Abstract
Abstract An image recording apparatus having a solid-state image pickup device (10), an A/D converter (16) for converting a one-frame analog image signal from the solid-state image pickup device (10) to a one-frame digital image signal, and a pixel memory (30) for recording outputs from the A/D converter (16). The image recording apparatus has an adder (26) for adding the output from the A/D converter (16) and the readout signal from the pixel memory (30), and for writing addition results into the pixel memory (30). A plurality of one-frame digital image signals are accumulated and an accumulation result is recorded in the memory (30), as a one-frame image signal.

Claim 2
Dependent Claim
88 words
An image recording apparatus comprising solid-state image pickup means (10), A/D converting means (16) for converting a one-frame analog image siqnal from said solid-state image pickup means (10) to a one-frame digital image signal, and recording means (30) for recording the one-frame digital image signal from said A/D converting means (16), characterized in that said recording means (26, 30) accumulates a plurality of one-frame digital image signals from said A/D converting means (16) to form a one-frame digital image signal and records the one-frame digital image signal accumulated.
Claim 3
Dependent Claim
93 words
An apparatus according to claim 1, characterized in that said recording means has a memory (30) for storing the one-frame digital image signal; an adder (26) having two input terminals respectively connected to output terminals of said A/D converting means (16) and said memory (30); and an output terminal connected to an input terminal of said memory (30); with said adder (26) adding the one-frame digital image signal produced from said A/D converter (16) and the one-frame digital image signal produced from the memory (30), writing the addition results into said memory (30).
