    • A housing (17) that accommodates a light source (1), a display device (3), etc. has an intake aperture (18) and an exhaust aperture (24). A blowing unit (16, 23) sucks air in through the intake aperture and expels air out through the exhaust aperture. A filter unit (19) is disposed so that a filter (20) faces the intake aperture in a predetermined area between a rolling shaft (31a) and a take-up shaft (31b). A part of the filter facing the intake aperture is renewed by taking-up the filter from the rolling shaft onto the take-up shaft. A control unit (36) performs control so as to renew the filter for a range that is smaller than an opening area of the intake aperture, when a predetermined renewal condition is determined to be satisfied, based on the output of a detection unit (38, 39a, 39b) that detects a specific factor value relating to contamination of the filter, such as a cumulative display time, a temperature, an air pressure, etc. This reduces a noise occurring during the driving of a fan or a change in the rotational speed of the fan, which are associated with automatic filter renewal.

    • In a data communication system including a reception side PC for receiving data, a transmission source PC for transmitting data, and a data transfer apparatus, the reception side PC notifies the transmission source PC of a reception ID as an identifier for specifying the reception side PC in data communication. Upon receiving a transmission notification containing the reception ID from the transmission source PC, the reception side PC requests a list of data corresponding to the transmission notification of the data transfer apparatus. The reception side PC requests, of the data transfer apparatus, acquisition target data based on the list of data transmitted from the data transfer apparatus in response to the request, and then acquires the data.

    • An image pickup apparatus in which, a taking lens is installable or fixed, includes an image pickup element in which, pixels having a photoelectric conversion portion are arranged two dimensionally. The pixels include focal-point detection pixels which are arranged to restrict a direction of incidence of a light beam which is incident, and image-pickup pixels which are arranged such that, the direction of incidence of the light beam which is incident is not restricted more than the direction of incidence restricted by the focal-point detection pixel.The focal-point detection pixel outputs at least a signal for ranging, and the image-pickup pixel outputs at least a signal for an image.The image pickup apparatus includes an overflow judging section which judges whether or not the photoelectric conversion portion has overflowed, and a calculating section which calculates an amount of defocus based on a judgment result of the overflow judging section and the signal for ranging.

    • In a frame-by-frame color image pickup apparatus, images of light components transmitted through red, green, and blue filters of a rotating filter are introduced to an image pickup device arranged in an optical path with rotating filter. The cells in the image pickup device are grouped into cell blocks, each block made up of four cells arranged in one horizontal row and four vertical columns. The rotational speed of the rotating filter is increased, and the cells within each block selected by switches for reading are fixed when an image is dynamic, a quarter of all the cells are read at one cycle of revolution of the rotating filter, and the remaining cells are interpolated to form one frame image. Color breakup is thus precluded. When an image is still, the cells selected are switched at each cycle of revolution of the rotating filter, and all the cells are read over four cycles of revolution of the rotating filter. Thus, a high resolution color image is obtained. The color image pickup apparatus thus improves virtually a pickup rate from the image pickup device, alleviating color breakup. The still image is presented without degrading its resolution.
    • 在逐帧彩色图像拾取装置中,通过旋转滤光器的红色,绿色和蓝色滤色器透射的光分量的图像被引入到布置在具有旋转滤光器的光路中的图像拾取装置中。 图像拾取装置中的单元被分组为单元块,每个块由布置在一个水平行和四个垂直列中的四个单元组成。 旋转滤波器的旋转速度增加,当图像动态时,由用于读取的开关选择的每个块内的单元是固定的,在旋转滤波器的一个旋转循环中读取所有单元的四分之一,剩余的 单元被内插以形成一帧图像。 因此排除了颜色分解。 当图像仍然存在时,选择的单元在旋转滤波器的每个旋转循环中被切换,并且所有单元在旋转滤波器的四个循环周期中被读取。 因此,获得高分辨率彩色图像。 因此,彩色图像拾取装置实际上从图像拾取装置提高了拾取速率,从而减轻了颜色分解。 静态图像呈现而不降低其分辨率。
