摘要： In an imager including a sensor of solid state type having photo-elements arranged with a matrix configuration wherein electrical signals are read out from the photo-elements in two-row-at-a-time, the electrical signals are read out from 1st and 2nd rows for the 1st scan line of a display picture, from 3rd and 4th rows for the 2nd scan line, and so forth. In order to obtain a zoomed up picture of an area of a part of the matrix configuration of the photo-elements, there is provided a memory having storage locations whose number is equal to that of the photo-elements in the area to be zoomed up, each location being capable of storing the electrical signal from each photo-element and a circuit for reading out the memory row by row. The circuit reads locations in 1st and 2nd rows for the 1st scan line, in 2nd and 3rd rows for the 2nd scan line, and so forth. If the area comprises M rows, the numbers of the scan line obtained from the area are M/2 when a video signal is produced from the signal read out from the sensor and M when the video signal is produced from the signal read out from the sensor. Therefore, a picture display enlarged in the vertical direction is obtained.

摘要： Reading horizontal and vertical scanning circuits and a resetting vertical scanning circuit are connected to an image sensor including a plurality of photodiodes arranged in a matrix form. The resetting vertical scanning circuit generates vertical scanning pulses prior to the scanning of the reading vertical scanning circuit by a shutter time T.sub.S. Where the reading vertical scanning circuit performs a two-line-at-a-time reading, the resetting vertical scanning circuit also performs the two-line-at-a-time reading. The reading vertical scanning circuit reads the signal of the lines reset by the resetting scanning circuit and outputs it as a video signal.

摘要： A color video camera using a solid-state image pickup device having filters of the complementary color system consisting of a filter to transmit the light of all colors, a filter to transmit the yellow light, a filter to transmit the cyan light, and a filter to transmit the green light can obtain color signals having no color aliasing by selecting the conditions of the arithmetic operating processes of the signals corresponding to the respective filters. In these conditions, assuming that the signals corresponding to the four kinds of filters are represented by W, Ye, Cy and G in correspondence to the colors of the respective filters, a red signal and a blue signal are produced by the arithmetic operations represented by the following expressions:R=.alpha.W-.beta.Cy+.gamma.Ye-.delta.GB=.alpha.'W+.beta.'Cy-.gamma.'Ye-.delta.'Gwherein the respective arithmetic operational ratios .alpha., .beta., .gamma., .delta., .alpha.', .beta.', .gamma.', and .delta.' are set so as to satisfy the condition of the following expression:.alpha.W+.beta.Cy=.gamma.Ye+.delta.G or .alpha.'W+.gamma.'Ye=.beta.'Cy+.delta.'G.This setting is realized by setting the amplification factors of the amplifiers to amplify the respective signals which are output in correspondence to the respective filters so as to meet this condition and by adding and subtracting those outputs.
