Problems solved by technology

[0012] However, in the aforementioned conventional resolution correction device 9, after the horizontal variable amplifier 94 emphasizes the horizontal outline of the image, the vertical variable amplifier 98 emphasizes the vertical outline of the image. In the circle, the correction amount is not the same
Therefore, there is a problem that a uniform resolution cannot be obtained in an image and a corrected image appears unnatural

Embodiment Construction

[0031] figure 1 is a block diagram of a resolution correction device according to an embodiment of the present invention. The resolution correction device 1 corrects the resolution of an image captured by a solid-state imaging element such as a CCD or a CMOS sensor. The resolution correction device 1 comprises an input T. An input terminal T receives an image signal S1 representing an image captured by a solid-state imaging element such as a CCD or a CMOS sensor. The image signal S1 input to the input terminal T is supplied to a horizontal contour signal generator 12 and a vertical contour signal generator 13 provided in the contour signal generator 11, and a contour correction signal adder 19.

[0032] The horizontal contour signal generator 12 generates a horizontal contour signal by extracting a horizontal contour component from the image signal S1, and outputs the horizontal contour signal S2 to a horizontal contour correction signal generator 17 provided in the contour...

Abstract

A resolution correction apparatus of the present invention includes: an outline signal generator for generating an outline signal, which represents an outline of an image, based on an image signal; an outline correction signal generator for generating an outline correction signal to emphasize the outline of the image, based on the outline signal generated by the outline signal generator and an amount of correction which is increased along radial directions from the center of the image to peripheral portions thereof; and an outline correction signal adder for adding the outline correction signal generated by the outline correction signal generator to the image signal.

Description

technical field [0001] The present invention relates to a resolution correction device and a program for correcting the resolution of an image captured by a camera used in a portable device, ie, an electronic still camera, etc., and to a computer readable recording medium having the same program recorded thereon. Background technique [0002] Cameras used in small portable devices, ie, electronic still cameras, are becoming smaller in size. A lens provided in such a camera has its own unique lens aberration and is characterized in that the resolution of an image captured by a camera incorporating such a lens is lower in the peripheral portion of the image than in the central portion of the image. A camera having such a lens captures an unclear image because the resolution of the image is lower in the peripheral portion of the image than in the central portion corresponding to the center of the lens. [0003] When the number of lenses is increased in order to prevent a decre...
