In measuring a spectral irradiance distribution of light, light is irradiated to n (natural number) light-transit sections, which respectively have n kinds of given optical characteristic coefficients, and s (natural number) optical sensors, which respectively have s kinds of given spectral sensitivities, receive the light via the n light-transit sections and detects individual responses for the received light. Then a calculating section calculates m (natural number) spectral irradiances for m kinds of wavelengths as a spectral irradiance distribution based on linear formulae established between the optical characteristic coefficients, the spectral sensitivities, (n×s) responses for the light obtained by the s optical sensors, and the spectral irradiance distribution of the light.

Image data from an upper apparatus is compressed by a compressing unit, the compressed image data is transferred to a display apparatus by a printer interface of a low speed, and the original image data is reconstructed by a decoding unit and displayed. The display apparatus is a projector and auxiliarily displays a second picture plane into a first picture plane for presentation by an independent liquid crystal panel. A phase transition type liquid crystal panel of a number of pixels and a high resolution is used to display the first picture plane and the image data is compressed and transferred and is displayed. As a second picture plane, a personal computer picture plane is transferred and displayed as it is.

摘要:
When a plurality of images are to be overlapped and synthesized, coincidence degrees between the plurality of images in an area near the boundary of a common area are calculated, and the plurality of images are overlapped and synthesized so that an area near the boundary having a high coincidence degree appears on the overlapped image. Thereby, it is possible to avoid the duplexing of the subject in the common area and unnatural ruptures on the boundary made by the overlapping while reducing the number of processes for the synthesizing.

An image processing apparatus creates a basic-structure component image representing an image that an input image except edge is smoothed while preserving the edge in the input image; and creates a detail component image representing an image that the basic-structure component image is subtracted from the input image. Subsequently, the image processing apparatus decomposes the detail component image into a plurality of frequency-band images through multiresolution transform processing, and performs noise removal on the obtained frequency-band images. After that, the image processing apparatus performs inverse multiresolution transform processing of combining the noise-removed frequency-band images, thereby creating a noise-removed detail-component image.

摘要:
An image processing apparatus includes a face detection processing unit that reduces an image of a frame to be processed to a first level among several reduction levels to generate a reduced image of the frame to be processed, with one of frames included in a moving image as the frame to be processed, and compares the reduced image generated by the reducing unit and the learning data to extract a face image from the reduced image. When the extraction of the face image from the frame to be processed is ended, the face detection processing unit updates the frame to be processed to a next frame subsequent to the frame to be processed and generates a reduced image that is reduced to another level other than reduction levels adjoining the first level.
