  • Patent number: 8199880
    Abstract: There is provided a technology that enables an operator to designate whether or not to continue imaging if divided capture has been interrupted in a radiographic apparatus. During continuation of divided capture, the state of an irradiation switch for designating irradiation of radiation is detected by an irradiation switch state detection unit. When a suspension of the designation of irradiation of radiation has been detected, information indicating continuation of imaging, performing of imaging again, or cancellation of imaging is presented to an operator, thereby preventing an unintended interruption of imaging.

  • Patent number: 8195009
    Abstract: This invention makes it possible to obtain an enlarged image while suppressing noise and maintaining the sharpness of an original image only by setting a simple enlargement ratio without no special knowledge. Original image data (Ia) is enlarged in accordance with a set enlargement ratio (E) to generate an enlarged image (IA). The enlarged image (IA) is smoothed by using a smoothing filter with a size depending on the enlargement ratio (E) to generate smoothed image data (IB). Difference image data (IC) is generated by calculating the difference between the enlarged image data (IA) and the smoothed image data (IB). The generated difference image data is multiplied by an emphasis coefficient. The product is added to the enlarged image data, thereby obtaining image data (IS) that has undergone enlargement/unsharp masking.

  • Patent number: 8189946
    Abstract: The intensities of horizontal and vertical edges of each block of luminance signals of an image are measured, and horizontal and vertical edge intensity data of respective blocks are stored for one frame in an edge intensity mapping memory. A noise removal flag used to specify a filtering block is calculated based on the edge intensity data, and is stored in a noise removal flag mapping memory. A filter controller controls whether or not to apply filtering processing to each block, specified by this noise removal flag, of the current frame of the image based on the horizontal and vertical edge intensity data of that block of the current frame and those of the corresponding block of the immediately preceding frame.

  • Patent number: 8190009
    Abstract: An optical apparatus capable of detecting an attitude of the apparatus in a state where no interference occurs between apparatus components, thereby preventing an error in the attitude detection. A shift lens drive controller of the optical apparatus detects a shake applied to the apparatus, calculates a movement target position of the shift lens based on a result of the detection, detects an actual position of the shift lens, and performs feedback control such that the actual position of the shift lens is converged to the movement target position. An attitude detector detects the attitude of the optical apparatus by using feedback control information, and an interference prevention controller prevents interference between the shift lens and other members.

  • Patent number: 8184309
    Abstract: This invention can cope with various user needs and use cases related to a holding function and can prevent any situation in which, for example, even when the holding function is disabled, an external device continuously inputs, to a printing apparatus, jobs which require use of the holding function. This invention also prevents the data of a job that requires use of the holding function from remaining in a memory when the holding function is disabled. This invention prevents data that will never be used from remaining in a storage area when the holding function is disabled. A printing system, according to the invention, enables a printing unit to execute a process of a job that requires use of the holding function of causing a storage unit to hold data of a job to be processed. The printing system includes a control unit which disables the holding function.

  • Patent number: 8184177
    Abstract: First white balance correction coefficients computed based on a detected face region, and second white balance correction coefficients for correcting, to a skin color, chromaticity obtained after applying the first white balance correction coefficients to the face region are obtained. The degree of detection reliability of the face region is determined based on the parameter values obtained from the pixels of the face region and predetermined conditions. Resultant white balance correction coefficients are computed from the first white balance correction coefficients and the second white balance correction coefficients to which a smaller weight is applied as the degree of detection reliability is lower. Even when a face region is erroneously detected, high-precision white balance correction coefficients can be obtained.
