Abstract: A camera microcomputer sets a gamma characteristic that suits a luminance input value/output value relationship in the entire luminance region extending from lower luminance to higher luminance of a video signal to a luminance input value/output value relationship of a referential gamma characteristic, irrespective of input dynamic range. A gamma correction processing unit performs gamma correction processing on a captured video signal in such a way as to convert the input value into the output value based on the set gamma characteristic.

Abstract: In an image capturing apparatus, a subject image is converted into an image signal, which undergoes automatic correction processing including white balance correction processing, and further undergoes image quality change processing. A first evaluation value indicating a largest value of an R signal, a G signal, and a B signal of the image signal undergone the image quality change processing and a second evaluation value indicating a luminance of the image signal undergone the image quality change processing are detected. A control evaluation value is calculated using weighted average of the first evaluation value and the second evaluation value according to at least one of an amount of image quality changing effect due to the image quality change processing and a reliability of the automatic correction processing, and exposure control is performed based on the control evaluation value.

Abstract: A flicker detection region in which an image signal has values relating to luminance and colors within predetermined ranges is extracted from a plurality of flicker detection regions allocated in the vertical and horizontal directions of an image. A flicker component is detected using the luminance information of the image signal in the extracted flicker detection region. A correction value to correct the flicker component is generated from the detected flicker component. This makes it possible to accurately correct, using a simple arrangement, a flicker component contained in an image sensed under a light source whose brightness periodically changes even when the object or the image sensing apparatus moves.

Abstract: An image sensing apparatus that controls exposure includes a signal processing unit for processing the output signal of a image sensing element, an aperture control unit for controlling aperture, and an external sensor for measuring the brightness of an object. In this case, exposure is controlled using the luminance information of both the image data and the external sensor, with the sampling period of the external sensor being set to be shorter than the accumulation period of the solid-state image sensing element. At least one of the aperture and the accumulation period is then controlled, based on the luminance information measured by the external sensor during the accumulation period.

Abstract: An image processing apparatus and an image processing method reconstruct a three-dimensional image of an object which expresses a texture, glossiness, and three-dimensionality with realism. The image processing apparatus produces, from a physical object, data representing a shape and a surface feature of the physical object, holds the data as a three-dimensional model, and presents a three-dimensional image under conditions of an illumination environment and line of sight designated by a user when the three-dimensional image is reconstructed. To present the three-dimensional image at a high speed with realism, the apparatus and method use new and particularly advantageous features in a generation process and in a data format used in the three-dimensional model.

Abstract: When an access request (a request for transfer of video and audio information or a request for a camera operation) to a camera apparatus connected to a network via a terminal is issued via the network, a camera management server processes the access request on the basis of an access right set by a user (or a manager) using the terminal to which the camera apparatus is connected. That is, the camera management server refers to an access right set file and grants or denies permission to access for the user whose has issued the access request. The user to whom the access permission is granted requests a camera control server to permit a camera operation via a camera control client and thereby can receive an image taken by the camera apparatus and voices collected by the camera apparatus and can perform panning, tilting, and zooming of the camera apparatus.

Abstract: A system utilizes the camera control server of the CPU to transfer the camera control command, received through the network, to the camera control device to control the camera in order to vary the audio input/output characteristics in linkage with the camera operation and to thereby improve the realistic feeling. In more details, the camera control server also sends control commands to the audio input control device, the audio output device and the video display control device according to the camera control thereby controlling the input characteristics (spreading, direction and sensitivity) of the microphone and the output characteristics (spreading, direction and depth) of the speaker and varying the image displayed on the monitor. The system also includes technology for displaying, on the monitor, the information on the operator of the camera and on the receiver of the image, and for varying the direction of the monitor according to the panning or tilting operation of the camera.
