<P>PROBLEM TO BE SOLVED: To provide an efficient image transmission system capable of transmitting an image with high definition and high image quality like those of a photograph at a high speed while converting the arrangement of pixels of the image by using an imaging apparatus with the number of pixels equal to and more than that of a high image quality television (HDTV: High Definition TV) image such as the High Vision system and capable of securing the security. <P>SOLUTION: A vertical address generator 24 and a horizontal address generator 25 in an arrangement conversion unit in a camera use division signals HDO', HD1', HD2', HD3' whose number of pixels as HDTV digital parallel signals is the same as that of prior arts in order to secure the security of image signals. As shown in Figure (E), the division signal HD0' results from reading pixel data at an interval of one both in longitudinal and lateral directions. The division signals HD1', HD2', HD3' result from reading pixel data at an interval of one both in the longitudinal and lateral directions while respectively changing the read position by one each both in the longitudinal and lateral directions. Thus, the four division signals HD0' to HD3' whose number of pixels is the same as that in a standard state but whose pixel arrangement differs from that in the standard state can be obtained in this way. <P>COPYRIGHT: (C)2004,JPO |
