摘要： An image pickup device includes a horizontal inversion section 6 for horizontally inverting at least a third one of first to third pixels signals to be outputted from individual CCD units 2a to 2c corresponding to R, G, and B, and a CCD actuation control section 9 capable of controlling the first to third CCD units 2a to 2c so that pixels, 2n+1 (n=0, 1, 2, . . . ) in each set, in a horizontal direction are subjected to the pixels addition set by set. The CCD actuation control section 9 performs control such that the second pixel signal is subjected to the pixel addition at timings delayed by n pixels with respect to timings for the first pixel signal, and the third pixel signal is subjected to the pixel addition at timings delayed by n pixels with respect to the timings for the second pixel signal. With this image pickup device, a high-sensitivity image can be obtained with the resolution impairment being suppressed.

摘要： An image sensing device free from change in the angle of view between taking moving picture and taking still picture, small in power consumption in moving picture taking, and small in sensitivity drop if the size of the optical system is the same. The image sensing means has exclusive image sensing elements for red (R), green (G), and blue (B), and the three image sensing elements are disposed by shifting the pixels obliquely. Luminance signal generating means generates a first luminance signal of which number of pixels in the horizontal direction is 2 times that of the image sensing device for G, and generates a second luminance signal of which number of pixels in the horizontal direction is 2 times that of the image sensing device for G. Sampling frequency converting means decreases the sampling frequency at a specific ratio, and generates as a third luminance signal. Second memory means stores the first luminance signal and second luminance signal, and issues them alternately in every line. This image sensing device utilizes the output signal of the sampling frequency converting means as a moving picture output, and the output of the second memory means as a still picture output.

摘要： A light guide plate which can achieve improvement of back-lighting or front-lighting luminance without increase of luminance of a light source, and a liquid crystal display device using such a light guide plate. A large number of concave small dots are formed in a surface of the light guide plate opposite to a light emitting surface of the light guide plate which emits light to a liquid crystal cell array so that light incident on the light guide plate from the light source is reflected at the concave small dots in the direction toward the light emitting surface of the light guide plate. Each of the concave small dots is shaped like a triangle with a sectional inclination angle of from 50 to 60° in sectional view and shaped like an approximate rectangle or square in plan view in the direction perpendicular to a surface of the light guide plate and disposed so that a long side of the approximate rectangle or a side of the approximate square is approximately parallel with the longitudinal direction of the light source.

摘要： The image capture device of this invention includes: an optical system for producing a subject image; an imager, which receives the subject image and outputs an image signal representing the subject image; and an image processing section for zooming in on, or out, a given image based on the image signal and in accordance with information about a zoom power specified, to generate a new image signal with the zoom power changed. Until the zoom power specified reaches a predetermined value, the processing section zooms in on the image by interpolating pixels so that degree of sharpness given to the image increases. If a value representing illuminance of the image is a predefined value or more and if the zoom power is the predetermined value or more, the processing section fixes the degree of sharpness given to the image. And if the value representing the illuminance of the image is less than the predefined value and if the zoom power specified is the predetermined value or more, the processing section decreases the degree of sharpness given to the image.
