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 row…
