Problems solved by technology

[0019] Although these are two independent phenomena, the generation mechanism is the same in FPN and continuity (continuity of linear noise in vertical transfer period, continuity of point noise between frames or fields), so that if both Generate linear noise and point noise, then linear noise always appears on the screen

Embodiment Construction

[0049] In the embodiment to be described below, generation of basic timing will be described by exemplarily using pulses Vφ1 to Vφ6 similar to those shown in the timing charts of FIGS. 5 and 8 . The rising timing of pulse Vφ6 is T1, the falling timing of pulse Vφ2 is T2, the rising timing of pulse Vφ1 is T3, the falling timing of pulse Vφ3 is T4, the rising timing of pulse Vφ2 is T5, the falling timing of pulse Vφ4 is T6, and the falling timing of pulse Vφ3 is T6. The rising timing of the pulse Vφ5 is T7, the falling timing of the pulse Vφ5 is T8, the rising timing of the pulse Vφ4 is T9, the falling timing of the pulse Vφ6 is T10, the rising timing of the pulse Vφ5 is T11, and the falling timing of the pulse Vφ1 is T12.

[0050] FIG. 1 is a schematic diagram of a timing generator equipped with an example of a transfer pulse generator circuit to which the present invention is applied. The composition of the timing generator 1 shown in the figure is: a horizontal direction coun...

Abstract

A transfer pulse generator circuit for outputting a vertical register transfer pulse includes a transfer pulse control device for controlling the rising and falling timing of the vertical register transfer pulse to be set to a desired timing within a predetermined period.

Description

technical field [0001] The invention relates to a transfer pulse generator circuit and an image pickup device. More particularly, the present invention relates to a transfer pulse generator circuit for generating a vertical register transfer pulse for driving a vertical register of a charge-coupled device (CCD) type solid-state image pickup device, and to a An image pickup device equipped with a CCD type solid-state image pickup device having a transfer pulse generator circuit. Background technique [0002] In an image pickup apparatus equipped with a CCD-type solid-state image pickup device, charges accumulated in each light-receiving element provided in the light-receiving portion of the CCD-type solid-state image pickup device are transferred to vertical registers, transferred to each vertical The charge of the register is transferred to the horizontal register, and the charge transferred to the horizontal register is transferred to the output circuit. The output from t...
