Abstract
Abstract A solid state imaging apparatus having a plurality of cells for accumulating charge signals in response to an incident light and charge transfer means connected to the cells through a switching element. A read pulse and a transfer pulse are applied to the switching element and the transfer means, respectively, to read the charge signals from the cells and transfer those signals, so that a video signal is produced. Blooming suppression pulse synchronous with the transfer pulse is supplied to a node between the cell and the switching element through a capacitive coupling.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
108 words
A solid state imaging apparatus having a plurality of cells for accumulating charge signals in response to an intensity of an incident light from an object; charge transfer means connected to said cells through a switching element; and driving means for applying a read pulse and a transfer pulse to said switching element and said transfer means, respectively, to read the charge signals from said cells and transfer those signals, thereby producing a video signal, in which a blooming suppression means is provided for supplying a blooming suppression pulse synchronous with said transfer pulse to a node between said cell and said switching element through a capacitive coupling.
Claim 2
Dependent Claim
108 words
A solid state imaging apparatus having a plurality of cells for accumulating charge signals in response to an intensity of an incident light from an object; charge transfer means connected to said cells through a switching element; and driving means for applying a read pulse and a transfer pulse to said switching element and said transfer means, respectively, to read the charge signals from said cells and transfer those signals, thereby producing a video signal, in which a blooming suppression means is provided for supplying a blooming suppression pulse synchronous with said transfer pulse to a node between said cell and said switching element through a capacitive coupling.
Claim 3
Dependent Claim
30 words
A solid state imaging apparatus as claimed in claim 1, wherein the width of said blooming suppression pulse is selected to be greater than the width of said transfer pulse.
