Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
81 words
An image-taking system comprising: an objective body detecting means which detects an objective body from a taken image, a scene determining means which determines a scene of the image, and a parameter control means which controls a parameter to be used in detecting the objective body according to result of determination by the scene determining means, wherein the parameter control means changes the method of controlling the parameter according to a working stage in an image-taking mode of the image-taking system.
Claim 2
Dependent Claim
81 words
An image-taking system comprising: an objective body detecting means which detects an objective body from a taken image, a scene determining means which determines a scene of the image, and a parameter control means which controls a parameter to be used in detecting the objective body according to result of determination by the scene determining means, wherein the parameter control means changes the method of controlling the parameter according to a working stage in an image-taking mode of the image-taking system.
Claim 3
Dependent Claim
31 words
An image-taking system as defined in claim 1 , wherein the working stage in the image-taking mode includes at least one of a taking-through-image status, a taking-pre-image status, and a taking-running-image-status.
Claim 4
Dependent Claim
38 words
An image-taking system as defined in claim 2 in which the parameter is a gain in a gain correction used in the objective body detecting means or a detecting threshold value used in the objective body detecting means.
Claim 5
Dependent Claim
65 words
An image-taking system as defined in claim 3 , wherein, in case that the working stage has been changed from the taking-through-image status to the taking -pre-image status, the parameter control means controls the parameter used in detecting the objective body in the taking-pre-image status based on at least one of the result of the objective body detecting and the gain in the taking-through-image status.
Claim 6
Dependent Claim
65 words
An image-taking system as defined in claim 3 , wherein, in case that the working stage has been changed from the taking-through-image status to the taking -running-image status, the parameter control means controls the parameter used in detecting the objective body in the taking-running-image status based on at least one of the result of the objective body detection and the gain in the taking-through-image status.
Claim 7
Dependent Claim
66 words
An image-taking system as defined in claim 1 in which the objective body detecting means detects the objective body by detecting the objective body from the image by the use of a plurality of parameters of different values including the controlled parameter corrected by the parameter control means and taking as the result of objective body detection by integrating a plurality of the results of detection.
Claim 8
Dependent Claim
52 words
An image-taking system as defined in claim 1 in which the parameter includes one or more of a degree of contour correction in a contour correction, a degree of noise reduction in a noise reduction and a γ curve in a γ correction, which are employed in the objective body detecting means.
Claim 9
Dependent Claim
36 words
An image-taking system as defined in claim 1 , wherein an objective body is a face and the objective body detecting means detects the face after the scene determining means determines the scene of the image.
