ABSTRACT:
There is disclosed a solid-state image pick-up apparatus provide with a solid-state image sensor such as a CCD image sensor, etc. This solid-state image pick-up apparatus comprises; a solid-state image sensor comprised of a plurality of photosensitive elements arranged in a form of a matrix having rows and columns, and responsive to a light incident thereonto to accumulate electric charges; a plurality of vertical shift registers coupled to the respective columns of the matrix of the photosensitive elements, and adapted for receiving electric charges from the photosensitive elements in response to a sensor gate signal; a storage section coupled to the vertical shift registers, and adapted for receiving electric charges from the vertical shift registers in response to a first transfer signal; a horizontal shift register coupled to the storage means, and adapted for receiving electric charges from the storage means in response to a second transfer signal for outputting, column by column, electric charges from the solid-state image sensor; and a timing signal generator for sweeping out independently ineffective electric charges accumulated in the photosensitive elements of the odd rows and those accumulated in the photosensitive elements of the even rows so that the accumulating period of effective electric charges is adjustably varied in a range from one field period to one frame period.
