  • Publication number: 20120224766
    Abstract: An image processing apparatus includes a superimposition processing unit which performs a blend process on a plurality of images which are continuously photographed. The superimposition processing unit includes a moving subject detection unit, a blend processing unit, and a noise reduction processing unit. The moving subject detection unit detects the moving subject region of an image, and generates moving subject information in units of an image region. The blend processing unit generates a superimposition image by performing a blend process on the plurality of images using a high blend ratio in a stationary subject region and using a low blend ratio in the moving subject region based on the moving subject information. The noise reduction processing unit performs a stronger pixel value smoothing process on the moving subject region of the superimposition image based on the moving subject information.

  • Patent number: 8199229
    Abstract: A color filter allows a light signal to pass through by each pixel and be incident on an imaging device. The light signal is inputted through a lens and including one of plural different spectral components. The plural different spectral components include a first spectral component which has a widest frequency bandwidth among the plural different spectral components, a second spectral component corresponding to a predetermined frequency band close to a frequency that causes no chromatic aberration of the lens, and a third spectral component expressed in terms of a linear sum of a value resulting from multiplying the first spectral component by a first weighting factor and a value resulting from multiplying the second spectral component by a second weighting factor.

  • Patent number: 8169537
    Abstract: The present invention relates to a control method of a photographing apparatus, the photographing apparatus and a control program, which are capable of automatically determining a photographing mode capable of generating a sharper image. If a first exposure time is equal to or shorter than a first threshold value, a control circuit 18 makes a decision to take an input image in a first mode. The first exposure time is an exposure time required for taking one input image on the assumption that a photographing operation is carried out in the first mode for generating one output image by taking one input image. If the first exposure time is neither equal to nor shorter than the first threshold value, on the other hand, the control circuit 18 makes a decision to take a plurality of input images in a second mode provided that a second exposure time is equal to or shorter than a second threshold value.

  • Patent number: 8085313
    Abstract: The present invention relates to a method, apparatus and program for processing an image, capable of producing a sharp image. A digital camera 1 includes an imaging device 4 formed of a single-plane sensor that provides one color signal for each pixel. A plurality of images are captured at a high shutter speed by the imaging device 4 and stored in a frame memory 22 of a signal processor 7. The signal processor 7 detects a positional relationship among the plurality of images stored in the frame memory 22 and estimates a correct image with three color signals at each pixel, based on the detected positional relationship. The present invention is applicable, for example, to a digital camera.

  • Publication number: 20110280479
    Abstract: An apparatus and a method for efficiently executing correction of false color, such as purple fringe, caused by chromatic aberration and for generating and outputting high-quality image data are provided. A white-saturated pixel is detected from image data, a false-color-pixel detection area is set around the detected white-saturated pixel, and pixels having color corresponding to false color such as purple fringe are detected from the set area. The detected pixels are determined as false-color pixels and correction processing based on the values of the surrounding pixels is performed on the determined false-color pixels. With this configuration, an area of false color such as purple fringe generated in the neighborhood of a white-saturated pixel can be efficiently detected, pixel values can be partially corrected, and high-quality image data can be generated and output without affecting the entire image.

  • Publication number: 20100172589
    Abstract: An information processing apparatus includes a band-shaped area selecting section, an angle selecting section, and a control section. The band-shaped area selecting section selects, from among band-shaped areas each having a first angle with respect to a second direction orthogonal to a first direction, a first band-shaped area having a maximum height, which satisfies a condition that the first band-shaped area is on one side of a first point group, which is in the first direction and on one side of a second point group, which is in a direction opposite to the first direction. The angle selecting section selects a candidate for the first angle. The control section effects control to repeat selecting of the first band-shaped area and selecting of the candidate for the first angle, and obtains the finally selected first band-shaped area as a processing result.

  • Publication number: 20100149358
    Abstract: A whole image showing the entire range of the object of shooting is generated by picking up unit images, each constituting a part of the scenic range to be imaged, by sequentially shifting the image pickup direction, cutting out image regions of a predetermined size, each constituting a part of each of the unit images picked up in the image pickup step, so as to produce overlapping areas and sequentially and partly superposing the image region. The noise components of the image regions are uniformized to improve the image quality by cutting out image regions as to make two or more than two image regions overlap each other in average for the position of each unit image of the whole image to be generated.

  • Publication number: 20100053703
    Abstract: In an imaging apparatus, a function whose value increases in time is used as a threshold electric-signal level, and an electric-signal level of a photoreceptor element is compared with the threshold electric-signal level. Even if a light received by the photoreceptor element has a low luminance, the electric-signal level of the photoreceptor element crosses the threshold electric-signal level in a short time, allowing calculation of the amount of optical energy received by the photoreceptor element. Furthermore, when an object having a region where brightness changes in time and also having a region with a low luminance is imaged, imaging interval is changed in accordance with luminance. Accordingly, information regarding how the brightness of the object is rapidly changing in time can be obtained more precisely, and an image can be output without making a projection image of the dark region completely black.
