Title: Driving method of solid-state image pickup device
Inventor: SONE MASAAKI
IPC: H04N5/335
Filed: 1983-02-10
Abstract: PURPOSE:To reduce effectively vertical smear by transferring and storing a noise charge component in a vertical transfer means to a horizontal transfer means, transferring this stored charge to a temporary storage device and compensating an output signal of the solid-state image pickup device with the signal. CONSTITUTION:When a strong light is irradiated, a signal charge 25 is generated in a photo diode 21 and a charge 26 generated in diodes other than the diode 21 by a light penetrating the diode 21 is mixed on a vertical transfer means 22. This mixed charge 26 is stored in response to the penetrated light at all times. As a result, the vertical smear component is included uniformly among the horizontal transfer means 23 from the location where the strong light 24 is irradiated. The means 23 is stopped and before the content of the diode 21 is transferred to the means 22, the component 26 is stored in the means 23 as long as possible. As a result, the smear charge component 27 in the means 23 is increased. When the component 27 is increased more than the transfer capacity of the means 23, the number of transfer of vertical smear to the means 23 is controlled to an optimum value.

Abstract: PURPOSE:To reduce the variation of the picture quality of each block. CONSTITUTION:A switch 122 is switched so that the quantization error of an input picture position applied from an inverse discrete cosine converter 22 can be inputted to an absolute value sum calculator 123 only when the input picture element is selected by a selector 121. The absolute value sum calculator 123 calculates the absolute value sum of the selected quantization error by each block unit, the calculated absolute value sum is compared with a set threshold value by a comparator 124, and a judgement signal indicating the result is outputted to a quantizer 16. When the judgement signal indicates that the absolute value sum is larger than the threshold value, the quantizer 16 quantizes a conversion factor stored in a memory 14 again by using a new quantization scale prepared by subtracting a value DELTA (>0) from the quantization scale.
