Abstract
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.
