The object is to provide an image capture device capable of carrying out good image capture in electronic viewfinder mode. When the electronic viewfinder mode is set in a single lens reflex digital camera a quick return mirror is driven so as to direct light from a photographic subject onto a CCD, and control is also carried out such that images captured by the CCD are displayed as a through image on a liquid crystal monitor at specific time intervals, with the through image display conditions being adjusted so that the image displayed as a through image is an image equivalent to an image that would be captured during main image capture with the set main image capture conditions.

Image capture device capable of improved image capturing in electronic viewfinder mode

A CCD has transferring gates to which gate pulses for transferring only pixel information of pairs of two adjoining lines with intervals of a plurality of lines to vertical transferring routes are applied when the image signals with the low definition are produced. Thus, a frame rate can be maintained high and reduced image signals without untrue colors can be obtained.

Apparatus and method to capture image and other data and recording onto multiple recording medium

An image signal outputted from a CCD is converted into a digital signal by an A/D converter via a sampling hold circuit. After A/D conversion, the image data before image processing is stored in a first memory. A signal processing part performs image processing with respect to the unprocessed image data read out from the first memory in view of image property parameter data in accordance with an instruction from a CPU. The image after the image processing is displayed on a display. The user looks at the displayed image and selects, through an image property setting device, an image property parameter that the user desires, then inputs instructions such as change of parameter and adjustment. The signal processing part executes re-processing with respect to the unprocessed image data read out from the first memory, in accordance with new image property parameter data that is newly set by the user. The image property parameters are: white balance, gradation, gain, tonality, sharpness, and so forth.

Device and method for processing unprocessed image data based on image property parameters

An imaging part and sensors are provided on an eyeglasses-shaped frame, which connects to a body through a cable. When a cameraman wears the frame just like eyeglasses, a taking lens is directed in the same direction that the face of the cameraman faces, so that a subject to be captured can be in the same direction as a line of sight of the cameraman. The sensors generate detection signals upon detecting movement of muscles at the temples of the cameraman by detecting myoelectric impulses. The image recording apparatus is controlled in accordance with the detection signals, which represent an arrangement of the movement for control. For example, when the cameraman closes the right eye to move the muscles at the right temple, the subject is zoomed in, and when the cameraman closes both eyes, the captured image is recorded.

Image recording apparatus

Shading data are captured in a state where there is no developed film between a light source and a line sensor. During calibration, a negative base area on the film is positioned between the light source and the line sensor, and signal levels of colors of color signal data corresponding to three primary colors transmitted through the negative base area are controlled to be substantially equal. While the film is transported, the color signal data indicating a frame image are obtained in the calibrated state, and shading correction is performed for the color signal data according to the obtained shading data.

Film image input device and method

A white balance control device is provided for use in a video camera or a still video camera in which white balance control signals are controlled so that an object may be photographed without the occurrence of color failure. A user selects the light source to be employed. A microcomputer of the white balance control device detects a difference between integral averaged values for two color difference signals R-Y and B-Y and a reference value. The integral averaged values are to be equalized until this difference is within a predetermined value. The integral averaged values are also to be maintained within a variable region in accordance with the selected light source. Use of the variable region insures that deterioration of the reproduced color does not occur even when there is a difference between a selected light source and an actual color temperature.

A white balance control device is provided for use in a video camera or a still video camera in which white balance control signals are controlled so that an object may be photographed without the occurrence of color failure. A microcomputer of the white balance control device detects a difference between integral averaged values for two color difference signals R-Y and B-Y and a reference value. Depending on the difference, values of the white balance control signals Rcont and Bcont may be changed when the brightness of an object is changed by more than a predetermined amount. In an indoor mode, the values of the white balance control signals Rcont and Bcont are positioned within a region corresponding to various artificial light sources. In an outdoor mode, the values of the white balance control signals are positioned within a region corresponding to natural light.

White balance control device for use in both an outdoor and indoor mode

A white balance control device is provided for use in a video camera or a still video camera, each having zoom capabilities, in which white balance control signals are controlled so that an object may be photographed without the occurrence of color failure. A recognition level or threshold is set as a function of zoom information. A microcomputer of the white balance control device detects a difference between integral averaged values for two color difference signals R-Y and B-Y and a reference value. Depending on the difference, values of the white balance control signals Rcont and Bcont may be changed when the brightness of an object is changed by more than the recognition level. However, the values are positioned within a variable region and when the values of the white balance control signals Rcont and Bcont become constant, the variable region is renewed.
