second input means for inputting second color image data representing a second image different from the first color image, the second input means being independent of the first input means, discriminating means for discriminating whether the first or second color image is a predetermined color image; and processing means for processing the first or second color image data in accordance with the discrimination result of the discriminating means.
Claim 9
Dependent Claim
30 words
An apparatus according to claim 8, wherein said first input means inputs the first color image data frame-sequentially and said second input means inputs the second color image data dot-sequentially.
Claim 10
Dependent Claim
30 words
An apparatus according to claim 8, wherein said first input means inputs the first color image data serially and said second input means inputs the second color image data parallelly.
Claim 11
Dependent Claim
23 words
An apparatus according to claim 9, further comprising converting means for converting the frame-sequential first color image data to dot-sequential color image data.
Claim 12
Dependent Claim
23 words
An apparatus according to claim 10, further comprising converting means for converting the serial first color image data to parallel color image data.
Claim 13
Dependent Claim
46 words
An apparatus according to claim 9, wherein said first input means comprises a host computer and said second input means comprises an image reader which scans an original and generates data of a plurality of color components or a still video camera or a video camera.
Claim 14
Dependent Claim
13 words
An apparatus according to claim 11, wherein said converting means comprises a memory.
Claim 15
Dependent Claim
13 words
An apparatus according to claim 12, wherein said converting means comprises a memory.
Claim 16
Dependent Claim
31 words
An apparatus according to claim 8, further comprising third input means for inputting third color image data representing a third color image different from the first and second color image data.
Claim 17
Dependent Claim
21 words
An apparatus according to claim 8, wherein said discriminating means comprises ROM for discriminating a color distribution of input image data.
Claim 18
Dependent Claim
39 words
An apparatus according to claim 8, further comprising processing means for adding a predetermined pattern to the first or second color image when said discriminating means discriminates that the first or second color image is said predetermined color image.
Claim 19
Dependent Claim
91 words
An image processing apparatus comprising: input means for inputting color image data representing a color image in a plurality of types of color space; converting means for converting the color image data in a first type of color space to converted color image data in a second type of color space; discriminating means for discriminating whether the input color image is a predetermined color image based on the converted color image data; and processing means for processing the input color image data inaccordance with the discrimination result of the discriminating means.
Claim 20
Dependent Claim
34 words
An image processing apparatus according to claim 19, wherein said first type of color space is YMC or YMCK or L*a*b* color space and said second type of color space is RGB color space.
Claim 21
Dependent Claim
23 words
An image processing apparatus according to claim 19, wherein said discriminating means comprises ROM for discriminating a color distribution of input image data.
Claim 22
Dependent Claim
56 words
An image processing apparatus having input means for receiving input image data in a plurality of formats, and having discrimination means for discriminating whether the input image data represents a predetermined image, the discrimination means performing said discrimination in a manner appropriate to the format of input image data on which the discrimination is being performed.
Claim 23
Dependent Claim
51 words
An image processing apparatus having input means for receiving input image data in a plurality of formats, discrimination means for discriminating whether input image data represents a predetermined image, and means for converting input image data not in a predetermined format into the predetermined format for discrimination by the discrimination means.
